[gst-devel] python gstreamer and windows

[Michal Benes]

Hello John,

	if You are getting undefined references to gobject, try to 
export LDFLAGS=`pkg-config --libs gobject-2.0 gthread-2.0 gmodule-2.0`
before running configure. If it does not work try to send us some error
messages from the compiler but I am not sure if I can help since I have
not been compiling python bindings.

	By the way, were you able to compile and run gstreamer on Windows? I
had not time to work on the Windows port lately, is there anything that
should be added or changed in http://gstreamer.xeris.cz/winport.html ?

	Regards
		Michal
