-n, –dry-run

–quiet, –silent

don’t print informational messages

–no-quiet, –no-silent

print informational messages (default)

-v, –verbose

–no-verbose

-h, –help, –help-all

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.
