How To setup GCC 4.4 for CUDA

If the version of GCC on your computer is 4.5, NVCC is not going to work and complain. To fix this, follow these steps:

• Install GCC 4.4 (On ubuntu use: $ apt-get install gcc-4.4)
• Go to the folder that you installed CUDA (/usr/local/cuda)
• Go to the bin folder
• Make symbolic links for gcc, cpp and g++

ln -s /usr/bin/gcc-4.4 gcc
ln -s /usr/bin/cpp-4.4 cpp
ln -s /usr/bin/g++-4.4 g++
