MacOXS undefined symbols error

[nachiket]

Hi -- I'm trying to get gcc-python-plugin to work on MacOSX. I am facing the following issues with gcc-8

gcc-8 -I/usr/local/Cellar/gcc@8/8.3.0_2/lib/gcc/8/gcc/x86_64-apple-darwin19/8.3.0/plugin/include -I/usr/local/Cellar/gcc@8/8.3.0_2/lib/gcc/8/gcc/x86_64-apple-darwin19/8.3.0/plugin/include/c-family -I. -I/usr/local/include -O2 -Werror -g -fPIC -fno-strict-aliasing -Wall  -shared gcc-callgraph.o gcc-cfg.o gcc-constant.o gcc-declaration.o gcc-diagnostics.o gcc-function.o gcc-gimple.o gcc-location.o gcc-option.o gcc-rtl.o gcc-tree.o gcc-type.o gcc-variable.o autogenerated-casts.o -o libgcc-c-api.so -lstdc++

I am not sure if I'm missing any shared library path. I did have to add /usr/local/include to get some errors with missing gmp.h sorted out. I tried adding /usr/local/lib to LDFLAGS to no effect.

@nachiket did you succeed to build on MacOS? According to the README this module depends on gcc-plugin-devel but I don't think this is available in Mac. At least brew does not show it.

I wasn’t able to build it. It did with in Ubuntu at some point by I haven’t checked recently.
