Packaging for GNU guix

[nomike]

I'm trying to get tests running on the GNU guix package, but almost all of them fail like this:

I guess there's a dependency missing or something.

      (description
       "OpenSCAD is a software for creating solid 3D CAD objects.  It is free
software and available for Linux/UNIX, MS Windows and macOS.
Unlike most free software for creating 3D models (such as the famous
application Blender), OpenSCAD focuses on the CAD aspects rather than the
artistic aspects of 3D modeling.  Thus this might be the application you are
looking for when you are planning to create 3D models of machine parts but
probably not the tool for creating computer-animated movies.
OpenSCAD is not an interactive modeler.  Instead it is more like a 3D-compiler
that reads a script file that describes the object and renders the 3D model
from this script file.  This gives you, the designer, complete control over the
modeling process and enables you to easily change any step in the modeling
process or make designs that are defined by configurable parameters.
OpenSCAD provides two main modeling techniques: First there is constructive
solid geometry (aka CSG) and second there is extrusion of 2D outlines.  As the
data exchange format for these 2D outlines Autocad DXF files are used.  In
addition to 2D paths for extrusion it is also possible to read design
parameters from DXF files.  Besides DXF files OpenSCAD can read and create 3D
models in the STL and OFF file formats.")

Anyone has any idea about what could be wrong here?

Thanks!

I think the error comes from

https://github.com/pythonscad/pythonscad/blob/master/src/glview/OffscreenContextFactory.cc#L106
I think you should make sure, that ENABLE_GLX is set in your build.

not nice anyway that this causes a segfault

[nomike]

It is enabled already. That's what's odd.

If it's enabled and it builds alright, it should find it.

If it doesn't find it, the configure stage should fail already.

I will have a look at this later today.

[gsohler]

are you really sure that it is and is finally enabled and not turned off by CMakeLists for any reason ?
I turned it off explicitely and i exactly face your error.

[nomike]

Good point. Those CMake scripts have an odd tendency to not fail the build if crucial libraries are missing for a feature, but too disabling the feature flag which was EXPLICITLY ENABLED before. ¯_(ツ)_/¯

I will have a look when I'm back home and if that's the case I will send a patch to OpenSCAD...

[gsohler]

the crash is very likely happening in GLView.cc in teardownShader

I think this needs a lot more work.
Since pythonscad is a fork of OpenSCAD and thus the pythonscad package is inheriting most of itself from the openscad package, it's better if I get the tests of OpenSCAD to work first.

I will probably have to file a couple of tickets with OpenSCAD first and sometimes it takes time for someone to pick them up.

We'll see how fast this is.

I can link the tickets I create there here as well, if you'd like that.

[nomike]

Just cherry-picked my two shebang fixes into a PR for OpenSCAD:
openscad#5930

[nomike]

I've filed a few tickets and PRs with OpenSCAD:

• CMake warning: CMP0167 - Policy CMP0167 is not set: The FindBoost module is removed. CGAL/cgal#8914
• Fix search for HidAPI in CMake openscad/openscad#5933
• Fix: Set CMP0167 policy in CMakeLists.txt openscad/openscad#5934
• Fix search for Qt5Gamepad in CMake openscad/openscad#5935

I've also filed a ticket with CGAL, which also has an issue with CMake:

• CMake warning: CMP0167 - Policy CMP0167 is not set: The FindBoost module is removed. CGAL/cgal#8914

But that was nothing serious yet.

I'm getting to the sauce now I guess.

[nomike]

I'm done with fixing up the openscad guix package. It builds with the latest commit and all tests are green.
I'm now continuing to get pythonscad to build correctly and have noticed a few things:

In CMakeList.txt there is this code block:

    #    if (${OPENCSG_VERSION_STRING} VERSION_LESS "1.6.0")
      set(OPENCSG_GLEW ON)
      target_compile_definitions(OpenSCAD PRIVATE OPENCSG_GLEW)
      #endif()

In OpenSCAD the if is not commented out though.

I've compiled both OpenSCAD and PythonSCAD and ran one of the tests (preview-

manifold_issue4432) with strace with OpenSCAD and PythonSCAD and manually compared the two straces, after normalizing all addresses in the strace.

openscad.strace.gz
pythonscad.strace.gz

Most differences were easy to explain (e.g. OpenSCAD doesn't use libcurl or libjpeg) or resulted from different ordering.

But what stuck out was that PythonSCAD did this:

pythonscad.strace:openat(AT_FDCWD, "glibc-hwcaps/x86-64-v2/libGLEW.so.2.2", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
pythonscad.strace:openat(AT_FDCWD, "libGLEW.so.2.2", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)

whereas PythonSCAD does not.

As OpenCSG is at version 1.8.1 these two CMake directives are run for PythonSCAD and not for OpenSCAD:

      set(OPENCSG_GLEW ON)
      target_compile_definitions(OpenSCAD PRIVATE OPENCSG_GLEW)

This clearly explains the GLX error PythonSCAD is producing.

To prove this theory I added a patch to the guix package definition of PythonSCAD to un-comment that if, restoring the behavior of OpenSCAD.
However, if I do that the build fails with the following error:

And that's where I'm a bit stuck now.

Any ideas of how to further track down this issue?

[nomike]

@gsohler can you please try to build PythonSCAD with the following patch applied?

And if you get the same error message, we need to figure out how to fix the build with this patch applied. Because I pretty much think that this would fix the build on guix.

Another option would perhaps be to get GLEW running, but that seems to be more complicated.

I'm way to unfamiliar with OpenSCAD/PythonSCAD and GLEW to solve this I'm afraid...

[gsohler]

I have removed the Texture Feature from the code because it does not work anymore, anyway
Also libjpeg is not needed anymore and is removed.

This allows me to compile pythonscad successfully with and without

set(OPENCSG_GLEW ON)
target_compile_definitions(OpenSCAD PRIVATE OPENCSG_GLEW)

also the issue4432 ctests are pass in either way.

Hope this brings us forward.

A few of them failed as they expect the build to happen in ./source/build/. But guix defaults to an out-of-source build.

I managed to get those working by patching the expected files of these tests. This fix will just work for guix, but that's currently the only place where this issue exists, so it doesn't matter.

For the other failed tests I will open separate issues as they might have different root causes. And otherwise I will lose overview quite quickly ;-).
