Hi,
I have been trying to do a "cross-compile" of PicoBSD, ie. use a
source tree different from the installed one. Basically the idea
is to be able to use checked-out sources for, say, 5.0 using 4.x
as build environment.
The tricky point seems to be using a standard include directory
different from /usr/include. I tried setting CFLAGS in the environment
as below, and it seems to work, but I would like some comments from
those of you familiar with the build process.
In any case, I did the following:
# cd to the directory where you extract your source tree
lcvs co -r RELENG_4 src # extract sources ...
lcvs co -r RELENG_4 ports/picobsd # .. and relevant ports
mkdir -p usr/include # include files go here
(setenv DESTDIR=`pwd` ; cd src; make includes) # create include tree
setenv SRC `pwd` # used later by picobsd script
setenv CFLAGS "-nostdinc -I`pwd`/usr/include"
picobsd <floppy-type>
hope this helps...
cheers
luigi
