I know, it's an irony to compile a compiler. But I need a specific version of this compiler, and the CentOS 5.x repositories have not the most recent versions of GCC.

The version what i need is 4.3.2 but I only have 4.1.1.

I followed this tutorial to install the gcc http://www.mjmwired.net/resources/mjm-fedora-gcc.html and I used the following parameters at configure (before compiling):

/root/gcc/gcc-4.3.6/configure --prefix=/opt/gcc43 --program-suffix=43 --enable-languages=c,c++ --enable-shared --enable-threads=posix --disable-checking --with-system-zlib --enable-__cxa_atexit --disable-libunwind-exceptions --disable-multilib

The last option --disable-multilib save me for a another error that I got in previous compile tries (after a long compiling time...)

Also i set an enviroment variable, because in previous tries, i got errors, so i set as following:

export LD_LIBRARY_PATH=/usr/local/lib:/usr/local/lib:$LD_LIBRARY_PATH

That ensure the compiler to search mpfr and gmp libraries (which are needed) in that directory

So, i execute the 'make' command.

I though it was everything ok, because this time took more time (in my last try before setting that variable took me around 2 hours compiling)

I used a Micro instance in Amazon Web Services, this instance only have 1 single core x86_64 processor and 613 MB of RAM, so it took about 9 HOURS to compile.

Unfortunetly, i got errors again!!, now I got this:

make[2]: Entering directory `/root/gcc/build'
make[3]: Entering directory `/root/gcc/build'
rm -f stage_current
make[3]: Leaving directory `/root/gcc/build'
Comparing stages 2 and 3

make[2]: Leaving directory `/root/gcc/build'
make[1]: *** [stage3-bubble] Error 2
make[1]: Leaving directory `/root/gcc/build'
make: *** [all] Error 2

Any suggestions?

You likely didn't clean up properly in-between tries. Do a make distclean and try again. Sorry.
