311 Usage: $progname [OPTION]... LTMAIN [HOST]
313 Generate a system-specific libtool script.
315 --build configure for building on BUILD [BUILD=HOST]
316 --debug enable verbose shell tracing
317 --disable-shared do not build shared libraries
318 --disable-static do not build static libraries
319 --disable-fast-install do not optimize for fast installation
320 --enable-dlopen enable dlopen support
321 --enable-win32-dll enable building dlls on win32 hosts
322 --help display this help and exit
323 --no-verify do not verify that HOST is a valid host type
324 -o, --output=FILE specify the output file [default=$default_ofile]
325 --quiet same as \`--silent'
326 --silent do not print informational messages
327 --srcdir=DIR find \`config.guess' in DIR
328 --version output version information and exit
329 --add-tag=TAG append an alternate configuration
330 --with-gcc assume that the GNU C compiler will be used
331 --with-gnu-ld assume that the C compiler uses the GNU linker
332 --prefer-pic try to use only PIC objects
333 --prefer-non-pic try to use only non-PIC objects
334 --disable-lock disable file locking
335 --cache-file=FILE configure cache file
337 LTMAIN is the \`ltmain.sh' shell script fragment or \`ltmain.c' program
338 that provides basic libtool functionality.
340 HOST is the canonical host system name [default=guessed].
