By the look of it, posix is the one you need as include, although you might want to merge in the os directory depending on what layout the apps you want to compile expect. You could do this by making a new 'include' directory and using cpio or similar to link in all the files in os and posix. I don't know the convention for your OS. I may be a few years out of date but it used to be safest to use absolute paths for configure parameters rather than relative paths, i.e. --with-sysroot=/home/mccall/haiku/headers Rup.
