 1351 \`configure' configures singular_resources 4.2.1 to adapt to many kinds of systems.
 1352 
 1353 Usage: $0 [OPTION]... [VAR=VALUE]...
 1354 
 1355 To assign environment variables (e.g., CC, CFLAGS...), specify them as
 1356 VAR=VALUE.  See below for descriptions of some of the useful variables.
 1357 
 1358 Defaults for the options are specified in brackets.
 1359 
 1360 Configuration:
 1361   -h, --help              display this help and exit
 1362       --help=short        display options specific to this package
 1363       --help=recursive    display the short help of all the included packages
 1364   -V, --version           display version information and exit
 1365   -q, --quiet, --silent   do not print \`checking ...' messages
 1366       --cache-file=FILE   cache test results in FILE [disabled]
 1367   -C, --config-cache      alias for \`--cache-file=config.cache'
 1368   -n, --no-create         do not create output files
 1369       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
 1370 
 1371 Installation directories:
 1372   --prefix=PREFIX         install architecture-independent files in PREFIX
 1373                           [$ac_default_prefix]
 1374   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
 1375                           [PREFIX]
 1376 
 1377 By default, \`make install' will install all the files in
 1378 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
 1379 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
 1380 for instance \`--prefix=\$HOME'.
 1381 
 1382 For better control, use the options below.
 1383 
 1384 Fine tuning of the installation directories:
 1385   --bindir=DIR            user executables [EPREFIX/bin]

 1452   --with-pic[=PKGS]       try to use only PIC/non-PIC objects [default=use
 1453                           both]
 1454   --with-aix-soname=aix|svr4|both
 1455                           shared library versioning (aka "SONAME") variant to
 1456                           provide on AIX, [default=aix].

 1458   --with-sysroot[=DIR]    Search for dependent libraries within DIR (or the
 1459                           compiler's sysroot if not specified).
 1460 
 1461 Some influential environment variables:
 1462   CC          C compiler command
 1463   CFLAGS      C compiler flags
 1464   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
 1465               nonstandard directory <lib dir>
 1466   LIBS        libraries to pass to the linker, e.g. -l<library>
 1467   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
 1468               you have headers in a nonstandard directory <include dir>
 1469   CXX         C++ compiler command
 1470   CXXFLAGS    C++ compiler flags
 1471   CPP         C preprocessor
 1472   LT_SYS_LIBRARY_PATH
 1473               User-defined run-time library search path.
 1474   CXXCPP      C++ preprocessor
 1475 
 1476 Use these variables to override the choices made by `configure' or to help
 1477 it to find libraries and programs with nonstandard names/locations.

 3030 Oops!
 3031 
 3032 Your 'rm' program seems unable to run without file operands specified
 3033 on the command line, even when the '-f' option is present.  This is contrary
 3034 to the behaviour of most rm programs out there, and not conforming with
 3035 the upcoming POSIX standard: <http://austingroupbugs.net/view.php?id=542>
 3036 
 3037 Please tell bug-automake@gnu.org about your system, including the value
 3038 of your $PATH and any error possibly output before this message.  This
 3039 can help us improve future automake versions.
