| \`configure' configures GNU C Library (see version.h) to adapt to many kinds of systems. |
| |
| Usage: $0 [OPTION]... [VAR=VALUE]... |
| |
| To assign environment variables (e.g., CC, CFLAGS...), specify them as |
| VAR=VALUE. See below for descriptions of some of the useful variables. |
| |
| Defaults for the options are specified in brackets. |
| |
| Configuration: |
| -h, --help display this help and exit |
| --help=short display options specific to this package |
| --help=recursive display the short help of all the included packages |
| -V, --version display version information and exit |
| -q, --quiet, --silent do not print \`checking ...' messages |
| --cache-file=FILE cache test results in FILE [disabled] |
| -C, --config-cache alias for \`--cache-file=config.cache' |
| -n, --no-create do not create output files |
| --srcdir=DIR find the sources in DIR [configure dir or \`..'] |
| |
| Installation directories: |
| --prefix=PREFIX install architecture-independent files in PREFIX |
| [$ac_default_prefix] |
| --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX |
| [PREFIX] |
| |
| By default, \`make install' will install all the files in |
| \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify |
| an installation prefix other than \`$ac_default_prefix' using \`--prefix', |
| for instance \`--prefix=\$HOME'. |
| |
| For better control, use the options below. |
| |
| Fine tuning of the installation directories: |
| --bindir=DIR user executables [EPREFIX/bin] |
| --sbindir=DIR system admin executables [EPREFIX/sbin] |
| --libexecdir=DIR program executables [EPREFIX/libexec] |
| --sysconfdir=DIR read-only single-machine data [PREFIX/etc] |
| --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com] |
| --localstatedir=DIR modifiable single-machine data [PREFIX/var] |
| --libdir=DIR object code libraries [EPREFIX/lib] |
| --includedir=DIR C header files [PREFIX/include] |
| --oldincludedir=DIR C header files for non-gcc [/usr/include] |
| --datarootdir=DIR read-only arch.-independent data root [PREFIX/share] |
| --datadir=DIR read-only architecture-independent data [DATAROOTDIR] |
| --infodir=DIR info documentation [DATAROOTDIR/info] |

| --disable-build-nscd disable building and installing the nscd daemon |
| --disable-nscd library functions will not contact the nscd daemon |
| --enable-pt_chown Enable building and installing pt_chown |
| |
| Optional Packages: |
| --with-PACKAGE[=ARG] use PACKAGE [ARG=yes] |
| --without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no) |
| --with-pkgversion=PKG Use PKG in the version string in place of "GNU libc" |

| --with-gd-lib=DIR find libgd library files in DIR |
| --with-fp if using floating-point hardware [default=yes] |
| --with-binutils=PATH specify location of binutils (as and ld) |
| --with-selinux if building with SELinux support |
| --with-headers=PATH location of system headers to use (for example |
| /usr/src/linux/include) [default=compiler default] |
| --with-default-link do not use explicit linker scripts |
| --with-cpu=CPU select code for CPU variant |
| |
| Some influential environment variables: |
| CC C compiler command |
| CFLAGS C compiler flags |
| LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a |
| nonstandard directory <lib dir> |
| LIBS libraries to pass to the linker, e.g. -l<library> |
| CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if |
| you have headers in a nonstandard directory <include dir> |
| CPP C preprocessor |
| CXX C++ compiler command |
| CXXFLAGS C++ compiler flags |
| |
| Use these variables to override the choices made by `configure' or to help |
| it to find libraries and programs with nonstandard names/locations. |
