Compilation of symengine (https://github.com/symengine/symengine) in local folder on LXPLUS fails with errors…

CMake Error at CMakeLists.txt:48 (message): Compiler does not support C++11 constructs.
cc1plus: error: unrecognized command line option “-std=c++11”

I’m using gcc 4.4.7 located in /usr/bin.

Use of “-Dcxx11=ON” as explained in C++11 support does not help.

Sorry, but how is this related to ROOT?

You need gcc 4.8.x or newer.
