Arch Linux User Repository

I added it

Looks like the make dependency glslang is missing:

meson.build:648:15: ERROR: Program 'glslangValidator' not found or not executable

yes, added python-yaml, sphinx is only used for the doc

Further Python makedepends are missing. It makes probably most sense if you have a look at the regular package when updating, e.g. https://gitlab.archlinux.org/archlinux/packaging/packages/mesa/-/commit/0e47b98b859e1e5b98ae48af1e0236b226eb7f1f shows the new dependencies as of 24.2.

The build succeeds when adding python-packaging as make dependency. Considering it was used just internally by meson to check for another dependency we might want to add it to mingw-w64-meson. On the other hand, the regular mesa package also lists python-packaging directly.

I had a look at the log file meson wrote:

Running command: /usr/bin/python3 -c '
try:
  from packaging.version import Version
except:
  from distutils.version import StrictVersion as Version
import mako
assert Version(mako.__version__) >= Version("0.8.0")
  '
--- stdout ---

--- stderr ---
Traceback (most recent call last):
  File "<string>", line 3, in <module>
ModuleNotFoundError: No module named 'packaging'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "<string>", line 5, in <module>
ModuleNotFoundError: No module named 'distutils'

After installing python-packaging I can rerun the command just fine. I'll try the build again with python-packaging as make dependency.

I'm building this in a clean chroot. Only Python packages pulled in as dependencies by pacman are installed. I don't set any of the variables and no Python modules are installed outside of pacman. I also ran the command in the build env:

[root@arch-nspawn-408392 /]# python -c "import mako; print(mako.__version__)"
1.3.5

what does this line give ?

python -c "import mako; print(mako.--version--)"

(replace - with _)

any conflicting python packages installed in ~/.local ?

is PYTHONPATH or PYTHONHOME set ?

For some reason the build keeps failing for me:

The dependency is not missing and python-mako-1.3.5-1 is installed correctly into the build root. So I'm not sure why it cannot find it.

I forgot about the directx-headers dependency
