I'm attempting to install gcc 4.3.6 on RHEL 5.5 x86_64 using the installed (default, from Redhat) gcc version 4.1.2. Everything [except the `make install`] appears to work well. Only the `make install` of gcc 4.3.6 fails. It dies with this error: cc1: error: unrecognized command line option "-Wno-overlength-strings" gmp,mpfr, and mpc all compiled without error, passed `make check`, and were installed via `make install.` There were no issues. GCC 4.3.6 compiles without error (make) and passes almost 96,000 tests before `make check` dies (after >2hrs using -j4). GCC 4.3.6 was configured with: ../gcc-4.3.6/configure --prefix=/foo/HPC_apps/AMD --with-gmp-lib=/foo/HPC_apps/AMD/lib --with-gmp-include=/foo/HPC_apps/AMD/include --with-mpfr-include=/foo/HPC_apps/AMD/include --with-mpfr-lib=/foo/HPC_apps/AMD/lib Please note that (per the instructions) I am NOT building in the source directory. I Googled until I reached the end of the Internet... and, well, after that I decided to write this e-mail. What gives? Is there an environment variable that can be set to force gcc to not attempt to use this option (in the configure logs, it discovers that "-Wno-overlength-strings" is not an available option. WTF?
