Hi,
I suspect it is more likely that i get feedback from people on -current,
which is why this email is addressed there. I am Bcc-ing to -small in
case the people there are interested too.
Basically, i would like to come up with some easy way to cross-build
picobsd images, embedding the relevant commands into the "picobsd"
build script so one only has to specify the SRC tree location and the
script does all things for you.
There are a number of dependencies that need to be addressed in
this process, including at least the following.
1. the config program.
I more or less know how to handle this, basically compile
whatever config is in ${SRC}/usr.sbin/config and use that
one for the config step.
2. location of standard include files.
Here, it looks not too complex -- at the moment i
basically do the following:
cd ${SRC}
mkdir -p usr/include
DESTDIR=`pwd` make includes
CFLAGS="-nostdinc -I`pwd`/usr/includes" ; export CFLAGS
and hope that the various makefiles honor CFLAGS settings.
It seems to work for most things.
3. libraries
This is the hard part for me. I guess there is some way
from the makefiles in ${SRC}/lib to build just the static
libraries and put them in some place where I can use them
without conflict with the standard ones, but how ?
So, could anyone suggest a good way to address step #3 ?
thanks
luigi
