| Host tools |
| ========== |
| |
| Building tools for Linux |
| ------------------------ |
| |
| To allow distributions to distribute all possible tools in a generic way, |
| avoiding the need of specific building tools for each machine, a tools-only |
| defconfig file is provided. |
| |
| Using this, we can build the tools by doing:: |
| |
| $ make tools-only_defconfig |
| $ make tools-only |
| |
| Building tools for Windows |
| -------------------------- |
| If you wish to generate Windows versions of the utilities in the tools directory |
| you can use MSYS2, a software distro and building platform for Windows. |
| |
| Download the MSYS2 installer from https://www.msys2.org. Make sure you have |
| installed all required packages below in order to build these host tools:: |
| |
| * gcc (9.1.0) |
| * make (4.2.1) |
| * bison (3.4.2) |
| * diffutils (3.7) |
| * openssl-devel (1.1.1.d) |
| |
| Note that the version numbers in parentheses above are the package versions at |
| the time of writing this document. |
| |
| There are 3 MSYS subsystems installed: MSYS2, MinGW32 and MinGW64. Each |
| subsystem provides an environment to build Windows applications. The MSYS2 |
| environment is for building POSIX compliant software on Windows using an |
| emulation layer. The MinGW32/64 subsystems are for building native Windows |
| applications using a linux toolchain (gcc, bash, etc), targeting respectively |
| 32 and 64 bit Windows. |
| |
| Launch the MSYS2 shell of the MSYS2 environment, and do the following:: |
| |
| $ make tools-only_defconfig |
| $ make tools-only |
| |
| |
| Building without Python |
| ----------------------- |
| |
| The tools-only builds pylibfdt by default. To disable this, use the |
| NO_PYTHON variable:: |
| |
| NO_PYTHON=1 make tools-only_defconfig tools-only |
