Arch Linux User Repository

From official GNOME docs:

"Attention: PyGTK 2.24 will be the last release in the PyGTK series and will support the full GTK-2-24 API. PyGTK should not be used for new projects and existing PyGTK applications are recommended to be ported to PyGObject. See here for more information."

https://wiki.gnome.org/Projects/PyGTK/WhatsNew224

Please stop asking me to update this package. I only "keep" it, so that it is not messed with by others, as some older applications still rely on it to function.

Thank you.

@micwoj92 Ah, thank you, I understand. I will look into fixing that.

This is because in order for the to become "optdepends" they need to be present at compile time.

If you compile pygtk, then install libglade and/or python2-numpy you will not get anything extra and will have to recompile pygtk. This is not how software is packaged for Arch Linux.

@patlefort I'm not sure I understand. The README on the PyGTK archive repo lists gtk2, libglade and numpy as optional dependencies, and the package compiles without any of them installed.

gtk2 is indeed missing entirely, so I should at least add that to optdepends, but I'm wondering what you mean by "required at compile time". In what way are they required?

--- https://gitlab.gnome.org/Archive/pygtk/-/blob/master/README

Requirements

• C compiler (GCC, MSVC and mingw supported)
• Python 2.3.5 or higher
• PyGObject 2.21.3 or higher
• Pycairo 1.0.2 or higher
• Glib 2.8.0 or higher
• GTK+ 2.8.0 or higher (optional) or GTK+ 2.10.0 or higher for 2.10 API [...] GTK+ 2.22.0 or higher for 2.22 API GTK+ 2.24.0 or higher for 2.24 API
• libglade 2.5.0 or higher (optional)
• pycairo 1.0.2 or higher (optional)
• numpy (optional)

Missing gtk2 in dependencies. Also both optdepends shouldn't be optional since they are required at compile time.

Okay, I applied -fpermissive. I also fixed the license identifier to be SPDX-compliant (thank you @HurricanePootis again for the suggestion), and removed some (hopefully) unnecessary dependencies. I tried to build in a clean chroot, but I'm very tired and didn't want to wrangle python2 dependencies so I gave up. Let me know if you experience any issues.

Hi all. I will get around to resolving this issue soon.

It seems that GCC14 upgraded some warnings into errors, namely -Wint-conversion and -Wimplicit-function-declaration. https://gcc.gnu.org/gcc-14/porting_to.html#warnings-as-errors

The article above does indeed suggest to use -fpermissive for old code, so that's what I'll do, rather than patching the source to fix the issue directly or using GCC13. Thank you @HurricanePootis for the suggestion.

Hello, I have fixed compilation of this package

The flag -fpermissive needs to be added to the cflags and cxxflags.

Same issue, source code which pygtk is built from is probably outdated, and needs to be fixed.

I have the same issues building it with gcc14 =\

Fails to build due to changes in gcc14:
