I am trying to develop a block-diagramming / cross-refererncing GUI tool
for C projects’ code so that people can block-diagram the code of a
project and then conveniently see the code flow. I have found that if I
am to maintain or contribute to a 100 KLOC+ project, block-diagramming
and cross-referencing helps. The tool is being developed in PhAB (the
GUI). To build and walk the C tree I am using a component written by
someone else - this component has compiled with gcc 2.95 on FreeBSD and
worked properly and also on Linux and NetBSD. I have managed to compile
the code on QNX but when I execute it it craps out on cpp. Below are the
reported errors:

If the source code walked does not have for example #include <stdio.h>
which in turn includes platform.h and in turn _pack64.h and _packpop.h
→ everything works fine.
I have tried posting to the inn.qnx.com newsgroups but noone seems to
read those? Anyone knows how I can get in touch with QNX people willing
to help out?

The problem is that there are some defines that are set by the compiler,
and the includes rely on these for doing system/compiler specific stuff.
If you try
gcc -v -E ctree.c 1>/dev/null
you’ll see all the defines you need ctree to pass to cpp. Most of those
are set by the gcc specs file, /usr/lib/gcc-lib/ntox86/2.95.2/specs
You should not be calling cpp directly but instead cc, gcc or qcc.
Each of these front ends setups symbols that header files needs
to support various features.

gcc -E helped. Everything works now. Thank you all and sorry for asking before thinking
Best regards,
