How can I compile with gcc3.3.3?

[raw19896]

Hey everyone,

This is my first post here and I am very new to the Linux field. I've been tinkering for a while and am adept at most basic task so bear with me while I figure things out.

I am currently trying to compile a version of OpenMPI 1.2.5. To make it compatible with an application I am using, it needs to be compiled with GCC 3.3.3. My system (RHEL) reports that a compatibility library is currently installed, compat-libstdc++-33, and I was under the impression that was for gcc 3.3.x . The problem is, I have no idea how to invoke this version. And for reference, OpenMPI is built through simple ./configure and make all install commands.

If that's not the right approach to fix that, what do you think I should do? I need to keep the current version of GCC installed. I'm open to any approach; any help is appreciated. Thanks!

If you run ./configure --help it will give you the options needed to use another compiler. In your case, you need to use gcc33 for the CC parameter.

Dear friend,
If you compile by just ./configure means , it will replace old gcc, do you have to install it in seperate directory using this command

./configure --prefix=/usr/gcc --libexecdir=/usr/gcc/lib --enable-shared --enable-threads=posix --enable-_cxa_atexit --enable-clocale=gnu --enable-languages=c,c++ --disable-multilib --with-mpfr=/usr/gcc


You need to have the dependency packages of mpfr,gloob
