[erlang-questions] Compiling R16B on Mac OS X Mountain Lion

[Patrik Nyblom]

Hi!

You should not need the macports PCRE lib, there's an erlang specific 
version in the distribution. Remove (unset) LDFLAGS and CPPFLAGS, clean 
and build again.

Also it seems your error does not correspond to your configure flags, 
the gcc command line includes -m32, but you have specified 
--enable-darwin-64bit, so it should read gcc -m64. Strange.

Try the simplest, use default compiler and no configure flags (and no 
flags in environment) and then move forward from there.

Cheers,
/Patrik
