Fakeroot fails with externalsrc

Fakeroot fails with externalsrc

Hi

I'm trying to make a CI/CD Yocto build in a git repository which is used in a recipe.

I have made an include file  meta-codesys/recipes-codesys/codesys-src.inc which normally contains.

The problem is that do_package tries to set uid to root, but that is not allowed, unless fakeroot is used.
Why does this fail when externalsrc is used?

Just for the record, if I do not change codesys-src.inc it builds.

Pseudo ignores the source- and build-dirs[1] (and everything that's
inside them), via the PSEUDO_IGNORE_PATHS variable.
E.g. When you set "/userdata/codesys-runtimes" as EXTERNALSRC, that
becomes ${S} - every path that starts with this prefix will be outside
of fakeroot.
You need to change this folder structure in a way that the EXTERNALSRC
path doesn't clash with your Yocto build-dir - build-dir can contain the
source-dir, but the source-dir shouldn't contain the build-dir.

Thanks, that makes sense.

I kept yocto under my project, because I wanted to take advantage of the Gitlab CI cache.
But I solved the problem instead by setting a TMPDIR.
