compilation using -std=c++11 and gcc 4.6 / 4.7 #1

Closed dcanelhas closed 11 years ago

I had to use update-alternatives --config gcc to select version 4.6 due to CUDA not supporting 4.7 yet.

During compilation I got an error regarding the use of the -std=c++11 flag on the examples.

A workaround for my system (3.8.0-29-generic #42-Ubuntu x86_64) was to change Kangaroo / applications / examples / CMakeLists.txt / line 5. from set(CMAKE_CXX_FLAGS "-std=c++11 -g")
to set(CMAKE_CXX_FLAGS "-std=c++0x -g")

I think you can also use CUDA 5.0, build example with gcc 4.6+ version and cuda with gcc 4.7- version.

Best, Lu

Updated compiler flags to be compatible with GCC 4.6.
