B build/release -DCMAKE_BUILD_TYPE=RELEASE \ DCMAKE_TOOLCHAIN_FILE=toolchain-STM32F407.cmakeĬmake -S. B build/debug -DCMAKE_BUILD_TYPE=DEBUG \ Unfortunately, this means we have to run two very similar cmake commands to generate different configurations: cmake -S. Our underlying build system for training is Make, so we need to create separate output folders for each type of build we require. 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 capitalised types. Suggested build types are values such as Debug and Release, but CMake allows any type that is supported by the build tool. Configuring Debug and Release BuildsĬMake refers to different build configurations as a Build Type. When using CMake to generate different build requirements using make files we take this into account by placing different build configurations in different output directories for each type of build we want to support.
On the other hand, the Unix/Linux/GNU Make system does not support build configurations. Therefore, we need to configure our build process to cater for these different output requirements.īoth Visual Studio and Xcode support multiple build configurations, and CMake can generate appropriate build configuration files for these systems. For example, a developer’s build typically includes metadata used by a debugger which is not required for a released version of the project. Outputs from each type of build configuration are usually different. We usually do this using build configurations. To support the different phases and objectives of a Software Development Lifecycle a project will need to differentiate between developing code, testing (in its various forms) and releasing a version for end-use.
In the real world, projects are never as simple as this minimal example, and we try to reflect this in our training.
B build -DCMAKE_TOOLCHAIN_FILE=toolchain-STM32F407.cmake The CMake commands used to generate and build the project are: cmake -S.
CMAKE DEBUG UNOPTIMIZED GENERATOR
We looked at the minimum requirements to configure the CMake build generator for a cross-compilation project using a project definition file ( CMakeLists.txt), a toolchain definition file ( toolchain-STM32F407.cmake).
CMAKE DEBUG UNOPTIMIZED HOW TO
In my previous blog post CMake Part – The Dark Arts I discussed how to configure CMake to cross-compile to target hardware such as our STM32F407 Discovery board.
