1137     \`configure' configures this package to adapt to many kinds of systems.
1138    
1139     Usage: $0 [OPTION]... [VAR=VALUE]...
1140    
1141     To assign environment variables (e.g., CC, CFLAGS...), specify them as
1142     VAR=VALUE. See below for descriptions of some of the useful variables.
1143    
1144     Defaults for the options are specified in brackets.
1145    
1146     Configuration:
1147     -h, --help display this help and exit
1148     --help=short display options specific to this package
1149     --help=recursive display the short help of all the included packages
1150     -V, --version display version information and exit
1151     -q, --quiet, --silent do not print \`checking...' messages
1152     --cache-file=FILE cache test results in FILE [disabled]
1153     -C, --config-cache alias for \`--cache-file=config.cache'
1154     -n, --no-create do not create output files
1155     --srcdir=DIR find the sources in DIR [configure dir or \`..']
1156    
1157     Installation directories:
1158     --prefix=PREFIX install architecture-independent files in PREFIX
1159     [$ac_default_prefix]
1160     --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
1161     [PREFIX]
1162    
1163     By default, \`make install' will install all the files in
1164     \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
1165     an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1166     for instance \`--prefix=\$HOME'.
1167    
1168     For better control, use the options below.
1169    
1170     Fine tuning of the installation directories:
1171     --bindir=DIR user executables [EPREFIX/bin]
1172     --sbindir=DIR system admin executables [EPREFIX/sbin]
1173     --libexecdir=DIR program executables [EPREFIX/libexec]
1174     --sysconfdir=DIR read-only single-machine data [PREFIX/etc]
1175     --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
1176     --localstatedir=DIR modifiable single-machine data [PREFIX/var]
1177     --libdir=DIR object code libraries [EPREFIX/lib]
1178     --includedir=DIR C header files [PREFIX/include]
1179     --oldincludedir=DIR C header files for non-gcc [/usr/include]

1202     CFLAGS C compiler flags

1204     nonstandard directory <lib dir>
