 1448 \`configure' configures factory 4.2.1 to adapt to many kinds of systems.
 1449 
 1450 Usage: $0 [OPTION]... [VAR=VALUE]...
 1451 
 1452 To assign environment variables (e.g., CC, CFLAGS...), specify them as
 1453 VAR=VALUE.  See below for descriptions of some of the useful variables.
 1454 
 1455 Defaults for the options are specified in brackets.
 1456 
 1457 Configuration:
 1458   -h, --help              display this help and exit
 1459       --help=short        display options specific to this package
 1460       --help=recursive    display the short help of all the included packages
 1461   -V, --version           display version information and exit
 1462   -q, --quiet, --silent   do not print \`checking ...' messages
 1463       --cache-file=FILE   cache test results in FILE [disabled]
 1464   -C, --config-cache      alias for \`--cache-file=config.cache'
 1465   -n, --no-create         do not create output files
 1466       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
 1467 
 1468 Installation directories:
 1469   --prefix=PREFIX         install architecture-independent files in PREFIX
 1470                           [$ac_default_prefix]
 1471   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
 1472                           [PREFIX]
 1473 
 1474 By default, \`make install' will install all the files in
 1475 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
 1476 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
 1477 for instance \`--prefix=\$HOME'.
 1478 
 1479 For better control, use the options below.

 1482   --bindir=DIR            user executables [EPREFIX/bin]

 1563 Optional Packages:
 1564   --with-PACKAGE[=ARG]    use PACKAGE [ARG=yes]
 1565   --without-PACKAGE       do not use PACKAGE (same as --with-PACKAGE=no)
 1566   --with-pic[=PKGS]       try to use only PIC/non-PIC objects [default=use
 1567                           both]
 1568   --with-aix-soname=aix|svr4|both
 1569                           shared library versioning (aka "SONAME") variant to
 1570                           provide on AIX, [default=aix].
 1571   --with-gnu-ld           assume the C compiler uses GNU ld [default=no]
 1572   --with-sysroot[=DIR]    Search for dependent libraries within DIR (or the
 1573                           compiler's sysroot if not specified).
 1574   --without-Singular      (obsolete) build NOT for the use with CAS Singular.
 1575   --with-gmp=path         provide a non-standard location of gmp
 1576   --with-ntl=<path>|yes|no  Use NTL library. If argument is no, you do not have
 1577                             the library installed on your machine (set as
 1578                 default). If argument is yes or <empty> that means
 1579                 the library is reachable with the standard search
 1580                 path (/usr or /usr/local). Otherwise you give the
 1581                 <path> to the directory which contain the library.
 1582 
 1583   --with-flint=<path>|yes|no  Use FLINT library. By default (yes), Singular will
 1584                             try to find the library and use it if found.
 1585                             If argument is no, Singular will not use the
 1586                             library even if it could be found on your machine.
 1587                             Otherwise you can give the <path> to the directory
 1588                             which contains the library.
 1589 
 1590 
 1591 Some influential environment variables:
 1592   CC          C compiler command
 1593   CFLAGS      C compiler flags
 1594   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
 1595               nonstandard directory <lib dir>
 1596   LIBS        libraries to pass to the linker, e.g. -l<library>
 1597   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
 1598               you have headers in a nonstandard directory <include dir>
 1599   CPP         C preprocessor
 1600   CXX         C++ compiler command
 1601   CXXFLAGS    C++ compiler flags

 1604               Defaults to the first program found out of: `bison -y', `byacc',
 1605               `yacc'.
 1606   YFLAGS      The list of arguments that will be passed by default to $YACC.
 1607               This script will default YFLAGS to the empty string to avoid a
 1608               default value of `-d' given by some make applications.
 1609   LT_SYS_LIBRARY_PATH
 1610               User-defined run-time library search path.
 1611   OMALLOC_INCLUDES
 1612               INCLUDES for libomalloc
 1613   OMALLOC_LIBS
 1614               LIBS for libomalloc
 1615   RESOURCES_INCLUDES
 1616               INCLUDES for libsingular_resources
 1617   RESOURCES_LIBS
 1618               LIBS for libsingular_resources
 1619   DOXYGEN_PAPER_SIZE
 1620               a4wide (default), a4, letter, legal or executive
 1621 
 1622 Use these variables to override the choices made by `configure' or to help
 1623 it to find libraries and programs with nonstandard names/locations.
