- CLion supports only GNU toolchain, that means only GCC and Clang compilers on Linux and OS X, and MinGW (or MinGW-W64) and Cygwin x64 toolchains on Windows.
Note: If you are using Visual Studio for C++ development (and Visual C++ Compiler), try our ReSharper for C++.
- CLion supports only the following C and C++ standards: C99, C++03, C++11.
- CMake 3 is not yet supported, still you can configure it in Toolchains settings and try to use at your own risk.
Performance and memory
- On the large code bases (especially when using Boost) performance and memory issues during indexing and editing are possible (increasing memory may help).
