ld: symbol(s) not found for architecture x86_64
I've included $(python_includespec) in my Makefile:
override CPPFLAGS := $(python_includespec) $(CPPFLAGS)
Is there some other magic I need? Do I need to switch to using
MODULE_big or something?
After some Screwing Around(TM), I figured out that the magic trick is to
add the output of python-config --ldflags to LDFLAGS. I see we have a
$(perl_embed_ldflags), should there be something similar for python?
