Wrong GCC version, but I have the correct GCC version...

[darkseid4nk 0]

How do I get the make files to use the correct version. According to my OS 6.3.0 is what I have configured, as you can see with gcc and g++ version output.

 

[email protected]:~/wow/TrinityCore/build# sudo update-alternatives --config gcc
There are 2 choices for the alternative gcc (providing /usr/bin/gcc).

  Selection    Path              Priority   Status
------------------------------------------------------------
* 0            /usr/bin/gcc-6     60        auto mode
  1            /usr/bin/gcc-4.8   60        manual mode
  2            /usr/bin/gcc-6     60        manual mode

Press enter to keep the current choice[*], or type selection number: 2

i suggest you to use clang like wiki states.

You should also run sudo update-alternatives --config g++

And check if you dont have CC/CXX environment variables defined pointing to 4.8
