:
: This utility takes a list of libraries in the form
: -llib1 -llib2 -llib3
: and prints out lines suitable for inclusion in an extension
: Makefile.
: Extra library paths may be included with the form -L/another/path
: this will affect the searches for all subsequent libraries.
:
: It is intended to be "dotted" from within an extension Makefile.SH.
: see ext/POSIX/Makefile.SH for an example.
: Prior to calling this, the variable potential_libs should be set
: to the potential list of libraries
:
: It sets the following
: extralibs = full list of libraries needed for static linking.
: Only those libraries that actually exist are included.
: dynaloadlibs = full path names of those libraries that are needed
: but can be linked in dynamically on this platform. On
: SunOS, for example, this would be .so* libraries,
: but not archive libraries.
: Eventually, this list can be used to write a bootstrap file.
: statloadlibs = list of those libraries which must be statically
: linked into the shared library. On SunOS 4.1.3,
: for example, I have only an archive version of
: -lm, and it must be linked in statically.
:
: This script uses config.sh variables libs, libpth, and so. It is mostly
: taken from the metaconfig libs.U unit.
