Building on jetson orin nx deepstream 6.4 ubuntu 22

[erencerman]

Hi. I cannot install pylonsrc gst for Jetson Nx on Ubuntu 22 with Deepstream 6.4.

I have tried with pylon 7.4 and 7.3, both fails.

I have build system on SDK manager. DS 6.4 test samples work. Pylon camera works too. A Pylonsrc camera requires meson ninja as…:

.What could be the reason?

[thiesmoeller]

Error from testcode picking up the python extension during test.

Current code is not linking directly to python and expects that it gets loaded by python interpreter.

You can ignore the error for now. We need to check why gstreamer on JP 64 is loading the extension during test

[erencerman]

I just need the simple pylon gst to run Deepstream 6.4.

[thiesmoeller]

You call ninja -C builddir test

This executed the test, which cause an error in the b test.

Just call ninja -C builddir install

[erencerman]

Thanks for the help. Test is not the issue, I make ninja -C builddir install and apperently it seems to install without error, yet then, gst does not recognize pylon as a plug-in. gst-inspect-1.0 pylonsrc does not find it as installed...

[erencerman]

Maybe it builds "libgstpylon.so" and I have to define the LDpath or symlink?

[thiesmoeller]

no this shouldn't be required.

Could you please show the output of:

gst-inspect-1.0 fakesink | grep Filename

This will list the standard install directory of gstreamer plugins.

And list the output of

gst-inspect-1.0 -b

this will show if pylon plugin got blacklisted somehow.

and show the output of

ninja -C builddir install -v

This will show if somehow the plugin gets installed in the wrong place

[erencerman]

pylongst-log.txt Hi. Thanks. It seems to be blacklisted. The log is attached.

rm ~/.cache/gstreamer-1.0/registry.aarch64.bin

was not successful.. What would you suggest, how can I rescan or unblacklist? Is it because of

"0:00:00.033725172 6358 0xaaaae5951e00 INFO GST_INIT gst.c:833:init_post: GLib runtime version: 2.72.4 0:00:00.033738521 6358 0xaaaae5951e00 INFO GST_INIT gst.c:835:init_post: GLib headers version: 2.72.1" ?

[thiesmoeller]

You un+blacklist by deleting the registry from your log I can see that the rpath is not correctly set.

What is the meson version you use ?

We are using a feature of meson that was on deprecation list...

You can downgrade to e.g. meson. 1.0 by

pip install meson==1.0.0

[erencerman]

pip install meson==1.0.0 is not helpful either. Log : pylon-setup_log2.txt Any more suggestions?

Thanks a lot..

We can reproduce your issues now and are checking what in the combination of latest Ubuntu on latest jetpack triggers this regression

@thiesmoeller Any updates?
