| dnl Look for the PIC library first, Debian requires it. |
| dnl Check debian-devel archives for gory details. |
| dnl 20020110: |
| dnl At the moment XFree86 doesn't distribute shared libXv due |
| dnl to unstable API. On many platforms you CAN NOT link a shared |
| dnl lib to a static non-PIC lib. This is what the xvideo GStreamer |
| dnl plug-in wants to do. So Debian distributes a PIC compiled |
| dnl version of the static lib for plug-ins to link to when it is |
| dnl inappropriate to link the main application to libXv directly. |
| dnl FIXME: add check if this platform can support linking to a |
| dnl non-PIC libXv, if not then don not use Xv. |
| dnl FIXME: perhaps warn user if they have a shared libXv since |
| dnl this is an error until XFree86 starts shipping one |
