Hi
Sounds a lot like this:
https://www.spinics.net/lists/arm-kernel/msg712490.html
and the solution is there as well. But I don't know where to put this
flag in adk.
And I don't know how to fix this otherwise. Updating the kernel to
5.0.7, glibc to 2.29, mpfr to 4.0.2 and llvm to 7.0.1 did not help...
The patch below makes it build, but trying to boot gives a kernel panic,
so I guess this is not the right way.
Can anyone help?
Thanks
Oliver

Hi again
It looks like this is a problem with gcc 8. The kernel won't build,
neither with uglibc-ng nor with glibc selected. Also not with gcc
version git.
gcc 7 builds fine and boots, (arm, raspberry pi 3 model b+, new
appliance, kernel and bootloader updated as per my patch).
Build is possible on gcc 8 when choosing aarch64. Unfortunately, this
does not boot (rainbow screen, can't ping).
Any ideas how to make gcc 8 work?
