QtCreator CMake and compier defines

olejl77

In CmakeLists.txt i set the following define:

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -DTEST_DEFINE")

In my source code I have the following:

#ifdef TEST_DEFINE
  return 1;
#else
  return 2;
#endif

In Qt Creator, the coloring indicates that TEST_DEFINE is not defined, but when compiling it is defined. What is the proper way to make Qt Creator aware of the defines set in CMakeLists.txt

Hi,

After modifying your CMakeFile.txt did you re-run cmake ?

olejl77

@SGaist Yes

SGaist

Which version of Qt Creator are you using ?

Does it work correctly if you use add_definitions() instead?

@SGaist I'm using Qt Creator 4.0.3.

@mchinand Yes it is working when using add_definitions() instead. Thanks
