[Bug java/30035] New: libjava cannot be built when objdir != srcdir

["gcc-bugzilla at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

        "Installing GCC" [1] explicitly encourages building the source code
        with objdir separate from srcdir.

        [1] http://gcc.gnu.org/install/configure.html

        In particular:

            mkdir objdir
            cd objdir
            srcdir/configure [options] [target]

        Most of gcc builds fine that way except libjava, which fails to build
        because:

         1. It does not attempt to create a sub directory for nor configure
            libltdl at all.

         2. libjava/libltdl/config.sub assumes that ../../config.sub can be
            found. The intention is to use srcdir/config.sub, but it cannot
            be refered to this way when objdir != srcdir.

Environment:
System: SunOS types 5.7 Generic_106541-24 sun4u sparc SUNW,Ultra-250
Architecture: sun4


        these are not relevant
host: sparc-sun-solaris2.7
build: sparc-sun-solaris2.7
target: sparc-sun-solaris2.7
configured with: ../gcc-4.1.1/configure --enable-languages=c,c++ --with-gnu-as
--with-gnu-ld --prefix=/cs/church-data/gcc

How-To-Repeat:
        Build gcc with at least --enable-languages=java, in a separate objdir
        than srcdir.


------- Comment #1 from liulk at types dot bu dot edu  2006-12-01 04:16 -------
Fix:
        A Makefile target in libjava should be devised to configure libltdl
        first, and the relative path should be fixed somehow.
