Your last question really doesn't make sense. How do I express that the main executable will be compiled with g++ and one nested library with gcc? Don't use old style cmake unless you have to (that path is a land of nightmares)
#CMAKE DEBUG FLAG GENERATOR#
Those functions support generator expressions. Use add_compile_definitions, add_compile_options, etc. Using CMAKE_BUILD_TYPE will result in bad builds for any multi-configuration generator!įurther more sometimes you need to set things globally and not just for one target.
NOTE: How I'm using generator expressions to specify the configuration! Target_compile_definitions(foobar PRIVATE # target_compile_options, target_link_options, etc. You may also manually set the relevant flags at configure time and these will. # Add this compile definition for debug builds, this same logic works for Compilers: To prevent CMake from identifying mixed toolchains during.
#CMAKE DEBUG FLAG HOW TO#
How to configure for a debug build or a release build. The modern practice is to use target's and properties. How to see compile flags and definitions and how to control them. Build with a profile The enabled profiles are listed in the Run/Debug configuration switcher. Change the profile name, build type, and other settings as required. You will most likely have to engage in debugging your CMake scripts at one point or. Click, and CLion will add a new profile to the list. How to see compile flags and definitions and how to control them. How do I specify debug and release C/C++ flags using CMake? Add a new profile Go to Settings Build, Execution, Deployment CMake. If you'd like a deeper understanding I'd suggest reading a bit about cmake in Craig Scott's book "Professional CMake: A Practical Guide This is basically the result of handling build systems that support multiple-configurations in 1 build. It's a meta-build system (IE a build system that build's build systems). If you are wondering why this is necessary it's because cmake isn't a build system. B build/ -D CMAKE_BUILD_TYPE=Releaseįor multi-configuration generators it's slightly different (Ninja Multi-Config, Visual Studio) # Configure the build Entering Debug in the CMAKEBUILDTYPE field will allow you to build with debug flags. B build/ -D CMAKE_BUILD_TYPE=DebugĬmake -S. Solved-How do you set GDB debug flag with cmake-C++. If you are using a single configuration generator (Ninja/Unix-Makefiles) you must specify the CMAKE_BUILD_TYPE.Ĭmake -S. You can run CMake with CMAKEBUILDTYPEDebug. CMake does this for you with build types.
How do I run CMake for each target type (debug/release)?įirst off Debug/Release are called configurations in cmake (nitpick). To run a C++ debugger, you need to set several flags in your build. wont be viewable in the debugger 371, if( CMAKECXXCOMPILERID MATCHES Clang ) 372. Granted I'm answering this question in 2020, so it's expected things would change. Activity 369, 369 370, Clang needs this flag or wxStrings, etc. So I'm going to attempt to answer it better. A lot of the answers here are out of date/bad.
