Actually, the version doesn't matter except it should be greater than 4.8. I've already read https://gcc.gnu.org/wiki/FAQ#configure_suffix but actually there is no answer for my case since I do have mpc, gmp and mpfr installed (correctly at least as make check claimed for each of these three). If it didn't find some libs, I understand that I would have checked the option --with-... and check the paths but now it seems like installing one of the internal (for gcc) packages stdc++ failed. So, you recommend to install mpc, gmp and mpfr once again using prerequisites? > On 8 August 2014 10:56, Jonathan Wakely wrote: >> On 8 August 2014 10:54, Kirill Voronin wrote: >>> >>> I'm trying to build gcc 4.9.0 for linux (OS Red Hat, very old version). > > Also, any reason why you are not using 4.9.1 instead? > >>> I've installed manually mpc, gmp and mpfr before running ./configure >>> >>> Configure line: >>> ../gcc-4.9.0/configure --prefix=/usr/new/gcc_install --enable-shared >>> --with-gmp=/usr/new/gmp_install --with-mpfr=/usr/new/mpfc_install >>> --with-mpc=/usr/new/mpc_install >>> >>> and it works fine. >>> >>> But then I tried to make and got the following error: >>> >>> checking for suffix of object files... configure: error: in >>> `/ifs/home/icmmg/voronin/pardiso_proekt/pardiso_project/new/gcc_dir/x86_64-unknown-linux-gnu/libgcc': >>> configure: error: cannot compute suffix of object files: cannot compile >> >> https://gcc.gnu.org/wiki/FAQ#configure_suffix >> >> Follow http://gcc.gnu.org/wiki/InstallingGCC > > Specifically, do not install GMP, MPFR and MPC separately, use the > download_prerequisites script. > --
