since the "parisc: Add vDSO support" commit, I can no longer
cross-build a hppa kernel. I see two issues:
1) CROSS32_COMPILE detection doesn't work here, as openSUSE
provides hppa-suse-linux-* binaries. It's easy to overcome by
"CROSS32_COMPILE=hppa-suse-linux-"
...
Would it make sense to add the detection for SUSE too?
So, could 1) be fixed on the Kconfig side? Or should I (people running SUSE)
use "CROSS32_COMPILE=hppa-suse-linux-"?
Could you please try if this patch fixes it for you?
Works like a charm:
$ make V=1 O=../a/arch/parisc/ ARCH=parisc -j6 drivers/tty/serial/mux.o
...
> hppa-suse-linux-gcc <flags deleted> -o drivers/tty/serial/mux.o
/home/latest/linux/drivers/tty/serial/mux.c
> if hppa-suse-linux-objdump -h drivers/tty/serial/mux.o | ...; fi
Thanks.
