Clion is a great IDE and I really enjoy it. But, with some little buts:
The indexer is CMake oriented. It learns what to index and how by cmake directions.
In many cases we work with a makefile projects. Usually it's pretty easy to convert it to cmake for the CLion indexer to work properly.
But, when it comes to preprocessor includes what would you do ?
By preprocessor includes I mean "-include" compiler directions passed to gcc.
My hacky-but-working solution was to add the includes directions to each file, wrapped in #ifdef block that will be false on compilation but true for CLion indexer:
#ifdef CLION_PREPROCESSOR_INCLUDE #include <...> #endif
In CMakeLists.txt add_defenitions will contain -DCLION_PREPROCESSOR_INCLUDE
And now the indexer will work fine :D
Another issue was discovered during this hack.
Clion indexer has the classic bug of recursive indexing a file contains #include directive to itself ...
