[gst-devel] Illegal instructions

[Daniel Díaz]

Hello, there!

I'm getting some "Illegal instruction" messages with some specific
plugins, namely libgstaudioresample.so, libgstvideotestsrc.so, and
libgstvideobox.so.

Whenever those are in /lib/gstreamer-0.10/, gst-inspect will break.
Here's the final part of the log with debug-level=5:

-----8<----------8<----------8<----------8<----------8<-----

"/lib/gstreamer-0.10/libgstaudioresample.so" looks good
Illegal instruction
#
----->8---------->8---------->8---------->8---------->8-----

The file looks good at first sight, no cross-compilation mistake:
$ file libgstaudioresample.so
libgstaudioresample.so: ELF 32-bit LSB shared object, ARM, version 1
(ARM), not stripped
$ file libgstvolume.so
libgstvolume.so: ELF 32-bit LSB shared object, ARM, version 1 (ARM),
not stripped

The versions for this compilation would be:
gstreamer-0.10.4
gst-plugins-base-0.10.5
gst-plugins-good-0.10.2
gst-plugins-bad-0.10.1
gst-plugins-ugly-0.10.2
liboil-0.3.8

I know there were some issues with a certain version of liboil and
ARM, but I think those were fixed by 0.3.7.

Would this information ring any bell on anyone? There must be
something in common between those 3 plugins (audioresample,
videotestsrc, and videobox) that is making and "illegal instruction"
whenever those are in the plugins path.

Thanks for any pointers. Greetings!
