How to enable all compiler warnings in CLion?

Question

I want to see all compiler warnings in CLion. I don't want them treated as errors, but I want to inspect all of them.

How can I do this?

Try to set compiler flag in CMakeLists.txt:

set (CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -Wall -Wextra")

Answer 2

Rebuild your entire project. Most compilers don't rebuild every file when you just press build, so you will only see warnings from files that were changed.

Answer 3

For C:

set (CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -Wall -Wextra")
