- `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]
- --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]

- Some influential environment variables:

- 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 C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
- you have headers in a nonstandard directory <include dir>
- CPP C preprocessor
- PKG_CONFIG path to pkg-config utility
- SDL_CFLAGS C compiler flags for SDL, overriding pkg-config
- SDL_LIBS linker flags for SDL, 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.
