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

[Thomas Winkler]

Hi!

I've modified the gstplugin.c file for more output data (g_module_error()
inserted):

Here's the output with modified source:

root at triton1:/# GST_PLUGIN_SYSTEM_PATH=/usr/lib/gstreamer-0.10 gst-inspect
--gst-debug-level=4

And here's what "nm" says about:
vmgentoo
#/usr/local/arm/cross-gcc-4.2.0/i686-pc-linux-gnu/bin/arm-926ejs-linux-gnu-n
m libgstcoreindexers.so
<see attached file "nm.log">

Testing the library with "file"-command reports:
vmgentoo #file
/usr/local/arm/cross-gcc-4.2.0/i686-pc-linux-gnu/arm-926ejs-linux-gnu/sys-ro
ot/usr/lib/gstreamer-0.10/libgstcoreelements.so

/usr/local/arm/cross-gcc-4.2.0/i686-pc-linux-gnu/arm-926ejs-linux-gnu/sys-ro
ot/usr/lib/gstreamer-0.10/libgstcoreelements.so: ELF 32-bit LSB shared
object, ARM, version 1, not stripped

Could it be a problem with the first underscore of _gst_plugin_desc because
in the table there's just an export without underscore (gst_plugin_desc)
(Compare log-file with debug output)


Any ideas what's going wrong?

Best regards,
Thomas
