An example of data being processed may be a unique identifier stored in a cookie. This can be achieved by not specifying features with Suggested build types are values such as Debug and Release, but CMake allows any type that is supported by the build tool.The build type specification is case insensitive, so we prefer to be consistent and use all upper case types despite the fact that the CMake documentation refers to . For other compilers that should be similar except the switch to include debug info symbols that can be different. Use the LINK_OPTIONS target property or target_link_options () command to add link flags explicitly. This is what we'll use for add-symbol-file. Or, press the Run button in the toolbar. generator expression to implement Compile feature requirements may be specified with the (If It Is At All Possible).

In this case, the above suggestions to do something like set(CMAKE_CXX_FLAGS_DEBUG "${CMAKE_C_FLAGS_DEBUG} -O0") resulted in "-O2 -g -O0" which doesn't disable optimization. I'm trying to figure out how to build Release config . For single-configuration generators, you can build your code with -DCMAKE_BUILD_TYPE=Debug to get debugging flags. And if you need optimisation with debug symbols, see catkin_make's option for optimization: For a release configuration with opmizations and no debugging symbols, you can use the Release build type: catkin_make -DCMAKE_BUILD_TYPE=Release [Linux], Microsoft Azure joins Collectives on Stack Overflow. gdb.

To build MariaDB with symbols, to get better stack traces and to be able to debug the binary with gdb, you need to supply the -g3 option to the gcc compiler. Setting configuration type via CMAKE_BUILD_TYPE switches set of additional options for compiler to one, which normally reflects meaning of the configuration. In the side pane, choose Linker > Debugging, then select options for Generate . as the Clang feature test macros. #ifndef NDEBUG int a=1; std::cout<<a; #endif Option 2: target_compile_definitions The configuration is spelled Debug, not DEBUG.Since you should never, ever use directory-level commands (like add_compile_options), I'll show you how to use the target-level command instead: In processing the requirement for the cxx_constexpr feature, cmake (1) will ensure that the in-use C++ compiler is capable of the feature, and will add any necessary flags such as -std=gnu++11 to the compile lines of C++ files in the mylib target. I would say that changing CMAKE_BUILD_TYPE any way except for by passing directly to cmake should be avoided. We give our configuration a debug build type by default. for each target.

If the compiler is unknown then CMake won't know the right flags to pass to generate debug info. to detect the features actually available. My regex could probably use some fine tuning, but so far it seems to work well enough: Thanks for contributing an answer to Unix & Linux Stack Exchange! See this note from man obj-copy: only-keep-debug Strip a file, removing contents of any sections that would not be tripped by strip-debug and leaving the debugging sections intact.
