[Opencxx-users] Bug in OpenC++: Preprocessor Parameters Ignored!

[Marc W. <Mar...@si...>]

The following problem(s):

 - I built a compiler that should insert tracing information
   into methods (function trace). The name is: trace

 - To compile my programs, I call:
   ./trace -- -o xxx xxx.cxx

 - Now, my tracer needs the inclusion of file fntracer.hxx.
   So I compile with:
   ./trace -d-include -dfntrace.hxx -- -o xxx xxx.cxx

Problem:

The option "-include fntrace.hxx" is not passed to the 
preprocessor. If I call ./trace -DX -- -o xxx xxx.cxx, this 
is also not passed to the preprocessor, nor is any other 
option, as -I and so on.

Solution:

One possible solution: Apply my patch.

My patch does the following:

 - Add a method to get the CC options to
   OpencxxConfiguration

 - In file driver2.cc method RunPreprocessor, inserts the CC
   options after argv.push_back(compiler)

That's it.

You can find my code in "opencxx-problem.tar.gz". There will 
follow more mails on that subject later in this mailing 
list...

Please fix this problem for the next release.

Thank's
Marc
