MODE must be one of the following:

clean
remove files from the build directory
compile
compile a source file into a libtool object
execute
automatically set library path, then run a program
finish
complete the installation of libtool libraries
install
install libraries or executables
link
create a library or an executable
uninstall
remove libraries from an installed directory

MODE-ARGS vary depending on the MODE. When passed as first option, `--mode=MODE' may be abbreviated as `MODE' or a unique abbreviation of that.

Description of compile mode:

Compile a source file into a libtool library object.

This mode accepts the following additional options:

-o OUTPUT-FILE
set the output file name to OUTPUT-FILE
-no-suppress
do not suppress compiler output for multiple passes
-prefer-pic
try to build PIC objects only
-prefer-non-pic
try to build non-PIC objects only
-shared
do not build a `.o' file suitable for static linking
-static
only build a `.o' file suitable for static linking
-Wc,FLAG
pass FLAG directly to the compiler

COMPILE-COMMAND is a command to be used in creating a `standard' object file from the given SOURCEFILE.

The output file name is determined by removing the directory component from SOURCEFILE, then substituting the C source code suffix `.c' with the library object suffix, `.lo'.

Description of link mode:

Link object files or libraries together to form another library, or to create an executable program.

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
-bindir BINDIR
specify path to binaries directory (for systems where libraries must be found in the PATH setting at runtime)
-dlopen FILE
`-dlpreopen' FILE if it cannot be dlopened at runtime
-dlpreopen FILE
link in FILE and add its symbols to lt_preloaded_symbols
-export-dynamic
allow symbols from OUTPUT-FILE to be resolved with dlsym(3)
-export-symbols SYMFILE
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
don't remove output files matching 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 uninstalled libtool libraries
-static-libtool-libs
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
-Wc,FLAG
-Xcompiler FLAG
pass linker-specific FLAG directly to the compiler
-Wl,FLAG
-Xlinker FLAG
pass linker-specific FLAG directly to the linker
-XCClinker FLAG
pass link-specific FLAG to the compiler driver (CC)

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 `.o', then a reloadable object file is created, otherwise an executable program is created.

Description of execute mode:

Automatically set library path, then run a program.

This mode accepts the following additional options:

-dlopen FILE
add the directory containing FILE to the library path

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.

Then, COMMAND is executed, with ARGS as arguments.

Description of install mode:

Install executables or libraries.

INSTALL-COMMAND is the installation command. The first component should be either the `install' or `cp' program.

The following components of INSTALL-COMMAND are treated specially:

-inst-prefix-dir PREFIX-DIR
Use PREFIX-DIR as a staging area for installation

The rest of the components are interpreted as arguments to that command (only BSD-compatible install options are recognized).

Description of finish mode:

Complete the installation of libtool libraries.

Each LIBDIR is a directory that contains libtool libraries.

The commands that this mode executes may require superuser privileges. Use the `--dry-run' option if you just want to see what would be executed.

Description of uninstall mode:

Remove libraries from an installation directory.

RM is the name of the program to use to delete files associated with each FILE (typically `/bin/rm'). RM-OPTIONS are options (such as `-f') to be passed to RM.

If FILE is a libtool library, all the files associated with it are deleted. Otherwise, only FILE itself is deleted using RM.

Description of clean mode:

Remove files from the build directory.

RM is the name of the program to use to delete files associated with each FILE (typically `/bin/rm'). RM-OPTIONS are options (such as `-f') to be passed to RM.

If FILE is a libtool library, object or program, all the files associated with it are deleted. Otherwise, only FILE itself is deleted using RM.
