[gst-devel] Small build patch

[Richard Boulton]

Hi list.

Been a while since I've checked out Gstreamer - I'm still to busy with 
work to be much use, sadly.

I just tried a test build (from current CVS HEAD) though, and found a 
couple of problems - I have a patch for one of them. :\

Firstly, in the gstreamer module, gst/parse/Makefile.am defines a rule:

lex._gst_parse_yy.c: parse.l
        $(FLEX_PATH) -P_gst_parse_yy $^

This causes a VPATH build to fail with "can't find parse.l".
The fix is to copy a trick from the internals of automake - the fix is
(I also converted $^ to $< - $^ is GNU make specific, or at least 
non-POSIX make, whereas $< isn't):

  lex._gst_parse_yy.c: parse.l
-       $(FLEX_PATH) -P_gst_parse_yy $^
+       $(FLEX_PATH) -P_gst_parse_yy `test -f '$<' || echo '$(srcdir)/'`$<


Also, when building gst-plugins/gst-libs/ext/ffmpeg/ffmpeg/libavcodec, I 
get the following error.  My system is Debian unstable, running on an 
AMD Athlon 1200 MHz processor. I have no experience of this stuff, so I 
just disabled ffmpeg for now.  Hope this helps.
