Packaging for guix

Packaging for guix

[John Soo]

Hello pyside maintainers,

Hope you are all well.  I am looking to package freecad for the guix package manager for which pyside is a dependency. I’m having some trouble packaging pyside as the build and environment for guix (like nix) are quite different from a Debian style system. There a quite a few differences:

 -  the prefix for installation directories is in a unique directory specific to the package
 - cmake and python require many particular environment variables and flags
- library and linking paths are very different and often source shebangs and linking paths need to be patched to point to the correct paths
 - the build process happens in an isolated build environment apart from any system directories
 - probably more that I haven’t come across yet

I’ve tried using the provided python build process but I get several build errors, let alone runtime issues. Would anyone be able to point me in a direction to patch pyside for such a packaging system? Currently I’m stuck building Shiboken. I’d particularly like guidance on how to setup cmake to build it correctly (mostly the ability to provide our particular flags and variables). Any help would be greatly appreciated.

Thank you,

John

Could you show us the package definition you have so far?  Can you also
show us what errors you get?

Hi Ricardo,

Thanks.  I've been hacking in my channel and master usually has my current
work: https://github.com/jsoo1/guix-channel/blob/master/python-pyside.scm -
current commit is 59f6da3.
<https://github.com/jsoo1/guix-channel/commit/59f6da338ceab793be5c81407e46cd03424b8ae7>
Aside
- I would like to patch most of the working and compatible packages in the
channel back into guix, but freecad has been taking all my guix hacking
time.  I've attached the build log since there are some errors building
both the apiextractor package and the shiboken library.  Note that
python-pyside.scm includes work on version 1 of the Shiboken library. That
build seemed ok but freecad is moving to pyside2.  I followed nix's
strategy of building the packages separately and using cmake-build-system
instead of python (
https://github.com/NixOS/nixpkgs/blob/2d656a9729739e8ca5486058a76669d0ea4442df/pkgs/development/python-modules/pyside/shiboken.nix#L33)
for version 1. Pyside 2 is bundled into a single repository so I am not
sure I can do the same thing for it. Thanks again!

- John

Hello John,

I'm not familiar with guix, but if the CMake approach doesn't work [1]
and the setuptools also doesn't work [2],
maybe you can share some of the logs related the build errors
so we can see how what's precisely the issue.

Cheers

Hi Cristián,

Thank you! I have been following the cmake path and it seems to be working
better than before. If I find more issues, I will ask.  Thanks again!

Hi Cristián and Ricardo,

A quick update: Shiboken2 builds! Thanks for your guidance!  I may have
more questions when building freecad itself, but this was very helpful.
Thanks again!

Hi again PySide and Guix maintainers,

Thanks for your help so far. After building Shiboken2, Pyside2 and
PySide2-Tools are still required for FreeCAD. In building Pyside2, I get
the error in the attached paste. Clang 6.0.1 and LLVM 6.0.1 are installed
and I have set the CLANG_INSTALL_DIR and LLVM_INSTALL_DIR vars to their
respective paths.  I have also included the package definition in the paste
for the Guix maintainers, if they have any input.

https://paste.debian.net/1081332/

There also seem to be some more issues finding various extra QT libraries
but I'd like to do one thing at a time.

Thanks again for all your help!

- John
