NetBSD ultra 2.0_BETA NetBSD 2.0_BETA (GENERIC) #0: Thu May 20 18:40:11 UTC 2004  autobuild@tgm.netbsd.org:/autobuild/netbsd-2-0/sparc64/OBJ/autobuild/netbsd-2-0/src/sys/arch/sparc64/compile/GENERIC sparc64
>Description:
Trying to cross-compile a kernel from sparc64 for my sparc (32-bit) Voyager with all the PCMCIA goodies available.

>How-To-Repeat:
./build.sh -O /usr/src/obj/sparc -T /usr/src/cross/sparc -m sparc -u kernel=VGER

where the primary difference between VGER and GENERIC is the uncommenting of:
wdc*    at pcmcia?
atabus* at ata?
wd*     at atabus? drive ? flags 0x0000

>Fix:
Well, I tried compiling the problematic file without -Werror, but it gave up when trying to link the kernel at the end:
#      link  VGER/netbsd
/usr/src/cross/sparc/bin/sparc--netbsdelf-ld -n -T /usr/src/src/sys/arch/sparc/c
onf/kern.ldscript -Ttext F0004000 -e start -X -S -o netbsd ${SYSTEM_OBJ} ${EXTRA
