Yes, the symbolic links called "gmp", "mpfr" and "mpc" in the gcc-4.9.0 source directory are present. I foolowed instructions from the installation guide https://gcc.gnu.org/wiki/InstallingGCC directly, but nevertheless got the following error (in config.log) when doing make (after successful configure) configure:4970: checking whether g++ accepts -static-libstdc++ -static-libgcc configure:4987: g++ -o conftest -g -O2 -static-libstdc++ -static-libgcc conftest.cpp >&5 g++: unrecognized option '-static-libstdc++' conftest.cpp:11:2: error: #error -static-libstdc++ not implemented configure:4987: $? = 1 configure: failed program was: | /* confdefs.h */ | #define PACKAGE_NAME "" | #define PACKAGE_TARNAME "" | #define PACKAGE_VERSION "" | #define PACKAGE_STRING "" | #define PACKAGE_BUGREPORT "" | #define PACKAGE_URL "" | /* end confdefs.h. */ | | #if (__GNUC__ < 4) || (__GNUC__ == 4 && __GNUC_MINOR__ < 5) | #error -static-libstdc++ not implemented | #endif | int main() {} The configure coomand was like ./contrib/download_prerequisites $PWD/../gcc-4.9.0/configure --prefix=/ifs/home/icmmg/voronin/pardiso_proekt/pardiso_project/new/gcc-4.9.0 --enable-shared How should I solve the problem?
