I'm trying to get FreeCAD back in shape on Fedora[1] and what I hope is the last problem is that it's still building against the Python2 library (because it's default). I can override the behavior by specifying "-DPYTHON_SUFFIX=<python3 SOABI> but it's different for every arch...
$ python3
Python 3.7.3 (default, Mar 27 2019, 13:41:07)
[GCC 8.3.1 20190223 (Red Hat 8.3.1-2)] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import sysconfig
>>> sysconfig.get_config_var('SOABI')
'cpython-37m-x86_64-linux-gnu'
I cobbled this together for the spec file but it may need work:
$ python3
Python 3.7.3 (default, Mar 27 2019, 13:41:07)
[GCC 8.3.1 20190223 (Red Hat 8.3.1-2)] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import sysconfig
>>> sysconfig.get_config_var('SOABI')
'cpython-37m-x86_64-linux-gnu'
I cobbled this together for the spec file but it may need work:
%define py_suffix %(%{__python3} -c 'import sysconfig; sysconfig.get_config_var("SOABI")')
The weird part is that it's evaluating as blank on Fedora 29 and 30[2] and working in Rawhide EXCEPT for armv7hl in which it's evaluating to[3]:
-DPYTHON_SUFFIX=.cpython-37m-armv7hl-linux-gnu
But the shiboken config file is named:
/usr/lib/cmake/Shiboken-1.2.4/ShibokenConfig.cpython-37m-arm-linux-gnueabi.cmake
Which is very different...
The best answer is probably to rebuild shiboken with Python3 being the default but there should be a way to predict what the python3 SOABI naming scheme will be...
Thanks,
Richard
