[yocto] Building local sources

[Erik Botö]

Hi,

I think you should set S to whatever directory that contains your
source, it has a default to ${WORKDIR}/${PN}-${PV} if I remember
correctly.

So S = "${WORKDIR}/${PN}"  should work if the recipe is named the same
as the subdir in git, otherwise just set it explicitly using e.g.  S =
"${WORKDIR}/module_a"

Side note: Your example uses an underscore, which means that a and b
would be interpreted as versions, which is probably not intended. See
http://www.yoctoproject.org/docs/1.6/dev-manual/dev-manual.html#new-recipe-storing-and-naming-the-recipe

Cheers,
Erik

So I used EXTRA_OEMAKE to get them to use the proper target toolchain.  Problem lies with the SRC_URI, my files from module_a gets copied into $WORKDIR and not into $S, as such the compile step failed.  I understand that SRC_URI is not really the proper usage in such situation, appears to be meant to retrieve external packages and some files here and there, mostly patches.  Even thought all my modules are within a git repo, I do not want to extract the full repo for each modules either.
