Partial compilation of the openwrt project

Question

I would like to get a view or a link to compile only a subset in an openwrt project. I know the menuconfig utility, but this is not enough for my purpose.

I would like to compile only a tool chain (binutils + gcc + glibc) for a specific purpose (ar71xx), as well as the kernel.

Now, having looked in the makefiles, etc., I noticed that most of the work is to actually fix the toolchain and the kernel, and then compile it. is it possible to stop the build process after the fix, so I can only have the corrected source code, and I can write my own make file to compile it?

Answer 1

To prepare the (patch) toolchain yourself:

make toolchain/{clean,prepare} V=99

Answer 2

:

make target/linux/{clean,prepare} V=99

build_dir/linux - $(target)/linux - $()
