Building on Mac OS X 11.0 with python 3.6.5 problem with linker flags

[georgid]

Hey, I am building with
/Users/joro/.pyenv/shims/python ./waf configure --with-python --pythondir=/Users/joro/.pyenv/versions/my_virtual_env/lib/python3.6/site-packages

and failed with

err: ld: -stack_size option can only be used when linking a main executable
clang: error: linker command failed with exit code 1 (use -v to see invocation)

According to this post and this post the flags -Wl,-stack_size,1000000 are confusing the linker. Is there a way to tell ./waf or to tell python3-config --ldflags to exclude these flags?

It seems that the problem is that the ld flags are populated from the python installation used. You can check them with /path/to/python/bin/python3-config --ldflags
It seems that when using a framework build (from brew or binary ) the ldflags do not contain the problematic -stack_size.
Otherwise using non-framework python (from pyenv or anaconda) they ldflags seem to be there.

If using the latter, a workaround would be to tweak the ctx.env.LDFLAGS in wscript for waf, which is where they are stored at compile time. However, I could not make it work. Check this kovidgoyal/kitty#289
