Title: View source code output from pre-processor?
Post by: PhilG57 on September 14, 2010, 12:50:46 AM

I'd like to see the C source code produced by the preprocessor after it has read my source file and resolved the macros, #defines, etc.  Is this possible???

Thanks.

From PellesC help or commandline:

/E Runs the preprocessor only (to stdout).

Code: [Select]

Thanks.  I could not get the /Fo to create an output file I could later view but I was able to wade through the listing provided in the 'Project' window of the compiler.  Thanks again.

Use option:
/P                 Preprocess only (to srcfile.i)
