I'm trying to figure out how to convince Yocto to build gcc using my local GIT source rather than standard location it uses.
By default the recipe to build GCC located in meta/recipes-devtools/gcc/gcc_5.2.bb. It includes gcc-5.2.inc, which points to
BASEURI = "${GNU_MIRROR}/gcc/gcc-${PV}/gcc-${PV}.tar.bz2"
as the location of the code.
Based on BitBake's documentation, I've created my own layer and gcc_5.2.bbappend append file. bitbake-layers show-appends shows that the system properly recognized the append file.
However, what this gcc_5.2.bbappend append file need to do to replace the source path? I've tried changing SRC_URI directly, prepending it with my own path. But it always stays the same and attempts to access the specified above path.
My original assumption that the /gcc/gcc_5.2.bb have to appended was incorrect. I've corrupted the specified above BASEURI to consistently cause an error. Running bitbake with -D option showed that there is a different recipe called gcc-source_5.2.bb that actually controls the source file acquisition and it had to be appended.
