Hi,

I am using PGI 12.10 on CentOS 5.8 .

There is two version of GCC 4.1.2 and 4.4.7 . The default is 4.1.2.

I am looking for compiling with g++44( secondary GCC 4.4.7) .

Are there any suggestions to switch the secondary GCC (excluding to upgrade OS, to uninstall GCC 4.1.2, or to reinstall PGI) ?

Thanks in advance.

Hi mhasumi,

The quick method is to edit your installation's "localrc" file to point to the new GCC installation. The caveat is that for compatibility reasons, we provide some system header files which can change depending upon the GCC version. Also, older PGI versions may not be compatable with newer GCC installations.

Hence, the preferred method is to re-install after you have switched to using GCC 4.4.7 by default. We don't have a method to switch between GCC installation on a single host.
