# This configure script is *not* autoconf-based and has different semantics.
# It attempts to autodetect all settings and options where possible. It is
# possible to override autodetection with the --enable-option/--disable-option
# command line parameters.  --enable-option forces the option on skipping
# autodetection. Yes, this means that compilation may fail and yes, this is not
# how autoconf-based configure scripts behave.
#
# configure generates a series of configuration files:
#  - config.h contains #defines that are used in the C code.
#  - config.mak is included from the Makefiles.
#
# If you want to add a new check for $feature, look at the existing checks
# and try to use helper functions where you can.
#
# Furthermore you need to add the variable _feature to the list of default
# settings and set it to one of yes/no/auto. Also add appropriate
# --enable-feature/--disable-feature command line options.
# The results of the check should be written to config.h and config.mak
# at the end of this script. The variable names used for this should be
# uniform, i.e. if the option is named 'feature':
#
# _feature     : should have a value of yes/no/auto
# def_feature  : '#define ... 1' or '#undef ...' for conditional compilation
# ld_feature   : '-L/path/dir -lfeature' GCC options

Language options:
  --charset=charset      convert the console messages to this character set
  --language-doc=lang    language to use for the documentation [en]
  --language-man=lang    language to use for the man pages [en]

  --language=lang        default language to use [en]
Specific options override --language. You can pass a list of languages separated
by whitespace or commas instead of a single language. Nonexisting translations
will be dropped from each list. All documentation and man page translations
available in the list will be installed, for the messages the first available
translation will be used. The value "all" will activate all translations. The
LINGUAS environment variable is honored. In all cases the fallback is English.
Available values are: all $msg_lang_all

Use these options if autodetection fails:
  --extra-cflags=FLAGS        extra CFLAGS
  --extra-ldflags=FLAGS       extra LDFLAGS
  --extra-libs=FLAGS          extra linker flags
  --extra-libs-mplayer=FLAGS  extra linker flags for MPlayer
  --extra-libs-mencoder=FLAGS extra linker flags for MEncoder
  --with-xvmclib=NAME         adapter-specific library name (e.g. XvMCNVIDIA)

  --with-freetype-config=PATH path to freetype-config
  --with-sdl-config=PATH      path to sdl*-config
  --with-dvdnav-config=PATH   path to dvdnav-config
  --with-dvdread-config=PATH  path to dvdread-config

This configure script is NOT autoconf-based, even though its output is similar.
It will try to autodetect all configuration options. If you --enable an option
it will be forcefully turned on, skipping autodetection. This can break
compilation, so you need to know what you are doing.

Check $TMPLOG if you wonder why an autodetection failed (make sure
development headers/packages are installed).

NOTE: The --enable-* parameters unconditionally force options on, completely
skipping autodetection. This behavior is unlike what you may be used to from
autoconf-based configure scripts that can decide to override you. This greater
level of control comes at a price. You may have to provide the correct compiler
and linker flags yourself.
If you used one of these options (except --enable-menu and similar ones that
turn on internal features) and experience a compilation or linking failure,
make sure you have passed the necessary compiler/linker flags to configure.

If you suspect a bug, please read DOCS/HTML/$language_doc/bugreports.html.

MPlayer compilation will use the CPPFLAGS/CFLAGS/LDFLAGS/YASMFLAGS set by you,
but:

    *** ***  DO NOT REPORT BUGS IF IT DOES NOT COMPILE/WORK!  *** ***

It is strongly recommended to let MPlayer choose the correct *FLAGS!
To do so, remove *FLAGS from the environment an re-run configure.
You can use --extra-*flags to add custom flags if necessary.
