Find ffi.h outside of /usr/include

[flwyd]

The MacPorts distribution of yabasic fails in the configure step because configure can't find libffi. MacPorts installs everything in /opt/local and ffi.h in particular is in /opt/local/lib/libffi-3.2.1/include.

I can get yabasic to install by configuring the Portfile to pass --disable-use-ffi to configure. However, it would be nice if configure could locate the libffi installation and pass it as a -I parameter to the compiler. Two standard ways to handle this:

1. Accept a --with-libffi=/path/to/ffi argument to configure. (Some packages have --with-ffi-include and --with-ffi-lib for separate -I and -L paths.)
2. If pkg-config is present, call pkg-config --cflags libffi and pkg-config --libs libffi and pass the results through to the Makefile.

Hi Trevor,  thanx I will look into this ! Generally speaking, I am interested in a standard way to support yabasic on a Mac (without having a Mac myself ...). So your mail is very welcome and I will try to add those switches.

Hi Trevor, thanx for suggesting pkg-config ! Version 2.86.7 uses it and its configure now has a switch --with-ffi . Could you please give it a try (tar-file attached) ? regards Marc

If I understand Trevor correctly (private communication), this is fixed with a small mod he suggested and which I included in configure.ac.

yabasic 2.86.8 has another small change in this area, so I am leaving this open for another while ...
