261 Generate a system-specific libtool script.
263 --build configure for building on BUILD [BUILD=HOST]
264 --debug enable verbose shell tracing
265 --disable-shared do not build shared libraries
266 --disable-static do not build static libraries
267 --disable-fast-install do not optimize for fast installation
268 --enable-dlopen enable dlopen support
269 --enable-win32-dll enable building dlls on win32 hosts
270 --help display this help and exit
271 --no-verify do not verify that HOST is a valid host type
272 -o, --output=FILE specify the output file [default=$default_ofile]
273 --quiet same as \`--silent'
274 --silent do not print informational messages
275 --srcdir=DIR find \`config.guess' in DIR
276 --version output version information and exit
277 --with-gcc assume that the GNU C compiler will be used
278 --with-gnu-ld assume that the C compiler uses the GNU linker
279 --prefer-pic try to use only PIC objects
280 --prefer-non-pic try to use only non-PIC objects
281 --disable-lock disable file locking
282 --cache-file=FILE configure cache file
284 LTMAIN is the \`ltmain.sh' shell script fragment or \`ltmain.c' program
285 that provides basic libtool functionality.
287 HOST is the canonical host system name [default=guessed].
