Problem with PharoLauncher on Ubuntu 18.04 (64 bit)

Hi all,

I was using the PharoLauncher (32 bits) version on Ubuntu 14.04 (32 bits)
without problem. But two days ago I installed Ubuntu 18.04 (64 bits) and
tried to run PharoLauncher-linux-1.1-x64 and when I tried to run a 6.1 image
I got this message.

Try this on a terminal:

cd "/home/francisco/Pharo/vms/private/6521" && export SQUEAK_PLUGINS="" &&
"/home/francisco/Pharo/vms/private/6521/pharo" --nodisplay
"/home/francisco/Pharo/images/Pharo 6.1 (stable)_1/Pharo 6.1
(stable)_1.image" eval "(Smalltalk imagePath asFileReference parent) /
'pharo.version' writeStreamDo: [ :stream | |major minor|major :=
SystemVersion current major.minor := SystemVersion current minor.(major = 6
and: [ SystemVersion current highestUpdate >= 60509 ])ifTrue: [ minor := 1
].stream << major asString;<< minor asString ]"

And got this:

Error. Could not determine platform's libc path for VM.
Try forcing $PLATFORMLIBDIR in /home/francisco/Pharo/vms/private/6521/pharo,
based on LIBC_SO.
Please report what works to pharo [vm-dev] mail list.

  System seems to be 64 bit. You may need to (re)install the 32-bit
libraries.

Do I really need to install 32-bit libraries ?

Any advice will be apreciated !!!

Thanks in advance,

Francisco

Hi Francisco,

Prepare 64-bit-Linux for 32bit Pharo

The installation in Debian 8 Jessie 64bits and Ubuntu 14.04 and Later require some operations.

 sudo dpkg --add-architecture i386 

 sudo apt-get update 

 sudo apt-get install libx11-6:i386 

 sudo apt-get install libgl1-mesa-glx:i386 

 sudo apt-get install libfontconfig1:i386 

 sudo apt-get install libssl1.0.0:i386

It is not very surprising that you get problems when using 32-bits pharo
version on an new 64-bits system. With time, it is more and more difficult
to find compatible 32-bits libraries to install on these systems.
Did you follow instructions available at
https://pharo.org/gnu-linux-installation?

Hi Christophe,

Thank you for your prrompt reply.

Before I had a 32 bit PharoLauncher running on a 32 bit Ubuntu without
problem and now I do not have a 32 bit of PharoLauncher running on a Ubuntu
18.04.

But now I have installed an all new  64 bit version of Ubuntu 18.04 and then
decompressed the PharoLauncher-linux-1.1-x64.zip and is with this version
that I have problems to run a 6.1 image.

I think the problem would be that PharoLauncher doesn't locate the path of
libc.so

"Error. Could not determine platform's libc path for VM.
Try forcing $PLATFORMLIBDIR in /home/francisco/Pharo/vms/private/6521/pharo,
based on LIBC_SO."

But I don't know how to fix it. I will try to post the issue at
https://github.com/pharo-project/pharo-launcher/issues

Best regards.

Francisco

Hi Francisco,

I now get your problem.
You tried to run a Pharo 6.1 32-bits image that requires a 32-bit VM on a 64-bit system. It is doable but to do that, you first need to install 32-bit libraries required by Pharo VM.
If you do not want to do that, you could simply try to use a 64-bit version of Pharo 6.1.

Next Pharo Launcher version will come with a more detailed information on images (32 or 64 bits). I will also try to add a warning when trying to run a 32-bit image on a 64-bit system.
