I've asked you repeatedly if you've followed the instructions at http://gcc.gnu.org/wiki/InstallingGCC and you claim to have done so, but your mail shows no evidence of it. Have you used the download_prerequisites script to build the support libraries in-tree? > Earlier I tried with download_prerequisites script but no use, because the > dependencies of gcc, > gmp, mpc and mpfr will get download and create a link that's it. script > will not build/compile gmp, mpc or >mpfr. we need to compile manually at > that only I got the error libgmp.so wrong file format Have you installed the support libraries from RPM? > No I have not tried with RPM files. But I would like to build the > gcc/gmp/mpc/mpfr packages by doing manual compilation(from source). > avoiding the use of RPM. If you install the 32-bit and 64-bit libraries via RPM then it should solve your issue, please try that instead of repeating the same question. > Please provide me solution other that RPM.. to solve the above issue.. > Many many thanks for reply.. -- View this message in context: http://old.nabble.com/gcc-4.6.2-build-issue..-tp33970982p33975698.html Sent from the gcc - Help mailing list archive at Nabble.com.
