Hi,
I've figured out all the right flags to pass to a cross-build
environment. Namely:
env CROSS_BUILD_TESTING=YES
MAKEOBJDIRPREFIX=${X_MAKEOBJDIRPREFIX} \
make ${BUILD_FLAGS} TARGET=${TARGET}
TARGET_ARCH=${TARGET_ARCH} \
${X_TARGET_CPUTYPE} KERNCONF=${KERNCONF}
DESTDIR=${X_DESTDIR} \
KODIR=/boot/kernel.${KERNCONF}/
\
KMODDIR=/boot/kernel.${KERNCONF}/
\
__MAKE_CONF=/dev/null SRCCONF=/dev/null
\
LOCAL_DIRS="${LOCAL_DIRS}"
\
LOCAL_TOOL_DIRS="${LOCAL_TOOL_DIRS}" $1
\
.. ignore LOCAL_TOOL_DIRS, I haven't committed that yet to -HEAD.
If someone would like to update picobsd to make this work, I'll
happily test out patches and commit it to -HEAD.
Building -8 and previous needed some extra hacks (eg
TARGET_BIG_ENDIAN) which have been removed from -HEAD/-9.
Good luck!
Adrian
