Is it possible to install g ++ on CentOS without root?

I have an i7 core with CentOS 5.8 that I use SSH to use simulations. Unfortunately, it only has gcc version 4.1.2. This seems to produce significantly slower programs than what I get when compiling with optimizations on my slower laptop with Microsoft Visual Express C ++ 2010. I tried various g ++ optimization flags, but they don't help much, so I think what i need to update gcc.

I do not have a root on the machine, so it seems to me that I should install it in my home directory. Is this possible, and if so, are there any specific instructions necessary for this?

thanks

You can use EasyBuild, which allows you to very easily install a specific version of GCC without requiring root, see http://hpcugent.github.com/easybuild .

If you are building the original tarball, I believe you should go with ./configure --prefix=~/path/to/build/into , and then make and make install .

You can also use GNU SRC ..

After configuration, go to the gsrc directory and specify the following commands:

 make -C gnu/gcc make -C gnu/gcc install
