Re: What's wrong with latest Pharo?

Guillermo Polito
Hi Tim,

Looking at the resolution of the libgit library, I see that in pharo7 the following:

LGitLibrary >> unixModuleName
| pluginDir |
pluginDir := Smalltalk vm binary parent.
#('libgit2.so' 'libgit2.so.0')
detect: [ :each | (pluginDir / each) exists ] 
ifFound: [ :libName | ^ libName ].

self error: 'Module not found.'

That definition may be the root of the problem in linux because it is returning the unqualified library name without the VM path.
Then, the order of resolution of libraries is the one in the operating system, which is in your case probably searching in /usr/lib or something like that.
I'd bet that you have in your system (/usr/lib/something) another libgit version but probably not matching the expected version in pharo or the architecture of pharo (32/64 bits).
Thus, pharo finds the library but cannot load it...

If you check in Pharo8, the same method reads slightly different:

LGitLibrary >> unixModuleName
| pluginDir |
pluginDir := Smalltalk vm binary parent.
#('libgit2.so' 'libgit2.so.0')
detect: [ :each | (pluginDir / each) exists ] 
ifFound: [ :libName | ^ (pluginDir / libName) fullName ].

self error: 'Module not found.'

Can you check that patching the method like that works in your case?
This maybe deserves a backporting as it may make it super complicated to work with Iceberg in some linuxes...

Did we ever get the bottom of installing Pharo on linux? I have a user on Arch linux who installed pharo from AUR (this is new stuff to me) - and once they downloaded an image - they now get an error that looks suspiciously like this libgit2 debacle - so I’m wondering what the solution was?

The error is:

No, you can't install libcurl3 with libcurl4. There is a known conflict between them: https://bugs.launchpad.net/ubuntu/+source/curl/+bug/1754294, https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=900511

Ubuntu 18.4 don't come with curl, but I think it comes with libcurl3 (I don't have means to verify it now), but when you install curl, it installs libcurl4 and removes libcurl3.

apt-cache search
reports everything it knows about, not just things that are INSTALLED.
For example, apt-cache search reports lua-curl-dev, but it is not
installed.
apt list | grep lua-curl-dev

The fact that neither libcurl3 nor libcurl4 is initially installed
means that either of them can be installed without conflict.

What do you mean? Under WSL I have installed Ubuntu 18.4 and for...

I see libcurl3 and libcurl4

Installing curl don't work because there is a conflict between curl version name used on Ubuntu and that used by Pharo, you can't install libcurl 3 and libcru4 together. Ubuntu 18 comes with libcurl4 and older software depending on libcurl3 broke with it. I tested with minidebian and it also failed.

Richard, was you able to use Iceberg? It should only work if either Ubuntu fix this dependency problem with libcurl or Pharo started to use libcrl4.

I have Pharo 6.1 and Pharo 7.0 working in Ubuntu 18.04
with no trouble so far.  I just downloaded the launcher
from pharo.org and pulled the images down that way.

One thing I do find annoying in Ubuntu 18.04 is the
number of programs (like okular) that spew warning
messages out the terminal.  Pharo, sadly, is one of
them.  Whenever a debugger window comes up in Pharo
there is spewage on the terminal.  But it works.

Ubuntu 18.04 LTS is, IMHO, is royal piece of crap. Ubuntu seems to have abandoned programmers tools almost completely in 18.04. I’ve had more problems with support of programming tools in 18.04, more than even Windows. I have run ‘sudo apt install’ maybe 80 times to install tools and libraries. Ubuntu 18.04’s hardware support is also lame compared to 16.04.
Personally , I’m not surprised that Pharo doesn’t run on 18.04. I stopped installing 18.04 on my new machines, after all 16.04 still has a few years of support going for it, and at least it works without hours of upgrading.

Re: What's wrong with latest Pharo?

Tim Mackinnon
Hi Guille - I’m not using Arch Linux myself - this was a seasoned exercism contributor trying to give pharo a spin - and sadly it hasn’t gone well (shame as they might have been an advocate) They also commented:

"I'm not quite sure though if I really want to continue from here. As someone new to pharo, I basically can't find any installation instructions that go beyond that evil `curl`. I'm happy to play this to the end with you, that at least exercism gets proper instructions, but the pharo community really should change their mind and provide more and better documentation about systemwide installation and packages. I have a hard time seeing something used at my compnay that does not provide an RPM out of the box…”

Which is fair play.

However I did get some details which might salvage something (and maybe they can try)

Its ArchLinux (apparently there are no versions in Arch, its always the latest).
Pharo wa installed via AUR (looks like a bit old - 2019-01-24 18:18) - not sure that is the issue though
AUR does give an image so they downloaded the latest 64 bit one from here - https://files.pharo.org/image/70/
Libgit2 was missing - that was installed (not clear on how - could ask)

After all of this - it did launch - they saw a welcome screen then it crashed (I think they were doing our eval string to metacello load exercism - so it would then use libgit2)

They then got this error:

I’ve pasted the error below - for prosperity.

Hi Tim,

Looking at the resolution of the libgit library, I see that in pharo7 the following:

LGitLibrary >> unixModuleName
| pluginDir |
pluginDir := Smalltalk vm binary parent.
#('libgit2.so' 'libgit2.so.0')
detect: [ :each | (pluginDir / each) exists ] 
ifFound: [ :libName | ^ libName ].

self error: 'Module not found.'

That definition may be the root of the problem in linux because it is returning the unqualified library name without the VM path.
Then, the order of resolution of libraries is the one in the operating system, which is in your case probably searching in /usr/lib or something like that.
I'd bet that you have in your system (/usr/lib/something) another libgit version but probably not matching the expected version in pharo or the architecture of pharo (32/64 bits).
Thus, pharo finds the library but cannot load it...

If you check in Pharo8, the same method reads slightly different:

LGitLibrary >> unixModuleName
| pluginDir |
pluginDir := Smalltalk vm binary parent.
#('libgit2.so' 'libgit2.so.0')
detect: [ :each | (pluginDir / each) exists ] 
ifFound: [ :libName | ^ (pluginDir / libName) fullName ].

self error: 'Module not found.'

Can you check that patching the method like that works in your case?
This maybe deserves a backporting as it may make it super complicated to work with Iceberg in some linuxes...

No, you can't install libcurl3 with libcurl4. There is a known conflict between them: https://bugs.launchpad.net/ubuntu/+source/curl/+bug/1754294, https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=900511

Ubuntu 18.4 don't come with curl, but I think it comes with libcurl3 (I don't have means to verify it now), but when you install curl, it installs libcurl4 and removes libcurl3.

For example, apt-cache search reports lua-curl-dev, but it is not

apt list | grep lua-curl-dev

The fact that neither libcurl3 nor libcurl4 is initially installed
means that either of them can be installed without conflict.

Richard, was you able to use Iceberg? It should only work if either Ubuntu fix this dependency problem with libcurl or Pharo started to use libcrl4.

One thing I do find annoying in Ubuntu 18.04 is the
number of programs (like okular) that spew warning

them.  Whenever a debugger window comes up in Pharo
there is spewage on the terminal.  But it works.

I’ve had more problems with support of programming tools in 18.04, more than even Windows. I have run ‘sudo apt install’ maybe 80 times to install tools and libraries. Ubuntu 18.04’s hardware support is also lame compared to 16.04.
Personally , I’m not surprised that Pharo doesn’t run on 18.04. I stopped installing 18.04 on my new machines, after all 16.04 still has a few years of support going for it, and at least it works without hours of upgrading.

Re: What's wrong with latest Pharo?

Tim Mackinnon
Actually - the user has confirmed a bit more (which sounds like your hunch Guille):

Hmm… Just loading the image without `eval`ing something seems to boot up well. But then I also realise, that there is a warning:

```ioLoadModule(/opt/pharo/bin/../lib/pharo/5.0-201901231209/libgit2.so):
  libcurl-gnutls.so.4: cannot open shared object file: No such file or directory```
(edited)

So this looks like pharo tries to load a bundled libgit2 first during bootup which fails and only later, when trying to call into it, system resolves into the system installed one.
Which then causes the segfault for some reason.

I’ll see if I can guide him through changing that method.

Hi Guille - I’m not using Arch Linux myself - this was a seasoned exercism contributor trying to give pharo a spin - and sadly it hasn’t gone well (shame as they might have been an advocate) They also commented:

"I'm not quite sure though if I really want to continue from here. As someone new to pharo, I basically can't find any installation instructions that go beyond that evil `curl`. I'm happy to play this to the end with you, that at least exercism gets proper instructions, but the pharo community really should change their mind and provide more and better documentation about systemwide installation and packages. I have a hard time seeing something used at my compnay that does not provide an RPM out of the box…”

Which is fair play.

However I did get some details which might salvage something (and maybe they can try)

Its ArchLinux (apparently there are no versions in Arch, its always the latest).
Pharo wa installed via AUR (looks like a bit old - 2019-01-24 18:18) - not sure that is the issue though
AUR does give an image so they downloaded the latest 64 bit one from here - https://files.pharo.org/image/70/
Libgit2 was missing - that was installed (not clear on how - could ask)

After all of this - it did launch - they saw a welcome screen then it crashed (I think they were doing our eval string to metacello load exercism - so it would then use libgit2)

They then got this error:

I’ve pasted the error below - for prosperity.

Hi Tim,

Looking at the resolution of the libgit library, I see that in pharo7 the following:

LGitLibrary >> unixModuleName
| pluginDir |
pluginDir := Smalltalk vm binary parent.
#('libgit2.so' 'libgit2.so.0')
detect: [ :each | (pluginDir / each) exists ] 
ifFound: [ :libName | ^ libName ].

self error: 'Module not found.'

That definition may be the root of the problem in linux because it is returning the unqualified library name without the VM path.
Then, the order of resolution of libraries is the one in the operating system, which is in your case probably searching in /usr/lib or something like that.
I'd bet that you have in your system (/usr/lib/something) another libgit version but probably not matching the expected version in pharo or the architecture of pharo (32/64 bits).
Thus, pharo finds the library but cannot load it...

If you check in Pharo8, the same method reads slightly different:

LGitLibrary >> unixModuleName
| pluginDir |
pluginDir := Smalltalk vm binary parent.
#('libgit2.so' 'libgit2.so.0')
detect: [ :each | (pluginDir / each) exists ] 
ifFound: [ :libName | ^ (pluginDir / libName) fullName ].

self error: 'Module not found.'

Can you check that patching the method like that works in your case?
This maybe deserves a backporting as it may make it super complicated to work with Iceberg in some linuxes...

Did we ever get the bottom of installing Pharo on linux? I have a user on Arch linux who installed pharo from AUR (this is new stuff to me) - and once they downloaded an image - they now get an error that looks suspiciously like this libgit2 debacle - so I’m wondering what the solution was?

The error is:

No, you can't install libcurl3 with libcurl4. There is a known conflict between them: https://bugs.launchpad.net/ubuntu/+source/curl/+bug/1754294, https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=900511

Ubuntu 18.4 don't come with curl, but I think it comes with libcurl3 (I don't have means to verify it now), but when you install curl, it installs libcurl4 and removes libcurl3.

apt-cache search
reports everything it knows about, not just things that are INSTALLED.
For example, apt-cache search reports lua-curl-dev, but it is not
installed.
apt list | grep lua-curl-dev

The fact that neither libcurl3 nor libcurl4 is initially installed
means that either of them can be installed without conflict.

Installing curl don't work because there is a conflict between curl version name used on Ubuntu and that used by Pharo, you can't install libcurl 3 and libcru4 together. Ubuntu 18 comes with libcurl4 and older software depending on libcurl3 broke with it. I tested with minidebian and it also failed.

Richard, was you able to use Iceberg? It should only work if either Ubuntu fix this dependency problem with libcurl or Pharo started to use libcrl4.

I have Pharo 6.1 and Pharo 7.0 working in Ubuntu 18.04

from pharo.org and pulled the images down that way.

One thing I do find annoying in Ubuntu 18.04 is the
number of programs (like okular) that spew warning
messages out the terminal.  Pharo, sadly, is one of
them.  Whenever a debugger window comes up in Pharo
there is spewage on the terminal.  But it works.

Ubuntu 18.04 LTS is, IMHO, is royal piece of crap. Ubuntu seems to have abandoned programmers tools almost completely in 18.04. I’ve had more problems with support of programming tools in 18.04, more than even Windows. I have run ‘sudo apt install’ maybe 80 times to install tools and libraries. Ubuntu 18.04’s hardware support is also lame compared to 16.04.
Personally , I’m not surprised that Pharo doesn’t run on 18.04. I stopped installing 18.04 on my new machines, after all 16.04 still has a few years of support going for it, and at least it works without hours of upgrading.

Re: What's wrong with latest Pharo?

Tim Mackinnon
Guille - it looks like modifying that method and :
"I installed some other package (`libcurl-gnutls`) which is an "addon" to the regular `libcurl`.”

Got us further - now he’s getting IceAuthenticationError- which could be down to git vs https. (I can use the #remoteTypeSelector: trick to hopefully fix that).

When I confirm everything, I will report back the magic syntax (at least for Arch) - as well as the desire to back port that fix to 7.

Thanks for chipping in (and this is the thread that keeps on giving…)

Actually - the user has confirmed a bit more (which sounds like your hunch Guille):

Hmm… Just loading the image without `eval`ing something seems to boot up well. But then I also realise, that there is a warning:

```ioLoadModule(/opt/pharo/bin/../lib/pharo/5.0-201901231209/libgit2.so):
  libcurl-gnutls.so.4: cannot open shared object file: No such file or directory```
(edited)

So this looks like pharo tries to load a bundled libgit2 first during bootup which fails and only later, when trying to call into it, system resolves into the system installed one.
Which then causes the segfault for some reason.

I’ll see if I can guide him through changing that method.

Hi Guille - I’m not using Arch Linux myself - this was a seasoned exercism contributor trying to give pharo a spin - and sadly it hasn’t gone well (shame as they might have been an advocate) They also commented:

"I'm not quite sure though if I really want to continue from here. As someone new to pharo, I basically can't find any installation instructions that go beyond that evil `curl`. I'm happy to play this to the end with you, that at least exercism gets proper instructions, but the pharo community really should change their mind and provide more and better documentation about systemwide installation and packages. I have a hard time seeing something used at my compnay that does not provide an RPM out of the box…”

Which is fair play.

However I did get some details which might salvage something (and maybe they can try)

Its ArchLinux (apparently there are no versions in Arch, its always the latest).
Pharo wa installed via AUR (looks like a bit old - 2019-01-24 18:18) - not sure that is the issue though
AUR does give an image so they downloaded the latest 64 bit one from here - https://files.pharo.org/image/70/
Libgit2 was missing - that was installed (not clear on how - could ask)

After all of this - it did launch - they saw a welcome screen then it crashed (I think they were doing our eval string to metacello load exercism - so it would then use libgit2)

They then got this error:

I’ve pasted the error below - for prosperity.

Hi Tim,

Looking at the resolution of the libgit library, I see that in pharo7 the following:

LGitLibrary >> unixModuleName
| pluginDir |
pluginDir := Smalltalk vm binary parent.
#('libgit2.so' 'libgit2.so.0')
detect: [ :each | (pluginDir / each) exists ] 
ifFound: [ :libName | ^ libName ].

self error: 'Module not found.'

That definition may be the root of the problem in linux because it is returning the unqualified library name without the VM path.
Then, the order of resolution of libraries is the one in the operating system, which is in your case probably searching in /usr/lib or something like that.
I'd bet that you have in your system (/usr/lib/something) another libgit version but probably not matching the expected version in pharo or the architecture of pharo (32/64 bits).
Thus, pharo finds the library but cannot load it...

If you check in Pharo8, the same method reads slightly different:

LGitLibrary >> unixModuleName
| pluginDir |
pluginDir := Smalltalk vm binary parent.
#('libgit2.so' 'libgit2.so.0')
detect: [ :each | (pluginDir / each) exists ] 
ifFound: [ :libName | ^ (pluginDir / libName) fullName ].

self error: 'Module not found.'

Can you check that patching the method like that works in your case?
This maybe deserves a backporting as it may make it super complicated to work with Iceberg in some linuxes...

No, you can't install libcurl3 with libcurl4. There is a known conflict between them: https://bugs.launchpad.net/ubuntu/+source/curl/+bug/1754294, https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=900511

Ubuntu 18.4 don't come with curl, but I think it comes with libcurl3 (I don't have means to verify it now), but when you install curl, it installs libcurl4 and removes libcurl3.

For example, apt-cache search reports lua-curl-dev, but it is not

apt list | grep lua-curl-dev

The fact that neither libcurl3 nor libcurl4 is initially installed
means that either of them can be installed without conflict.

Richard, was you able to use Iceberg? It should only work if either Ubuntu fix this dependency problem with libcurl or Pharo started to use libcrl4.

One thing I do find annoying in Ubuntu 18.04 is the
number of programs (like okular) that spew warning

them.  Whenever a debugger window comes up in Pharo
there is spewage on the terminal.  But it works.

I’ve had more problems with support of programming tools in 18.04, more than even Windows. I have run ‘sudo apt install’ maybe 80 times to install tools and libraries. Ubuntu 18.04’s hardware support is also lame compared to 16.04.
Personally , I’m not surprised that Pharo doesn’t run on 18.04. I stopped installing 18.04 on my new machines, after all 16.04 still has a few years of support going for it, and at least it works without hours of upgrading.

Re: What's wrong with latest Pharo?

Tim Mackinnon
Oh well - even after modifying that method and trying the remoteTypeSelector: trick it insists on giving the iceAuthenticationError - so maybe the libcurl2 install didn’t work (he said he had to install "libcurl-gnutls” to get that far).

Interestingly - my osx setup has suddenly starting giving me an IceAuthenticationError in a fresh image (I can’t imagine its related is it? Could that repo suddenly have some issue? I had the same error yesterday and had to clear out the iceberg-local). It seems that iceberg is still not quite as rock solid as we would like.

Guille - it looks like modifying that method and :
"I installed some other package (`libcurl-gnutls`) which is an "addon" to the regular `libcurl`.”

Got us further - now he’s getting IceAuthenticationError- which could be down to git vs https. (I can use the #remoteTypeSelector: trick to hopefully fix that).

When I confirm everything, I will report back the magic syntax (at least for Arch) - as well as the desire to back port that fix to 7.

Thanks for chipping in (and this is the thread that keeps on giving…)

Actually - the user has confirmed a bit more (which sounds like your hunch Guille):

Hmm… Just loading the image without `eval`ing something seems to boot up well. But then I also realise, that there is a warning:

```ioLoadModule(/opt/pharo/bin/../lib/pharo/5.0-201901231209/libgit2.so):
  libcurl-gnutls.so.4: cannot open shared object file: No such file or directory```
(edited)

So this looks like pharo tries to load a bundled libgit2 first during bootup which fails and only later, when trying to call into it, system resolves into the system installed one.
Which then causes the segfault for some reason.

I’ll see if I can guide him through changing that method.

Hi Guille - I’m not using Arch Linux myself - this was a seasoned exercism contributor trying to give pharo a spin - and sadly it hasn’t gone well (shame as they might have been an advocate) They also commented:

"I'm not quite sure though if I really want to continue from here. As someone new to pharo, I basically can't find any installation instructions that go beyond that evil `curl`. I'm happy to play this to the end with you, that at least exercism gets proper instructions, but the pharo community really should change their mind and provide more and better documentation about systemwide installation and packages. I have a hard time seeing something used at my compnay that does not provide an RPM out of the box…”

Which is fair play.

However I did get some details which might salvage something (and maybe they can try)

Its ArchLinux (apparently there are no versions in Arch, its always the latest).
Pharo wa installed via AUR (looks like a bit old - 2019-01-24 18:18) - not sure that is the issue though
AUR does give an image so they downloaded the latest 64 bit one from here - https://files.pharo.org/image/70/
Libgit2 was missing - that was installed (not clear on how - could ask)

After all of this - it did launch - they saw a welcome screen then it crashed (I think they were doing our eval string to metacello load exercism - so it would then use libgit2)

They then got this error:

I’ve pasted the error below - for prosperity.

Hi Tim,

Looking at the resolution of the libgit library, I see that in pharo7 the following:

LGitLibrary >> unixModuleName
| pluginDir |
pluginDir := Smalltalk vm binary parent.
#('libgit2.so' 'libgit2.so.0')
detect: [ :each | (pluginDir / each) exists ] 
ifFound: [ :libName | ^ libName ].

self error: 'Module not found.'

That definition may be the root of the problem in linux because it is returning the unqualified library name without the VM path.
Then, the order of resolution of libraries is the one in the operating system, which is in your case probably searching in /usr/lib or something like that.
I'd bet that you have in your system (/usr/lib/something) another libgit version but probably not matching the expected version in pharo or the architecture of pharo (32/64 bits).
Thus, pharo finds the library but cannot load it...

If you check in Pharo8, the same method reads slightly different:

LGitLibrary >> unixModuleName
| pluginDir |
pluginDir := Smalltalk vm binary parent.
#('libgit2.so' 'libgit2.so.0')
detect: [ :each | (pluginDir / each) exists ] 
ifFound: [ :libName | ^ (pluginDir / libName) fullName ].

self error: 'Module not found.'

Can you check that patching the method like that works in your case?
This maybe deserves a backporting as it may make it super complicated to work with Iceberg in some linuxes...

The error is:

No, you can't install libcurl3 with libcurl4. There is a known conflict between them: https://bugs.launchpad.net/ubuntu/+source/curl/+bug/1754294, https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=900511

Ubuntu 18.4 don't come with curl, but I think it comes with libcurl3 (I don't have means to verify it now), but when you install curl, it installs libcurl4 and removes libcurl3.

apt-cache search
reports everything it knows about, not just things that are INSTALLED.
For example, apt-cache search reports lua-curl-dev, but it is not
installed.
apt list | grep lua-curl-dev

The fact that neither libcurl3 nor libcurl4 is initially installed
means that either of them can be installed without conflict.

Installing curl don't work because there is a conflict between curl version name used on Ubuntu and that used by Pharo, you can't install libcurl 3 and libcru4 together. Ubuntu 18 comes with libcurl4 and older software depending on libcurl3 broke with it. I tested with minidebian and it also failed.

Richard, was you able to use Iceberg? It should only work if either Ubuntu fix this dependency problem with libcurl or Pharo started to use libcrl4.

I have Pharo 6.1 and Pharo 7.0 working in Ubuntu 18.04
with no trouble so far.  I just downloaded the launcher
from pharo.org and pulled the images down that way.

One thing I do find annoying in Ubuntu 18.04 is the
number of programs (like okular) that spew warning
messages out the terminal.  Pharo, sadly, is one of
them.  Whenever a debugger window comes up in Pharo
there is spewage on the terminal.  But it works.

Ubuntu 18.04 LTS is, IMHO, is royal piece of crap. Ubuntu seems to have abandoned programmers tools almost completely in 18.04. I’ve had more problems with support of programming tools in 18.04, more than even Windows. I have run ‘sudo apt install’ maybe 80 times to install tools and libraries. Ubuntu 18.04’s hardware support is also lame compared to 16.04.
Personally , I’m not surprised that Pharo doesn’t run on 18.04. I stopped installing 18.04 on my new machines, after all 16.04 still has a few years of support going for it, and at least it works without hours of upgrading.
