I am updating my pkgsrc entry, and I ran into a problem when I want to
enable the JPEG option. I'm still looking for the right thing to patch,
but here is a thing to clean up.
I think many of the assignments in the Imakefile should use ?= instead
of =, so that they can usefully be set from the Imakefile.local.
I think I need this to get proper support for e.g. the JPEG option,
where I need to pass long -I -L and -rpath options to find it. So I'd
like something like this:
#ifdef JPEG
JPEGLIBDIR ?=
JPEGINCDIR ?=
JPEGDEFINES ?= -DJPEG
JPEGLIB ?= $(JPEGLIBDIR) -ljpeg
#else
JPEGLIB =
JPEGLIBDIR =
JPEGINCDIR =
JPEGDEFINES =
#endif
so that my Imakefile.local file can contain something like this:
JPEGLIBDIR = -L/usr/pkg/packages/jpeg-6bnb2/lib
-Wl,-rpath,/usr/pkg/packages/jpeg-6bnb2/lib
JPEGINCDIR = -I/usr/pkg/packages/jpeg-6bnb2/include
I haven't exactly decided how to pass these options, but having the ?=
in place will certainly help.
Cheers,
-Olaf.
