Usage: $[0] [[OPTION]]... [[VAR=VALUE]]...
909
[To assign environment variables (e.g., CC, CFLAGS...), specify them as
910
VAR=VALUE. See below for descriptions of some of the useful variables.
912
Defaults for the options are specified in brackets.
915
-h, --help display this help and exit
916
--help=short display options specific to this package
917
--help=recursive display the short help of all the included packages
918
-V, --version display version information and exit
919
-q, --quiet, --silent do not print \`checking...' messages
920
--cache-file=FILE cache test results in FILE [disabled]
921
-C, --config-cache alias for \`--cache-file=config.cache'
922
-n, --no-create do not create output files
923
--srcdir=DIR find the sources in DIR [configure dir or \`..']
928
Installation directories:
929
--prefix=PREFIX install architecture-independent files in PREFIX
931
--exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
934
By default, \`make install' will install all the files in
935
\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
936
an installation prefix other than \`$ac_default_prefix' using \`--prefix',
937
for instance \`--prefix=\$HOME'.
939
For better control, use the options below.
