pkg-config v. -I/opt/local/include

[Craig Treleaven]

Hi:

I’m having buiild failures due to includes pointing to old/other headers installed in /opt/local/include.

As I understand it, 'pig-config —cflags’ returns an empty string when a header is installed in /usr/include.  The port I’m working on, MythTV 0.28-pre, uses pkg-config to check for several dependencies.  Under MacPorts, I end up with '-I/opt/local/include’ early in the compiler arguments and thus picks up old or unintended versions of headers.  Under Linux, no problem.

Is there some way I can coerce pkg-config to treat /opt/local/include like it does /usr/include?  I’ve looked at the man page for pkg-config and tried using some of the environment variables but without success.

Eg, with MacPorts:
$ pkg-config --cflags x264
-I/opt/local/include                     ## want to make this disappear!

is there a magic recipe?

Thanks,

Craig
