Although I configured the gcc alternatives and set gcc-4.6 instead of gcc-4.8, cmake was only detecting the 4.6 version for C compiler while using 4.8 for C++. After explicitly setting C++ to 4.6 and running cmake and make again, the problem seems to have been resolved!

Although I bumped into a "Disk Full" issue earlier, this was not the cause this time since the disk already had 1.7 GB available. It seems however that this problem is caused by an incorrect C++ compiler version. Although I configured the gcc alternatives and set gcc-4.6 instead of gcc-4.8, cmake was only detecting the 4.6 version for C compiler while using 4.8 for C++.

I'm having a problem building OpenCV 2.4.8 with GPU support on an Ubuntu machine with CUDA 5.5.22 installed. I'm stuck with the following error. I'm not sure what exactly is going wrong. Any help is much appreciated.
