Topic: Updating gcc on Ubuntu 12.04 LTS

I need to update my gcc so I can compile the new functions in trunk. I have run this:

sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get update
sudo apt-get install g++-4.7 c++-4.7

Still no joy. I suspect that somehow the old gcc is still being used. Any ideas?

I modified compile.sh and added the compiler like this:

cmake -DWL_PORTABLE=true .. -DCMAKE_BUILD_TYPE="${var_build_type}" .. -DCMAKE_CXX_COMPILER=/usr/bin/g++-4.7

resulting in the following error:

-- The C compiler identification is unknown
CMake Error: your C compiler: "CMAKE_C_COMPILER-NOTFOUND" was not found.   Please set CMAKE_C_COMPILER to a valid compiler path or name.

Maybe I have to hack CMakeLists.txt somehow? I don't understand a word in that file though.

I checked /usr/bin/g++-4.7 and the file is there, the Synaptic package manager also lists g++-4.7 as installed.

Tino's edit should do the trick.

However I am not sure on why this happens. I had to do the same for the Ubuntu Precise PPA, and I only added the CMAKE_CXX_COMPILER parameter... maybe you need to remove everything in the build directory because CMAKE_C_COMPILER was available before.

CMake is evil.
