First of all, you will need a C++11 standard conforming compiler, like g++ (at
least 4.9, to have proper srd::regex) or clang++.
-LyX makes great use of the C++ Standard Template Library (STL).
-This means that gcc users will have to install the relevant libstdc++
-library to be able to compile this version of LyX.

For full LyX usability we suggest to use Qt 5.6 and higher, or at the

only special point to make is that you must ensure that both LyX and
the Qt libraries are compiled with the same C++ compiler.
