Is CUDA 5.5 supposed to refuse to install when using GCC 4.7.3 (linux 64bit)?
The installer reports the following:
Unsupported compiler: 4.7.3
Driver: Not Selected
When i extract the individual installers with ./cuda_5.5.22_linux_64.run --extract=~/cuda/
Looking at the installed /opt/cuda/include/host_config.h i think it should support GCC 4.7.3:
#if defined(GNUC )
#if GNUC > 4 || (GNUC == 4 && GNUC_MINOR > 8)
#error – unsupported GNU version! gcc 4.9 and up are not supported!
#endif /* GNUC > 4 || (GNUC == 4 && GNUC_MINOR > 8) */
#endif /* GNUC */
So is this an error in the linux installer?
You are correct that 4.7.3 is a supported version of gcc, so this looks like a bug in the installer.
Could you please post the output of gcc -v. This will help me determine what’s going on in your use case.
In the meantime, you can workaround this issue by running the installer with the --override flag:./cuda_5.5.22_linux_64.run --override
This will ignore all checks within the installer, specifically the gcc version check.
Edit: Fixing command line to run

Thank you for your reply Andy.
Here is the output of gcc -v:
