All,
I'm trying to build a small rootfs for my nslu2 project. I have the
basics built ($SYSROOT != $ROOT), but when I go to add app-misc/screen,
the configure stage of the build fails with the following:
### begin error msg ###
# xmerge --root ${TGTROOT} -av screen
...

### end error msg ###
I've seen this happen with older versions of libssl in the gumstix
buildroot when I tried to manually upgrade it. iirc, there is a way to
properly fix it. Most google results suggest adding a 'config.cache'
with the variables for problematic tests already assigned, or exporting
them before merging. I'd prefer to fix the configure scripts.
I can't be the first person who wanted to cross-compile screen. :-)
Am I missing something?
