OpenSUSE 11.0 and Ubuntu 8.04 with GCC version 4.3 or later are the Linux distributions supported for the current SDK.
One thing you can try doing though, is to recompile your libstdc++ and see.
Thanks for the reply omkaranathan. Yes I am aware of the supported distributions. The advice I mentioned (from ATI_Stream_SDK_Installation_Notes.pdf) regarding libstdc++.so.5 relates to its absence in the unsupported distro: RedHat Enterprise Linux 5.1.
There is no reason to recompile GCC 4.4's libstdc++ without further modifications as I will receive exactly the same libstdc++.so.6 Perhaps there's a GCC compile switch to enable GLIBC_2.4?
Can anyone else offer advice?
