[gst-devel] gst-inspect cannot find any Plugins

[Thomas Winkler]

Hi all,

I've resolved this problem, I'm very happy now.
My mistake was to configure glib2 wrong.
I have defined a wrong config-cache file
Inside this config-file I've defined
glib_cv_uscore=yes
but my architecture needs to be configured with
glib_cv_uscore=no

Now, gst-inspect is able to find the symbols.

Thanks to all!

Best regards,
Thomas
