Cannot find some headers
Opened this issue · 2 comments
I'm trying to update the flatpak package of this, but the build fails with Cannot find python library method Py_Exit. Any idea which library/dependency provides this function?
I modified this to python3.10:
scons: Reading SConscript files ...
3.10.11 (main, Jul 19 2023, 08:34:57) [GCC 12.2.0]
Using options in scons/flatpak_options.py.
Got git revision 1658965877

Looks like it is defined here https://github.com/python/cpython/blob/832c37d42a395d4ea45994daffa5e41bd74ac1bb/Include/pylifecycle.h#L30
But that header is included in the package. Any idea why it can't find it?
Ok this seems to fixed by adding a pythonlibname='python3.10'
But now it can't find some headers again even though they are installed:

1st issue is numpy/ndarrayobject.h this is in /app/lib/python3.10/site-packages/numpy/core/include/numpy/ndarrayobject.h. My guess is that it is looking in the wrong place?
2nd issue is ncVar.h which is in /app/include/ncVar.h not sure why it can't find it?. Try setting the netcdf_libs variable, didn't work.
