Usage: $progname [OPTION]... LTMAIN [HOST]
259
260
Generate a system-specific libtool script.
261
262
--build configure for building on BUILD [BUILD=HOST]
263
--debug enable verbose shell tracing
264
--disable-shared do not build shared libraries
265
--disable-static do not build static libraries
266
--disable-fast-install do not optimize for fast installation
267
--enable-dlopen enable dlopen support
268
--enable-win32-dll enable building dlls on win32 hosts
269
--help display this help and exit
270
--no-verify do not verify that HOST is a valid host type
271
-o, --output=FILE specify the output file [default=$default_ofile]
272
--quiet same as \`--silent'
273
--silent do not print informational messages
274
--srcdir=DIR find \`config.guess' in DIR
275
--version output version information and exit
276
--with-gcc assume that the GNU C compiler will be used
277
--with-gnu-ld assume that the C compiler uses the GNU linker
278
--prefer-pic try to use only PIC objects
279
--prefer-non-pic try to use only non-PIC objects
280
--disable-lock disable file locking
281
--cache-file=FILE configure cache file
282
283
LTMAIN is the \`ltmain.sh' shell script fragment or \`ltmain.c' program
284
that provides basic libtool functionality.
285
286
HOST is the canonical host system name [default=guessed].
