Pharo7 stock image shows a blank desktop in 64b (NixOS Linux)

Hi,

I'm having difficulties running Pharo7 on a 64b VM compiled from
sources, in NixOS.
The VM gets built successfully, but when I open a Pharo7 image I only
get the uppermost menu, and a blank desktop. If I try to quit, I get a
grey rectangle.
I've added all runtime dependencies I found missing when running it with
strace.
I saw it working once, but had to rebuild it to add a missing
dependency, and afterwards I've been trying with different gcc versions
and couldn't make it work again.
Additionally, I recall that when it worked, it complaint about not being
able to find the stdout file descriptor.

Any ideas about where I should be looking at? I'm out of ideas.

Kind regards.

Hi,

Sorry, I wasn't aware my previous mail was sent as html.
I thought it was Pharo7 related, but it doesn't seem to depend on the
version of the Pharo image. It happens with Pharo 6.1, Pharo 7, and
Pharo 8 (screenshots attached after I try to close the image).
I'm just looking for any hint about where to focus. I'll try to follow
the path Morphic -> primitive -> vm.
No errors or warnings logged to stdout.
No fonts, no window decorations, no window contents.
It seems as if the VM wasn't aware of any issue, so I'd guess it has to
do with the X11 display driver.
If I start the image with --xshm I get a black rectangle in the middle.

Any hints about what could be causing Morphic UI elements not rendering
as expected?

Any suggestions would be appreciated.

Re: Pharo7 stock image shows a blank desktop in 64b (NixOS Linux)

I've really no clue, but btw, are you building a VM completely from scratch

or are you using this as a basis... https://github.com/NixOS/nixpkgs/tree/master/pkgs/development/pharo

What windowing system are you using versus the windowing system on a distribution where Pharo works?

Re: Pharo7 stock image shows a blank desktop in 64b (NixOS Linux)

Hi,

I'm using the Nix package you mentioned, but in fact it's building the
VM from scratch.
If you take a look at the "derivation" (Nix jargon), you can see that it
builds the VM using the standard autotools, plus:

- The configure phase uses these modifiers: --without-npsqueak
--with-vmversion=5.0
- The make phase phase uses these CFLAGS: -DPharoVM -DIMMUTABILITY=1
-msse2 -D_GNU_SOURCE -DCOGMTVM=0 -g -O2 -DNDEBUG -DDEBUGVM=0 and
LDFLAGS: -Wl,-z,now
- Uses the plugins.{ext,int} from cog.spur folder, verbatim.

The dependencies are the ones in the list at the beginning of the file,
and the "libs" variables in the "installPhase".

However, I'll try that same package now that my "blank" desktop problem
reproduces also in Pharo6 images. At first, I thought it was
Pharo7-specific.
I'm using tag pharo7.0.0 [2] of github's opensmalltalk/opensmalltalk-vm.
Could that be an issue? Should I use a different branch?

Thanks!

That should be the tag to run a Pharo 7 image,

but above I see `--with-vmversion=5.0` and not sure the impact of that.

Mostly the VMs are backward compatible, so unless someone advises of a specific counter-case

Pharo7.0.0 VM should run Pharo 6 Images.

What is the last VM/Image you saw working on Nix?

You might need to bisect from there. I'd keep the Image the same while you move the VM forward.
