Hi, I built Overture successfully, but while compiling CG, I get errors.

I know that some compilers restrict the declaration of a loop counter variable to within that loop (ie. for (int i=0;… ) { do this } to within the “do this” loop), so am I missing some flag here? Or does the latest g++ compilers not allow this anymore?
