Officially CodeXL is supported on RedHL/CenOS and Ubuntu so those come with the proper libstdc. The libstdc is usually installed with gcc-44 or later and this is usually installed on those machines.
You can install gcc-44 with zypper command on openSUSE.
Hope this helps
OpenSUSE 12.3 comes with gcc-47, shouldn't that include libstdc as well?
When I try to install CodeXL 1.2 I get the following warning:
Problem: nothing provides libstdc++ >= 4.0 needed by AMD_CodeXL_Linux-1.2.2484-0.x86_64
