1.4 -dnl Perform a check for a feature for GStreamer
1.5 -dnl Richard Boulton <richard-alsa@tartarus.org>

1.9 -dnl DEPENDENT-PLUGINS, TEST-FOR-FEATURE,
1.10 -dnl DISABLE-BY-DEFAULT, ACTION-IF-USE, ACTION-IF-NOTUSE)
1.11 -dnl
1.12 -dnl This macro adds a command line argument to enable the user to enable
1.13 -dnl or disable a feature, and if the feature is enabled, performs a supplied
1.14 -dnl test to check if the feature is available.
1.15 -dnl
1.16 -dnl The test should define HAVE_<FEATURE-NAME> to "yes" or "no" depending
1.17 -dnl on whether the feature is available.
1.18 -dnl
1.19 -dnl The macro will set USE_<FEATURE-NAME> to "yes" or "no" depending on
1.20 -dnl whether the feature is to be used.
1.21 -dnl Thomas changed this, so that when USE_<FEATURE-NAME> was already set
1.22 -dnl to no, then it stays that way.
1.23 -dnl
1.24 -dnl The macro will call AM_CONDITIONAL(USE_<<FEATURE-NAME>, ...) to allow
1.25 -dnl the feature to control what is built in Makefile.ams. If you want
1.26 -dnl additional actions resulting from the test, you can add them with the
1.27 -dnl ACTION-IF-USE and ACTION-IF-NOTUSE parameters.
1.28 -dnl
1.29 -dnl FEATURE-NAME is the name of the feature, and should be in
1.30 -dnl purely upper case characters.
1.31 -dnl FEATURE-DESCRIPTION is used to describe the feature in help text for
1.32 -dnl the command line argument.
1.33 -dnl DEPENDENT-PLUGINS lists any plugins which depend on this feature.
1.34 -dnl TEST-FOR-FEATURE is a test which sets HAVE_<FEATURE-NAME> to "yes"
1.35 -dnl or "no" depending on whether the feature is
1.36 -dnl available.
1.37 -dnl DISABLE-BY-DEFAULT if "disabled", the feature is disabled by default,
1.38 -dnl if any other value, the feature is enabled by default.
1.39 -dnl ACTION-IF-USE any extra actions to perform if the feature is to be
1.40 -dnl used.
1.41 -dnl ACTION-IF-NOTUSE any extra actions to perform if the feature is not to
1.42 -dnl be used.
