Title: Conditional Compilation in C++ Reverse Eng.
Post by: Martin Wawro on August 20, 2012, 07:07:22 pm

Hi,

I am working at a multi-platform project and I basically want to generate models from C++ sources for a special platform. The platform-specific stuff is usually put in conditionals (#ifdef). It seems that EA ignores them (seems they always evaluate to true).

Is there any way to teach EA not to consider code in #ifdefs ?

A workaround that MAY get you over the line..

Use your C++ compiler to output pre-processed source code.  You should then be able to reverse engineer the resulting source code using the standard mechanism and (hopefully!) get the results you're after.

Yes, this is the workaround I also had in mind. It would have been nice though if EA would support this out of the box. Pity.

It can be done, but it's not trivial enough to explain here. Contact sparx support and they'll be able to help you.

I wonder if the explanation could be placed into a white paper if it is too complex. I suggest that many users have the same problem. :-?
