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
very least Qt 5.4. It is also possible to compile against Qt 6. The

o --enable-cxx-mode=VALUE can be used to select a C++ standard, for
- example --enable-cxx-mode=11. The default is to try C++14, and then
- C++11.

o --enable-optimization=VALUE enables you to set optimization to a
higher level than the default, for example --enable-optimization=-O3.
+ Default is -Og when debugging is enabled, -O2 otherwise.
o --disable-optimization - you can use this to disable compiler
optimization of LyX. The compile may be much quicker with some
- compilers, but LyX will run more slowly.
