CMAKE DEBUG RELEA GENERATOR

There are distinct flags for this mode (variables ending in _DEBUG as opposed to _RELEASE), as well as a generator expression value CONFIG:Debug or CONFIG:Release. In multi-configuration generators, like many IDEs, you can pick the configuration in the IDE.

CMAKE DEBUG RELEA CODE

Building in debug modeįor single-configuration generators, you can build your code with -DCMAKE_BUILD_TYPE=Debug to get debugging flags. If you add -trace-expand, the variables will be expanded into their values. There are related options as well, but they tend to bury you in output.įor example: cmake -S. Every line run in the file that you give will be echoed to the screen when it is run, letting you follow exactly what is happening. Have you wanted to watch exactly what happens in your CMake file, and when? The -trace-source='filename' feature is fantastic. If you want to print out a property, this is much, much nicer! Instead of getting the properties one by one of of each target (or other item with properties, such as SOURCES, DIRECTORIES, TESTS, or CACHE_ENTRIES - global properties seem to be missing for some reason), you can simply list them and get them printed directly: cmake_print_properties( However, a built in module makes this even easier: include(CMakePrintHelpers) The time honored method of print statements looks like this in CMake: message(STATUS 'MY_VARIABLE=$') CMake debuggingįirst, let's look at ways to debug a CMakeLists or other CMake file. Once you make a debug build, you can run a debugger, such as gdb or lldb on it.You might need to debug your CMake build, or debug your C++ code.

But many people (especially CMake old-timers like the. Bbuild -DSOMEDEFINITION 'something' cmake -build build.

In the previous episode we have learned how to configure and build: cmake -S.

How to configure for a debug build or a release build.

Every line run in the file that you give will be echoed to the screen when it is run, letting you follow exactly what is happening. How to see compile flags and definitions and how to control them. You might need to debug your CMake build, or debug your C++ code.
