Open a terminal in the build output folder: Build files have been written to: /home/jshankar/codeprojects/tm4c123gxl/blinky/build Build it with make CMAKE_TOOLCHAIN_FILE is: /home/jshankar/codeprojects/tm4c123gxl/blinky/arm-toolchain.cmake Not searching for unused variables given on the command line. Executing command: /usr/bin/cmake –no-warn-unused-cli -DCMAKE_EXPORT_COMPILE_COMMANDS:BOOL=TRUE -DCMAKE_BUILD_TYPE:STRING=Debug -DCMAKE_C_COMPILER:FILEPATH=/opt/toolchains/gcc-arm-none-eabi-10.3-2021.10/bin/arm-none-eabi-gcc -DCMAKE_CXX_COMPILER:FILEPATH=/opt/toolchains/gcc-arm-none-eabi-10.3-2021.10/bin/arm-none-eabi-g++ -S/home/jshankar/codeprojects/tm4c123gxl/blinky -B/home/jshankar/codeprojects/tm4c123gxl/blinky/build -G “Unix Makefiles” Compiler paths will be determined by reading CMakeCache.txt.
This version of CMake does not support the “toolchains” object kind. Executing command: /opt/toolchains/gcc-arm-none-eabi-10.3-2021.10/bin/arm-none-eabi-gcc -v Successfully loaded 3 kits from /home/jshankar/.local/share/CMakeTools/cmake-tools-kits.json
Select CMake:Delete cache and Reconfigure.With CMake it is a two stage process: running CMake to create (or configure) the make files and then we use ‘ make’ to build it. Actually we need to ‘ configure’ it first. set(BINUTILS_PATH $ PRIVATE ): list of linker options.set(ARM_TOOLCHAIN_DIR “C:/ProgramData/chocolatey/bin”).DCMAKE_TOOLCHAIN_FILE= CMake: Toolchain File This can be done both in the command line or in CMakeLists.txt before project() command:Ĭmake. All we need to do is to put toolchain variables into a separate file (e.g.cmake) and set CMAKE_TOOLCHAIN_FILE variable to the path of that file. Second option is more elegant and is the preferred way of choosing the toolchain. DCMAKE_C_COMPILER= -DCMAKE_CXX_COMPILER= -DCMAKE_AR= -DCMAKE_LINKER= etc… pass values for the toolchain variables from the command line,įirst option is very explicit thus easy to understand, but big number of arguments makes it harder to use CMake in terminal:Ĭmake.This can be accomplished in one of two ways: When we cross-compile to another platform, we must use a whole different toolchain in terms of the binaries’ names and locations. They both contain paths to the C and C++ compilers. CMake keeps information about the current toolchain in the following variables after successful detection: CMake will utilize these new settings as default compilers if we manually adjust CC or CXX to other values. They specify which compiler is the system’s default. The CC and CXX environment variables are checked. CMake needs to know where to look for the tools. To create the project, we’ll use CMake in conjunction with Make.
#CMAKE SET PRIVATE VARIABLE CODE#
Visual Studio Code and CMake are combined in the CMake Tools extension to make it simple to configure, build, and debug your C++ project. CMake is an open-source, cross-platform tool that generates native build tool files unique to your compiler and platform using compiler and platform agnostic configuration files.
