The problem that I'm having is dealing with interelationships between
the projects. I have one project with 8 sub projects. Several of these
are libraries. The rest of the subpackages depend on these libraries.
The difficult thing is to communicating to the subpackages that build
applications that depend on the libraries where to find the hader
files libraries.
The top level configure script knows that all the libraries are
available and knows where they are. However passing this information
down to the subpackages in such a way that their configure scripts
find everything in the right place is proving very very difficult.
If anyone knows of an application that does this, I would sure be
appriciative. What I have now is:
AC_CHECK_LIB(tdb,tdb_exists,[
build_tdb=false
AC_CHECK_HEADERS(tdb.h,[],[
AC_MSG_ERROR(The tdb libraries were found but the header files were missing.
Please either install the headers or uninstall the library and the version of tdb that
is bundled with gnulpr will be intsalled.)
])],[
ac_configure_args="${ac_configure_args} --enable-local-tdb=${srcdir}/tdb"
subpackages="tdb ${subpackages}"
build_tdb=true
TDB_DIR="${srcdir}/tdb"
])
AM_CONDITIONAL(BUILD_TDB, $build_tdb)
AC_SUBST(TDB_DIR)

This is not true in my experience. If I use Mo's trick and set srcdir
to `cd $srcdir;pwd` or if I remove the special case for '.' then it
still works with no modification to the subpackages configuration
scripts.
