Ok, I think I'm almost there. I had the .pch file and had
fixed the paths and such but wasn't using the resulting
.mch file as my prefix file. So, I just took what was my
prefix file and included it into the .pch file. Prefix.h
defines ERROR_CHECK_LEVEL, includes some of my library
headers and includes PalmOS.h. The .pch file is simply
this:
#include "Prefix.h"
#pragma precompile_target "Prefix.mch"
Then I changed the prefix filename in the C/C++ Language
panel to the .mch filename. Now however, the compiler
doesn't find some #defines I made in Prefix.h.
I know I'm close. How about that last little push?
TIA,
