I am trying to build gcc 4.8.0 and am confused by the prer= equisites. What are the recommended versions of cloog/ppl/isl (+gmp/mpfr/mp= c). Is libiconv needed? What is the required version of systemap? Can the p= rerequisites be moved inside the gcc source once the gcc source is untarred= or do they have to be kept separate and compiled separately?
