Hello openembedded community!

I hope this is the right place to ask this question, https://wiki.yoctoproject.org/wiki/Pseudo_Abort ( https://wiki.yoctoproject.org/wiki/Pseudo_Abort ) brought me here.

I have a custom recipe which builds fine on the first build, but fails on subsequent builds in the do_install step:

Yocto is the only one touching the files in between builds. Also the files questioned do exist with the noted inode:

I am doing nothing unusual here.

Additional notes to my setup:

* Host machine: Ubuntu 22.04 on WSL
* Linux kernel: linux-imx (NXP)

Does someone have an idea what is happening here? Any help is appreciated!

Kind regards,

Lukas Palme

Don't use:
S = "${WORKDIR}"

move it to separate directory and it will work fine.

Hi

thanks you for the tips. I had to tell the fetcher to unpack into ${S} too:

> 
> SRC_URI = "file://Makefile;subdir=${S} \
> file://mymodule_core.c;subdir=${S} \
> file://mymodule.h;subdir=${S} \
> file://mymodule_public.h;subdir=${S} \
> file://mymodule_remote_public.h;subdir=${S} \
> "
> 
> S = "${WORKDIR}/checkout"

and it worked like a charm :)
