[GRASSLIST:2770] Re: compiling grass and gd includes

Glynn,

Thanks for all the help. I hope our discussion is also helping other 
trying to compile GRASS. I think this should about do it (fingers 
crossed). I have a couple of interesting issues with freetype and gdal 
mentioned below.

I should also mention that I am using the WONDERFUL fink utility and 
service for installing many of my unix packages. GRASS is currently in 
their CVS submission tracker for inclusion in the OS X/Darwin ports that 
fink supports (my suggestion). When complete, it will build from the 
source. Unfortunately, I have been unable to get PostgreSQL to compile 
and install correctly either from the source, or via fink (also source 
file with patches to the configure script). I anyone out there has been 
successful in getting PostgreSQL on a Mac OSX system, I'd love to hear 
about it.

I have all this stuff (including all the header files). However, 
ft2build.h is in the /sw/include directory instead of the 
/sw/include/freetype2 directory. I will cp ft2build.h to 
/sw/include/freetype2 and try the configure again.

These didn't come with the package...only the dylib.

I would like to have r.in.gdal. I'll check the head file as you suggest. 
Interestingly, I am running r.in.gdal on the precompiled Mac OSX binary 
with only the gdal dylib. I had to change my login shell script to set 
the DYLD_LIBRARY_PATH environment variable, but that was it. Maybe I 
should let it compile without linking to gdal and not worry about it???
