# We want to byte-compile the .py files within the packages using the new

#
# Unfortunately, rpmbuild's infrastructure requires us to jump through some
# hoops to avoid byte-compiling with the system python version:
#   /usr/lib/rpm/redhat/macros sets up build policy that (amongst other things)
# defines __os_install_post.  In particular, "brp-python-bytecompile" is
# invoked without an argument thus using the wrong version of python3
# (/usr/bin/python3.6, rather than the freshly built python3), thus leading to
# numerous syntax errors, and incorrect magic numbers in the .pyc files.  We
# thus override __os_install_post to avoid invoking this script:
%global __os_install_post /usr/lib/rpm/brp-compress \
  %{!?__debug_package:/usr/lib/rpm/brp-strip %{__strip}} \
  /usr/lib/rpm/brp-strip-static-archive %{__strip} \
  /usr/lib/rpm/brp-strip-comment-note %{__strip} %{__objdump} \
  /usr/lib/rpm/brp-python-hardlink
# to remove the invocation of brp-python-bytecompile, whilst keeping the
# invocation of brp-python-hardlink (since this should still work for python3
# pyc files)

# For multilib support, files that are different between 32- and 64-bit arches
# need different filenames. Use "64" or "32" according to the word size.
# Currently, the best way to determine an architecture's word size happens to
# be checking %%{_lib}.
