[quote user="ReinierC"]I am using CCS 5.5 (C6000 codegen tools v7.6.0) for building our project, which consist of a main executable project and 15 dependent static libraries.[/quote]
If there are 15+ projects being rebuilt each time, I wouldn't consider 3-4 minutes as excessively long ( it depends on the size of the projects, of course). Do you already have parallel builds enabled?
If building from command line is an option for you, that could potentially be faster and avoid some of the overhead that comes with the CCS GUI.
