Working with GNU make

GNU make is a make implementation for Linux systems. It is used by a wide variety of open source projects, including the Linux kernel. The build is managed by a Makefile, which tells make how to build the source code.

How to do it...

Yocto recipes inherit base.bbclass and hence their default behavior is to look for a Makefile, makefile, or GNUmakefile and use GNU make to build the package. If your package already contains a Makefile, then all you need to worry about are the arguments that need to be passed to make. make arguments can be passed using the EXTRA_OEMAKE variable, and a do_install override that calls the oe_runmake install needs to be provided, otherwise an empty install is run. For example, the mingetty recipe is based on a Makefile and looks as follows:

SUMMARY = "Compact getty terminal handler for virtual consoles only"             
SECTION = "console/utils"
