to the stock libtool: you can now copy or symlink an uninstalled libtool archive file somewhere else than its build directory, and you can still link against it. This allows us to more easily bolt libtool build machinery onto packages that have unusual(ly crappy) build systems that rely on installing libraries to some common build directory after they're built. We do this by adding a "buildlibdir" variable to the uninstalled libtool archive that points to the build directory of the archive. Whenever we link against this archive, we rewrite the path to archive on the libtool command line so that it points to the true archive. This allows the real libtool to find the files under $buildlibdir/.libs.

# For *.la files, in the "relink_command" line, we make the following
|
|
# replacements:
|
|
#
|
|
# "libfoo.la" -> "-L./.libs libfoo.la"
|
|
# "dirpath/libfoo.la" -> "-Ldirpath/.libs libfoo.la"
|
|
#
|
|
# This allows the libraries to be found within ${WRKSRC} during relinking.
|
|
# We rely on the proper rpath settings to be set by libtool.
|
|
#
|
|
# For the *.lai files, in the "dependency_libs" line, we remove redundant
|
|
# -Ldir and -llib options. We also make sure that we don't ever reference
|
|
# other .la files, only referring to other libraries via the usual
|
|
# "-L/path -llib" and making sure that /path is always somewhere under the
|
|
# default view. This makes wildcard dependencies work for "overwrite"
|
|
# packages by letting libtool find libraries in the default view.
