CUDA 7.0 complains about not supporting gcc 4.9

I have installed gcc-4.7, gcc-4.8, gcc-4.9

When I try to do:

luarocks install cutorch

I get an error:

In file included from /usr/include/cuda_runtime.h:59:0,
                 from <command-line>:0:
/usr/include/host_config.h:82:2: error: #error -- unsupported GNU version! gcc 4.9 and up are not supported!
 #error -- unsupported GNU version! gcc 4.9 and up are not supported!

I found a similar problem

But when I try to run the command:

nvcc --compiler-bindir /usr/bin/gcc-4.7

I get an error:

nvcc fatal: No input files specified; use option --help for more information

I'm new and installed linux day ago. Please help me

Run the following commands before the installation:

export CXX=/usr/bin/g++-4.8
export CC=/usr/bin/gcc-4.8

this should set the compiler to gcc-4.8 for the compilation.
