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