gst-element-maker

[Carla Dias]

Hi,

I'm a new in gstreamer plugins. I'm following the GStreamer Plugin Writer's
Guide and using gstreamer 1.0.5. I saw the fix-me note on section '3.2.
Using the Project Stamp' recommending to use gst-element-maker insted
make_element. So when I used it I got the bellow errors:

Looking in gst-element-maker script code, I noted  some occurrence of the
-1 wrong argument to head -n command:

GST_TYPE_BASE_REPLACE=`grep -A 10000 '^% TYPE_CLASS_NAME'
$templatedir/$class | tail -n +2|grep -m 1 -B 10000 '^%'|head -n -1`

I changed the argument and even so I got the bellow errors:

What am I doing wrong? Seeing the logs look like it is necessary to install
gstreamer 0.10...

And if I use ../../gst-plugin/tools/make_element where do I found the
source files templates? In the template project there is only gsttransform
(.c .h).


Thanks,
Carla
