That's not how you do it. The build system will build the collection of 
libraries for the other GCC version automatically as part of the 
process. But for this to work you have to actually enable inclusion of 
those. The --alternative switch will only tell it where to put them 
when compiled, not to actually compile them. For this you need to add


To your UserBuildConfig. Then a zip including the libraries for the 
other GCC version will be built and extracted to the installation. You 
then compile either in the generated directory for GCC2 to build a GCC2 
base with GCC4 alternative libraries or you build in the generated 
directory for GCC4 to build a GCC4 base with GCC2 alternative libraries
