That's not really the responsibility of the autotools folks. Say I write a pacakge that uses ac_cv_has_gstreamer which for my pckage means "gst-inspect is present". Now you have no knowledge of my package, and you write your own package that uses ac_cv_has_gstreamer which would mean "libgstreamer.so.0 is present and usable". There is no reconciliation possible betwen your package and mine. That's not the fault of the autotools. Maybe we could say that it's the fault of gstreamer to not provide the adequate macros, but even if that was the case, that would not prevent two packages to use the same variable to represent two different things (think optinal behaviour depending on the environment for a package, while another would use it to represent a user-selectable --enable/disable option). There's no way out of this mess... Regards, Yann E. MORIN. -- .-----------------.--------------------.------------------.--------------------. | Yann E.
