[gst-devel] c++ patch

[Brent Bradburn]

Tim,

You error would seem to be consistent with using a version of gstcaps prior to 1.18.
Perhaps you have multiple versions existing on your system.  My first guess would be that you have an installed copy (probably
in /usr/local/include/gst/) which is different from the version that you just got from CVS.

I am keying off the following line:
/opt/gstreamer-cvs/include/gst/gstcaps.h:65: parse error before `typeid'

This matches the code from 1.17 which had a parameter named typeid on line 65.
In 1.18, this has been commented out and is now on line 69.

-Brent
