At work we developed a project under Linux with the cmake build tool and gcc. This project does not use Qt, but I wanted to use Qtcreator as IDE when trying to port the project to Windows.

When trying to compile after solving the dependencis issues, I got

I searched a lot a lot a lot with no luck. Finall, I found that we forced to use the "-W" switch under Linux to force gcc warning. It was considered also as a switch under Windows by error (while it was -W and not /W).

The bad content of the CMakeLists.txt was:

Qt Code: 
  1. set(CMAKE_CXX_FLAGS "-W -Wall")

Hope this can help future people having to port cmake based projects to windows...
