FILESEXTRAPATHS_prepend problem when building kernel module

Jump to solution

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.
WARNING: /pathtoproject/project-spec/meta-user/recipes-modules/rx/rx.bb: Unable to get checksum for rx SRC_URI entry Makefile: file could not be found | ETA: --:--:--

WARNING: /pathtoproject/project-spec/meta-user/recipes-modules/rx/rx.bb: Unable to get checksum for rx SRC_URI entry rx_driver.h: file could not be found

And later:

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?

Hi

$(THISDIR) is wrong

It should be modified to ${THISDIR}

Excellent.  I knew that.  I was just testing you.  You win the prize!
