Hello, I have the following system [~]$ uname -a Linux centos2.aurora.local 2.6.18-164.15.1.el5 #1 SMP Wed Mar 17 11:30:06 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux and need to install a newer gcc with yum I only get [~]$ gcc --version gcc (GCC) 4.1.2 20080704 (Red Hat 4.1.2-46) Copyright (C) 2006 Free Software Foundation, Inc.

I downloaded the sources for gcc 4.4.3 and did a ./configure && make bootstrap but this doesn't go through, the end of the output is checking whether ln -s works... yes checking for x86_64-unknown-linux-gnu-gcc... /home/Aurora/gcc/gcc-4.4.3/host-x86_64-unknown-linux-gnu/gcc/xgcc -B/home/Aurora/gcc/gcc-4.4.3/host-x86_64-unknown-linux-gnu/gcc/ -B/usr/local/x86_64-unknown-linux-gnu/bin/ -B/usr/local/x86_64-unknown-linux-gnu/lib/ -isystem /usr/local/x86_64-unknown-linux-gnu/include -isystem /usr/local/x86_64-unknown-linux-gnu/sys-include checking for suffix of object files... configure: error: in `/home/Aurora/gcc/gcc-4.4.3/x86_64-unknown-linux-gnu/libgcc': configure: error: cannot compute suffix of object files: cannot compile See `config.log' for more details. make[2]: *** [configure-stage1-target-libgcc] Error 1 make[2]: Leaving directory `/home/Aurora/gcc/gcc-4.4.3' make[1]: *** [stage1-bubble] Error 2 make[1]: Leaving directory `/home/Aurora/gcc/gcc-4.4.3' make: *** [bootstrap] Error 2 So I was wondering whether anybody has a pointer to how to build gcc 4.4.3 on such a system. Thanks.
