Hi All,
I am attempting to get the AVR Toolchain working inside of Yocto, but
unfortunately I'm relatively new to Yocto and keep seeing various errors I
cannot resolve. I was able to follow the instructions
HERE<http://www.nongnu.org/avr-libc/user-manual/install_tools.html> to get
everything working locally, but I'm seeing various issues inside of Yocto. I
was able to get binutils configured and installed correctly but I haven't had
any luck getting GCC installed. I am able to get pass the configure and compile
stages in Yocto, but when I get to the install task, there's always a failure.
The failure stems from this task below, which is a part of GCC:
# Add unwind.h, it comes from libgcc which we don't want to build again
install
/build-bundle/poky/build/tmp/sysroots/x86_64-linux/usr/lib/avr/gcc/avr/4.9.3/include/unwind.h
/build-bundle/poky/build/tmp/work/cortexa53-vfp-neon-poky-linux-gnueabi/gcc-target-avr/4.9.3-r0/image/usr/lib/gcc/avr/4.9.3/include/
The reason it fails is because one of the two paths is always incorrect, no
matter how I attempt to configure the build. If I configure the TARGET_SYS to
be 'avr' during the install task, the path to 'unwind.h' becomes what is shown
above, but the unwind header is not there. I *think* it's due to the fact that
the TARGET_SYS was set to our default 'arm-poky-linux-gnueabi' during the
configure stage. If I try to set the configuration to have a TARGET_SYS of
'avr' it might resolve the issue, but unfortunately doing this causes the
compile stage to fail with:
| Makefile:1571: t-oe: No such file or directory
| make[1]: *** No rule to make target `t-oe'. Stop.
I am using a slightly modified version of the recipes shown in the link below.

Lastly, here is a link to the GCC commit that talks about the need to copy over
the file that is causing issues for me:
https://gcc.gnu.org/ml/gcc-patches/2003-03/msg00367.html
Thanks in advance for any help you can give, and I apologize if any of this is
unclear, I am still relatively new to Yocto.
Kind Regards,
David Washburn
