Unable to use plugin after build and install

[kfechter]

I built and installed the plugin following the directions, however trying any of the commands results in the error

No such element or plugin 'icamerasrc'

I've tried rebuilding it and reinstalling it to no avail. gst-inspect-1.0 doesn't show the plugin as installed.

I am installing this on a tigerlake system with IPU6, the drivers, hal, and bins are all installed, as well as ll prerequisites for this repo.

Do you see icamerasrc being blacklisted (gst-inspect-1.0 -b)?

Have you tried to delete the "plugin registry" (under /.cache/gstreamer-1.0/registry*.bin)?

And then, check again with GST_DEBUG=4 gst-inspect-1.0 icamerasrc whether there are any icamerasrc related log messages.

Where can you see your built icamerasrc shared library?

From "https://github.com/intel/icamerasrc/tree/icamerasrc_slim_api#pipeline-examples":

• Ensure ${GST_PLUGIN_PATH} includes icamerasrc installation path

Do you see the path being part of GST_PLUGIN_PATH, or can you add it?

[kfechter]

gst-inspect-1.0 -b shows no blacklisted modules removing the cache does not change anything the library is installed in /usr/lib/x86_64-linux-gnu/gstreamer-1.0/ with the other plugins that are being loaded

there is a warning loading the plugin in the debug output saying libia_cca.so can't be loaded but the file does exist in /usr/lib from the installation of one of the other requirements for ipu6.

[brmarkus]

In your environment with your given search-paths being set, can you call ldd to check if all dynamic-libraries are present?

$> ldd /usr/lib/x86_64-linux-gnu/gstreamer-1.0/libgsticamerasrc.so

What does gst-inspect-1.0 /usr/lib/x86_64-linux-gnu/gstreamer-1.0/libgsticamerasrc.so print (with/without gst-debug log level)?

[kfechter]

ldd shows three files missing, but doing an ls in the /usr/lib directory shows those files as being there. however, attempting to copy them results in an error saying the files don't exist for some reason

libia_cca.so => not found libia_log.so => not found libgcss.so.0 => not found

I was able to get those files re-copied, and now the icamerasrc plugin loads, but I have a new issue now.

Hello, I have the same problem that the plugin icamersrc cannot be loaded. I installed the libraries through the following AUR packages on archlinux 6.1.18-1-lts:

• icamerasrc-git
• intel-ipu6-dkms-git
• intel-ipu6ep-camera-bin
• intel-ipu6ep-camera-hal-git
• intel-ivsc-firmware

What I found out so far:

• gst-inspect-1.0 -b shows that libgsticamerasrc.so is blacklisted
• gst-inspect-1.0 /usr/lib/gstreamer-1.0/libgsticamerasrc.so outputs Failed to load plugin '/usr/lib/gstreamer-1.0/libgsticamerasrc.so': /usr/lib/gstreamer-1.0/libgsticamerasrc.so: undefined symbol: vied_nci_mem_type
• nm --defined-only --print-file-name $(find /usr/ -type f -iname "*.a") 2> /dev/null | grep vied_nci_mem_type outputs /usr/lib/libipu6ep.a:vied_nci_psys_resource_model.c.o:00000000000001b0 R vied_nci_mem_type

So it seems that the library /usr/lib/libipu6ep.a containing the symbol vied_nci_mem_type is present, but the icamerasrc still fails to load.

Does anyone have an idea why this is possible?

[brmarkus]

Not sure it's a runtime dependency (resolved at runtime via dlopen(), dlsym()) or a build-time dependency.

When calling ldd /usr/lib/gstreamer-1.0/libgsticamerasrc.so do you see all dependencies/libraries being resolved?

"/usr/lib/libipu6ep.a" is a static library/archive, not a shared library...

Do you see more when calling DL_DEBUG=libs gst-inspect-1.0 /usr/lib/gstreamer-1.0/libgsticamerasrc.so, i.e. which library tries to resolve the symbol with the help of which other libraries?

EDIT: I forgot to mention, that I could not perform the rpm steps:

# build rpm package and then install
make rpm
rpm -ivh --force --nodeps icamerasrc-*.rpm

Are these also important or just an alternative to the sudo make install before?

[brmarkus]

I'm not so familiar with "archlinux" and your mentioned "AUR packages"; make rpm creates the RPM packages which then will be installed via rpm -ivh --force --nodeps icamerasrc-*.rpm.

Could be related with your issue... i.e. a missing package not being installed - but is there really more than one (1) "icamerasrc" RPM file - as a wild-card is used in icamerasrc-*.rpm...?

In addition to "ldd" and "DL_DEBUG", do you see something different when calling strace gst-inspect-1.0 /usr/lib/gstreamer-1.0/libgsticamerasrc.so?

Where you required to rebuild the system library cache after building and installing icamerasrc (e.g. via ldconfig)?

I don't know, it fails to build with: cp: the call to stat for '' is not possible: file or directory not found

In addition to "ldd" and "DL_DEBUG", do you see something different when calling strace gst-inspect-1.0 /usr/lib/gstreamer-1.0/libgsticamerasrc.so?

There is a lot. Do you want me to paste everything in here?

Where you required to rebuild the system library cache after building and installing icamerasrc (e.g. via ldconfig)?

No I wasn't.

EDIT: After sudo make install (I removed all AUR packages and tried it manually according to the 4 steps on the github page) I got among other things:

Libraries have been installed in:
   /usr/lib

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the '-LLIBDIR'

     during execution
   - add LIBDIR to the 'LD_RUN_PATH' environment variable
     during linking
   - use the '-Wl,-rpath -Wl,LIBDIR' linker flag
   - have your system administrator add LIBDIR to '/etc/ld.so.conf'

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.

A note on the build_rpm.sh script in the rpm folder: The line rpm_path=$(awk '/^Wrote:.*rpm$/ { print $2; exit }' "$tempdir/rpmbuild.log") does not work if the bash uses other locales than englisch because of 'Wrote'.

The rpm is also found with this line instead: rpm_path=$(awk '/rpm$/ { print $2; exit }' "$tempdir/rpmbuild.log")

EDIT: The icamerasrc plugin is still blacklisted. I tried all of this on a Thinkpad X1 Carbon Gen10 with ov2740 sensor.

I had the similar issue to this comment https://github.com/intel/icamerasrc/issues/28#issuecomment-1411205262, then I realized that during some process, /usr/lib/libia_cca.so and other files copied from ipu6-camera-bins/<IPU_VER>/lib/ are turned into symbolic links.

I fixed this issue by simply doing:

mkdir /usr/lib/<IPU_VER>/
cp -r ipu6-camera-bins/<IPU_VER>/lib/* /usr/lib/<IPU_VER>/

[almereyda]

I can confirm that re-running the steps provided in:

• https://github.com/intel/ipu6-camera-bins/tree/main#deployment

will help GStreamer in finding an otherwise missing libgcss.so, symlinked at libgcss.so.0, which is then symlinked to libgcss.so.0.0.0, where the actual file will be found afterwards.

---

Edit: It appears the target locations of the symlinks are expected and prepared in step three of the HAL installation readme, "Move user space driver". To make it work (again) after all those mv commands, I had to issue cp /usr/lib/ipu6ep/libgcss.so.0 /usr/lib/ to have GST_DEBUG=4 gst-inspect-1.0 -b report positively again.

Also moving the camera directory into the ipu6ep directory is not expected by all other components, why a heartful cp -r /usr/share/defaults/etc/ipu6ep/camera /usr/share/defaults/etc helped to get it back in place, where it would be expected.
