The devtool add command automatically creates a recipe based on the source tree with which you provide it. Currently, the command has support for the following:
- Autotools (autoconf and automake)
- CMake
- Scons
- qmake
- Plain Makefile
- Out-of-tree kernel module
- Binary package (i.e. “-b” option)
- Node.js module
- Python modules that use setuptools or distutils
Apart from binary packages, the determination of how a source tree should be treated is automatic based on the files present within that source tree. For example, if a CMakeLists.txt file is found, then the source tree is assumed to be using CMake and is treated accordingly.
Note : In most cases, you need to edit the automatically generated recipe in order to make it build properly. Typically, you would go through several edit and build cycles until you can build the recipe. Once the recipe can be built, you could use possible further iterations to test the recipe on the target device.
Now, lets try to create recipe for strace using devtool add command automatically as,
