Hello everybody, now that i know and compiled with success gcc, i wonder how i can make a gcc compiler for 64 bits platform, is the compiliation process is the same except that extras flags are involved, and if yes, which ? i've looked on the net for binutils i found --enable-64-bit-bfd, --host=x86_64-mingw32 and also for --target is there any other flags for gcc dependencies ( like gmp, mpfr, mpc, pthread ... ) ? Thanks for all. Sam.
