path/to/project/src/file1.cpp:1:10: fatal error: 'file1. The cmake-properties(7) manual entries for are printed in a human-readable text format. The help is printed to a named ile if given.-help-property Print help for one property and exit.When I create a Makefile and run make on it, the compiler barfs immediately, with the error message: The cmake-policies(7) manual is printed in a human-readable text format. Unknown CMake command "get_directory_properties". I tried that and of course CMake immediately failed to generate the Makefile and complained: I searched online, and so a post that recommended using get_directory_properties. I can't however, for the life of me, work out what on earth is being passed to the compiler as the include directories. I have verified that this variable contains the correct files. I am trying to build it using the following commandĬOMMAND $ is a list variable that contains all the C++ files I need to compile. My CMakeLists.txt file contains the following section, which I, having read the CMake documentation, rather naively believed, will be specifying the include directories for the project: INCLUDE_DIRECTORIES (include/ I have a directory structure that looks something like this: project: Choose from our vast catalog of 342 premium products. Design authentic apparel and unique home & living decor. I am trying to build a trivial proof of concept project using CMake, and I am rapidly getting tired of it - to the point that I think it may have been a better idea to handcraft my own damn Makefile. If they can trust and rely on our products and services, so can you. Craig Scott has written an article on the subject here. The list of targets can be used for something else. My use case was to generate an installation option for each target automatically. After using addexecutable () or addlibrary (), use that macro to insert the target in the list. Inside a cmake module, define a property to contain the list of targets. If you want to do performance profiling of CMake script execution, see the -profiling-output and -profiling-output flags.īonus info: If you want to profile build performance, you can look into the facilities provided by the tools in your toolchain, such as Ninja and Clang. It is more intrusive, but somewhat simple. To debug try_compile/ try_run failures, use the -debug-trycompile flag To debug commands that find things like find_program(), find_library(), find_file(), find_path(), and find_package(), use the -debug-find flag, or for debugging at more granular scopes, the CMAKE_FIND_DEBUG_MODE variable. To make CMake warn when uninitialized variables are used, use the -warn-uninitialized flag. To watch variables for changes, use the variable_watch command. To put CMake in a debugging mode where it prints things like stack traces with message(SEND_ERROR) calls, use the -debug-output flag To make CMake emit warnings about deprecated functionality, use the -Wdeprecated flag To make CMake emit developer warnings meant for CMakeLists.txt authors, use the -Wdev flag To put CMake in a trace mode where it prints all calls made and from where, use the -trace flag and/or related flags like -trace-expand, -trace-format, -trace-source and -trace-redirect. Other CMake debug-related facilities you may find useful include to following: Information previously logged to those files is instead logged to the cmake-configure-log(7). cmake(1) no longer suggests looking at them after a CMake Error occurs. The CMakeFiles/CMakeOutput.log and CMakeFiles/CMakeError.log files are no longer populated by CMake's built-in modules. Starting with CMake v3.26, the CMakeFiles/CMakeOutput.log and CMakeFiles/CMakeError.log files will no longer be supported / created. Pre-CMake v3.26, you can (as suggested by CMake's diagnostic messages) look at the CMakeFiles/CMakeOutput.log and CMakeFiles/CMakeError.log files in the generated buildsystem's binary/build directory. See also the -cmake-debugger-pipe flag and the -debugger-dap-log flag. Related to that, CMake 3.27 exposes the -debugger flag to enable interactive debugging using the Debug Adapter Protocol. Qt Creator will likely have a CMake debugger in the future Visual Studio announced their CMake debugger on February 22nd, 2023 In context: mkdir -p release cd release cmake -DCMAKEBUILDTYPERelease -DCMAKEEXPORTCOMPILECOMMANDSON -G Ninja. Can somebody please enlighten me as to what the command line flag to CMake might be that will make it print out all the compile/link commands. CLion announced their CMake debugger on October 25, 2022 You can also get cmake to produce a json file of all commands to be run with: -DCMAKEEXPORTCOMPILECOMMANDSON.
