247 --disable-static do not build static libraries
248 --disable-fast-install do not optimize for fast installation
249 --enable-dlopen enable dlopen support
250 --enable-win32-dll enable building dlls on win32 hosts
251 --help display this help and exit
252 --no-verify do not verify that HOST is a valid host type
253 -o, --output=FILE specify the output file [default=$default_ofile]
254 --quiet same as \`--silent'
255 --silent do not print informational messages
256 --srcdir=DIR find \`config.guess' in DIR
257 --version output version information and exit
258 --with-gcc assume that the GNU C compiler will be used
259 --with-gnu-ld assume that the C compiler uses the GNU linker
260 --disable-lock disable file locking
261 --cache-file=FILE configure cache file
262
263 LTMAIN is the \`ltmain.sh' shell script fragment or \`ltmain.c' program
264 that provides basic libtool functionality.
