| \`configure' configures this package 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] |
| --runstatedir=DIR modifiable per-process data [LOCALSTATEDIR/run] |
| --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] |
| --localedir=DIR locale-dependent data [DATAROOTDIR/locale] |
| --mandir=DIR man documentation [DATAROOTDIR/man] |
| --docdir=DIR documentation root [DATAROOTDIR/doc/PACKAGE] |
| --htmldir=DIR html documentation [DOCDIR] |
| --dvidir=DIR dvi documentation [DOCDIR] |
| --pdfdir=DIR pdf documentation [DOCDIR] |

| Optional Features: |
| --disable-option-checking ignore unrecognized --enable/--with options |
| --disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no) |
| --enable-FEATURE[=ARG] include FEATURE [ARG=yes] |
| --disable-sdltest Do not try to compile and run a test SDL program |
| |
| Optional Packages: |
| --with-PACKAGE[=ARG] use PACKAGE [ARG=yes] |
| --without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no) |
| --with-sdl-prefix=PFX Prefix where SDL is installed (optional) |
| --with-sdl-exec-prefix=PFX Exec prefix where SDL is installed (optional) |
| --with-x use the X Window System |
| |
| 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> |
| PKG_CONFIG path to pkg-config utility |
| PKG_CONFIG_PATH |
| directories to add to pkg-config's search path |
| PKG_CONFIG_LIBDIR |
| path overriding pkg-config's built-in search path |
| SDL_CFLAGS C compiler flags for SDL, overriding pkg-config |
| SDL_LIBS linker flags for SDL, overriding pkg-config |
| XMKMF Path to xmkmf, Makefile generator for X Window System |
| CPP C preprocessor |
| LIBUNWIND_CFLAGS |
| C compiler flags for LIBUNWIND, overriding pkg-config |
| LIBUNWIND_LIBS |
| linker flags for LIBUNWIND, overriding pkg-config |
| |
| Use these variables to override the choices made by `configure' or to help |
| it to find libraries and programs with nonstandard names/locations. |
| |
| Report bugs to the package provider. |
