1258\`configure' configures nanovis 1.1 to adapt to many kinds of systems.
1259
1260Usage: $0 [OPTION]... [VAR=VALUE]...
1261
1262To assign environment variables (e.g., CC, CFLAGS...), specify them as
1263VAR=VALUE.  See below for descriptions of some of the useful variables.
1264
1265Defaults for the options are specified in brackets.
1266
1267Configuration:
1268  -h, --help              display this help and exit
1269      --help=short        display options specific to this package
1270      --help=recursive    display the short help of all the included packages
1271  -V, --version           display version information and exit
1272  -q, --quiet, --silent   do not print \`checking ...' messages
1273      --cache-file=FILE   cache test results in FILE [disabled]
1274  -C, --config-cache      alias for \`--cache-file=config.cache'
1275  -n, --no-create         do not create output files
1276      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1277
1278Installation directories:
1279  --prefix=PREFIX         install architecture-independent files in PREFIX
1280                          [$ac_default_prefix]
1281  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1282                          [PREFIX]
1283
1284By default, \`make install' will install all the files in
1285\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1286an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1287for instance \`--prefix=\$HOME'.
1288
1289For better control, use the options below.

1291Fine tuning of the installation directories:
1292  --bindir=DIR            user executables [EPREFIX/bin]
1293  --sbindir=DIR           system admin executables [EPREFIX/sbin]

1337  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a

1339  LIBS        libraries to pass to the linker, e.g. -l<library>
1340  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1341              you have headers in a nonstandard directory <include dir>
1342  CPP         C preprocessor
1343  CXX         C++ compiler command
1344  CXXFLAGS    C++ compiler flags
1345  CXXCPP      C++ preprocessor
1346
1347Use these variables to override the choices made by `configure' or to help
1348it to find libraries and programs with nonstandard names/locations.
