![]() ![]() Where defining NDEBUG is added on platforms that support this (it disables assert()). In terms of compiler flags that usually means (since these are supported in most cases on all platforms anyway): 1. MinSizeRel: same as Release but optimizing for size rather than speed. RelWithDebInfo: optimized, *with* debug info, but no debug (output) code or asserts.Ĥ. Debug: No optimization, asserts enabled, ,ĭebug info included in executable (so you can step through the code with aĭebugger and have address to source-file:line-number translation).ģ. Release: high optimization level, no debug info, code or asserts.Ģ. The default build types that come with cmake more or less mean the following, 1. So, extended support for a build type needs updating every existing tool chain that you want to support. Most such compiler options are compiler and/or platform specific. Including 'debug info' in the executable ]. ![]() It is not used for multi-target generators as those simply generate a build system capable of building all build types (debug, release, etc). IMPORTANT: CMAKE_BUILD_TYPE only makes sense for single-target generators, like Makefiles. If I want to generate a production build, should I choose Release? Be aware that Release and RelWithDebInfo use different optimization levels on most platforms. If you are using an IDE such as Visual Studio, you should use the IDE settings to set the build type. I'm aware the differences between Debug builds and Release builds, but what are the differences between Release, RelWithDebInfo and MinSizeRel? I'm guessing RelWithDebInfo meant creating debuggable binaries, and MinSizeRel meant creating smallest possible size binaries. For example, in a build tree configured to build type Debug, CMake will see to having CMAKE_C_FLAGS_DEBUG settings get added to the CMAKE_C_FLAGS settings. There are many per-config properties and variables (usually following clean SOME_VAR_ order conventions), such as CMAKE_C_FLAGS_, specified as uppercase: CMAKE_C_FLAGS_. those which choose a single configuration when CMake runs to generate a build tree as opposed to multi-configuration generators which offer selection of the build configuration within the generated build environment. This variable is only meaningful to single-configuration generators (such as Makefile Generators and Ninja) i.e. Possible values are empty, Debug, Release, RelWithDebInfo and MinSizeRel. This statically specifies what build type (configuration) will be built in this build tree. If you run into issues or have suggestions for the team, please report them in the issues section of the extension’s GitHub repository.Specifies the build type on single-configuration generators. Feedback is welcomeĭownload the CMake Tools extension for Visual Studio Code today and give it a try. We recommend using the CMake Tools extension alongside the C/C++ extension for Visual Studio Code for IntelliSense configuration and a full-fidelity C/C++ development experience. The following screenshot of the extension shows a logical view of the open-source CMake project bullet3 organized by target (left) and several CMake-specific commands. You can visit the CMake Tools documentation and the extension’s GitHub repository to get started and learn more. The CMake Tools extension provides developers with a convenient and powerful workflow for configuring, building, browsing, and debugging CMake-based projects in Visual Studio Code. Thank you vector-of-bool for all of your hard work getting this extension to where it is today! About the extension The extension was created and previously maintained by vector-of-bool, who has moved on to other things. Microsoft is now the primary maintainer of the CMake Tools extension for Visual Studio Code. ![]()
