Compile a source file into a libtool library object.

  -no-suppress      do not suppress compiler output for multiple passes
  -prefer-pic       try to building PIC objects only

COMPILE-COMMAND is a command to be used in creating a \`standard' object file

SOURCEFILE, then substituting the C source code suffix \`.c' with the
library object suffix, \`.lo'."

This mode sets the library path environment variable according to \`-dlopen'
flags.

If any of the ARGS are libtool executable wrappers, then they are translated
into their corresponding uninstalled binary, and any of their required library
directories are added to the library path.

Link object files or libraries together to form another library, or to

LINK-COMMAND is a command using the C compiler that you would use to create
a program from several object files.

The following components of LINK-COMMAND are treated specially:

  -all-static       do not do any dynamic linking at all
  -avoid-version    do not add a version suffix if possible
  -dlopen FILE      \`-dlpreopen' FILE if it cannot be dlopened at runtime

		    try to export only the symbols listed in SYMFILE
  -export-symbols-regex REGEX
		    try to export only the symbols matching REGEX
  -LLIBDIR          search LIBDIR for required installed libraries
  -lNAME            OUTPUT-FILE requires the installed library libNAME
  -module           build a library that can dlopened
  -no-fast-install  disable the fast-install mode
  -no-install       link a not-installable executable
  -no-undefined     declare that a library does not refer to external symbols
  -o OUTPUT-FILE    create OUTPUT-FILE from the specified objects
  -objectlist FILE  Use a list of object files found in FILE to specify objects
  -precious-files-regex REGEX

  -release RELEASE  specify package release information
  -rpath LIBDIR     the created library will eventually be installed in LIBDIR
  -R[ ]LIBDIR       add LIBDIR to the runtime path of programs and libraries
  -shared           only do dynamic linking of libtool libraries
  -shrext SUFFIX    override the standard shared library file extension
  -static           do not do any dynamic linking of libtool libraries
  -version-info CURRENT[:REVISION[:AGE]]
		    specify library version info [each variable defaults to 0]
  -weak LIBNAME     declare that the target provides the LIBNAME interface

All other options (arguments beginning with \`-') are ignored.

Every other argument is treated as a filename.  Files ending in \`.la' are
treated as uninstalled libtool libraries, other files are standard or library
object files.

If the OUTPUT-FILE ends in \`.la', then a libtool library is created,
only library objects (\`.lo' files) may be specified, and \`-rpath' is
required, except when creating a convenience library.

If OUTPUT-FILE ends in \`.a' or \`.lib', then a standard library is created
using \`ar' and \`ranlib', or on Windows using \`lib'.

If OUTPUT-FILE ends in \`.lo' or \`.${objext}', then a reloadable object file
is created, otherwise an executable program is created."
