# problem: libstdc++ is _not_ forwards compatible, so if we try to compile mod
# files on a system that ships a version of it older than the one used for
# building the wheel itself, we'll get linker errors.
# solution: use a well-defined oldest-supported version of GCC
# we need to do this _before_ building any libraries from source

# NOTE: NMODL transpiler is used in during build step but it requires
# sympy+python available in order to translate MOD files to C++. But under
# manylinux container, Python (libpython) is not available and hence we can't
# complete the build step. In order to enable building wheels with the existing
# implementation of NMODL, for now, we are making libpython available inside
# the manylinux container which is just used during the build step (nothing is
# linked to libraries or binaries of distribution).
