libtool: Trace interface

1 12 Libtool's trace interface
1 ****************************
1 
1 This section describes macros whose sole purpose is to be traced using
11 Autoconf's '--trace' option (⇒The Autoconf Manual
 (autoconf)autoconf Invocation.) to query the Libtool configuration of a
1 project.  These macros are called by Libtool internals and should never
1 be called by user code; they should only be traced.
1 
1  -- Macro: LT_SUPPORTED_TAG (TAG)
1      This macro is called once for each language enabled in the package.
1      Its only argument, TAG, is the tag-name corresponding to the
1      language (⇒Tags).
1 
1      You can therefore retrieve the list of all tags enabled in a
1      project using the following command:
1           autoconf --trace 'LT_SUPPORTED_TAG:$1'
