The CUDA 9.2 release adds support for gcc 7.As of the CUDA 9 release, gcc 6 is fully supported on Ubuntu 16.04, Ubuntu 17.04 and Fedora 25.As of the CUDA 8 release, gcc 5.3 is fully supported on Ubuntu 16.06 and Fedora 23.As of the CUDA 7.5 release, gcc 4.8 is fully supported, with 4.9 support on Ubuntu 14.04 and Fedora 21.As of the CUDA 7.0 release, gcc 4.8 is fully supported, with 4.9 support on Ubuntu 14.04 and Fedora 21.As of the CUDA 6.0 release, gcc 4.7 is now supported.As of the CUDA 5.0 release, gcc 4.6 is now supported.As of the CUDA 4.1 release, gcc 4.5 is now supported.Since it was written, NVIDIA has continued to expand support for later gcc versions in newer CUDA toolchain release Note that this question, and answer, pertain to CUDA 4. Pass that local directory to nvcc via the -compiler-bindir option, and you should be able to compile CUDA code without affecting the rest of your system. Create a local directory and then make symbolic links to the supported gcc version executables. There is an option to nvcc -compiler-bindir which can be used to point to an alternative compiler. Your only solution is to install a gcc 4.4 version as a second compiler (most distributions will allow that). You cannot use them, and the restriction is non-negotiable. Gcc 4.5 and 4.6 are not supported with CUDA - code won't compile and the rest of the toolchain, including cuda-gdb, won't work properly. Downgrading is not an option as gcc4.6 has a whole system as a dependency at this point.

Then finally the SDK (both the 4.0.17 version). I have installed the developers driver (version 270.41.19) and the CUDA toolkit, I have troubles compiling some of the examples shipped with CUDA SDK.
