Yocto Tutorial - 09 Yocto Build Tasks (Part-6) | do_compile (With Example!!)
In this video, we'll be exploring the Yocto Compile Task, what it is, how it works, and how to use it.
The compile task is an optional step that compiles the source code if any compilation steps are available and generates a binary file.
In this tutorial, we'll be showing you how to define the compilation steps in the "do_compile()" function of bitbake. These steps define the compilation process for the source code, including the use of CC, CFLAGS, and LDFLAGS.
CC is the cross-compiler, CFLAGS are the flags passed to the compiler, and LDFLAGS are the flags passed to the linker.
By default, the compile task runs in the current source directory ${S}. Normally, the build process automatically executes the compile task. However, in this tutorial, we'll be executing the compile task explicitly so that we can analyze how it works.
To execute the compile task, we'll be using the command "bitbake -c do_compile recipe-name". This will execute the compilation steps and generate a binary file.
