I have a kernel module "rx" that I build on 2017.3, and the build breaks when I try to move my source into any subdirectory other than "files".
At first, I had the source code down in a "files" subdirectory (below my .bb file), and my FILESEXTRAPATHS_prepend variable was:
FILESEXTRAPATHS_prepend := "$(THISDIR)/files:"
My SRC_URI variable referenced all of the files, and everything worked.
However, I rearranged my code and git repositories, so that my code was then in subdir1/src/. I changed my .bb file to reference the new location with:
FILESEXTRAPATHS_prepend := "$(THISDIR)/subdir1/src:"
FYI: My SRC_URI refers to the files without prefix, such as:
SRC_URI = "file://Makefile \
file://COPYING \
...
Now, when I build with petalinux, I get strange errors:
Loaded 3273 entries from dependency cache.

It seems like the "fetcher" is trying to append "petalinux", "aarch64" and other similar strings if the FILESEXTRAPATHS_prepend is not "files.
Can anyone advise if my FILESEXTRAPATHS_prepend is wrong?
