First comment is on the Makefile, in particular for cross-compiler.
It would be nice if all of the tools used the following:
CC = ${CROSS_COMPILE}gcc
and similarly for CPP, STRIP, AR, and RANLIB.
For me, I would then be able to do:
make CROSS_COMPILE=arm-linux-
(using CROSS_COMPILE in that particular way is fairly common in the
linux world).
Also CPPFLAGS is normally used for C pre-processor flags, and CXXFLAGS
is normally used for C++ flags. CFLAGS And CXXFLAGS should both
include CPPFLAGS (so that -I can be specified). So CPP would actually
be called CXX.
Variables like CFLAGS (and CPPFLAGS and CXXFLAGS) should normall use
+= rather than = so that additional options can be specified on the
make invocation.
Now that I've installed jpeg, I got everything to compile. I'll take a
close look at the actual code later.
Thanks
