Another good reason is because ST provides cheap and efficient demo boards. I have been using MCUs from this family for years now, which is a good reason to use them here. STM32 is a family of 32-bit processors by ST-Microelectronics, based on ARM Cortex-M designs. CMake is by far the most widely used build system in the C++ world, and better integration with it is sorely needed. It is becoming so popular that it will probably be the build tool for Qt6:įor Qt 6, we aim to use CMake as a standard 3rd party build system to build Qt itself. In fact, it is more about CMake on MCUs but I had to pick one for the examples.ĬMake is becoming the de-facto standard tool to build C and C++ projects.

Plus the lists of files ( module.source, headers.source and module_test.source).This article is the first of a series dealing with CMake and STM32 microcontrollers. We can see the module name is aodv and it depends on the internet and the wifi libraries, extend () headers = bld ( features = 'ns3header' ) headers. source = # Tests encapsulating example programs should be listed here if ( bld. create_ns3_module_test_library ( 'aodv' ) aodv_test. NS3_WARNINGS_AS_ERRORS controls whether compiler warnings are treatedĪs errors and stop the build, or whether they are only warnings andĭef build ( bld ): module = bld. NS3_ASSERT and NS_LOG control whether the assert or logging macros In addition to setting compiler flags each build type also controls whether certain features are enabled or not: ns3 -build-profile
The mapping of the ns3 build profiles into the CMake build types is the following: Equivalent build profiles To familiarize Waf users with CMake and how the options names changed. The summary with enabled feature shows both the release build type, along withīelow is a list of enabled modules and modules that cannot be built.Īt the end, notice we print the same commands from -dry-run. Notice that CCache is automatically used (if installed) for your convenience. wifi wimax Modules that cannot be built: brite click openflow visualizer - Configuring done - Generating done - Build files have been written to: /ns-3-dev/cmake-cache Finished executing the following commands: mkdir cmake-cache cd cmake-cache /usr/bin/cmake -DCMAKE_BUILD_TYPE=release -DNS3_NATIVE_OPTIMIZATIONS=OFF -DNS3_EXAMPLES=ON -DNS3_TESTS=ON -G Unix Makefiles.
