Check Makefile.cfg and set the variables in there if things dont work.
This compiles with no warnings at all with the default options on
Redhat 6.2 / Linux-2.2.16 with glibc6 and the pre-installed libjpeg,
libpng, libtiff, and libz libraries that were already installed in my
/usr/lib directory.
I tested the GTK example I wrote under X11R6 running 1024x768x24bit but
the machine I was using does not allow switching to other modes, so
I am unsure if the picture would be displayed properly in other video
modes.
You should be able to link progams with the -lfreeimage options after
it is compiled and installed, which will require that libjpeg, libpng,
libtiff, and libz are installed as well.  If you statically link with
libfreeimage.a you must also link with libjpeg.a, libpng.a, libtiff.a,
and libz.a.
If you unzip a new snapshot over old code, it will need to be reran
thru dos2unix to strip the CR's from it.  `make refix` or just
rm .nodos2unix yourself to allow make to rerun dos2unix next time
the library is build.
Please let me know how this works for you under Linux or any other *nix
