Error compiling for Ubuntu #55

Closed mkaivs closed 3 years ago

mkaivs commented 3 years ago

I only need the pylonsrc plugin, I've installed pylon 6 (include path /opt/pylon/include, lib path /opt/pylon/lib) so I modified FindPylon.cmake accordingly to work with pylon 6 instead of pylon 5 as follow:

Line 15: set (_PYLON_DIR "/opt/pylon5") -> set (_PYLON_DIR "/opt/pylon") Line 32: "${PYLON_DIR}/lib64") -> "${PYLON_DIR}/lib")

Then, I followed the instruction to compile for Ubuntu. Running cmake ..:

No error, but 2 warnings about: Target "gstgentl" requests linking to directory "/usr/include/gstreamer-1.0", I think this is probably cause by this line ${GSTREAMER_INCLUDE_DIR}/../../lib/z.lib?

I looked at the CMakeLists.txt for gentl and on line 25, I saw this: ${GSTREAMER_INCLUDE_DIR}/../../lib/z.lib, I'm not sure what is this library (z.lib) that I'm missing? How do I deal with this error?

mkaivs commented 3 years ago

Ok, my assumption was that gentl is not a dependency of pylonsrc so I can skip building it. Thus, I comment out line 17 of this CMakeLists.txt file to skip building gentl all together. Then I had to modified line 131 of this CMakeLists.txt file from set(_PREFIX "/usr/lib") to set(_PREFIX "/usr/lib/x86_64-linux-gnu"), I tried export CMAKE_INSTALL_PREFIX=/usr/lib/x86_64-linux-gnu but it failed to overwrite the default value of CMAKE_INSTALL_PREFIX so I must hard code the path in the CMakeLists.txt file. With these 2 changes, the following run without error:

cmake ...
make
sudo make install

However, when I double check with gst-inspect-1.0 pylonsrc, it said the plugin was not found and a warning about libpylonc-6.2.0.so not found. Do a quick check:

ldd /usr/lib/x86_64-linux-gnu/gstreamer-1.0/libgstpylon.so

/lib64/ld-linux-x86-64.so.2 (0x00007fd607590000)

Now to fix this, I add pylon.conf to /etc/ld.so.conf.d dir, the file contain the pylon 6 lib path /opt/pylon/lib

sudo vi /etc/ld.so.conf.d/pylon.conf 
#add /opt/pylon/lib to the file
sudo ldconfig

Now, gst-inspect-1.0 pylonsrc works, but it gave this warning:

** (gst-inspect-1.0:29954): WARNING **: 10:32:12.120: /home/minh/gst-plugins-vision/sys/pylon/gstpylonsrc.c:1447: invalid property id 30 for "coloradjustment" of type 'GParamBoolean' in 'GstPylonSrc'
flags: readable, writable

Is this something I need to worry about? How do I get rid of this warning?

mrstecklo commented 3 years ago

@mkaivs, invalid property id means that property is installed on plugin, but there is no handler for it in set_property() and get_property() functions. It is an uncritical error, that should be fixed.

Then I had to modified line 131 of this CMakeLists.txt file from set(_PREFIX "/usr/lib") to set(_PREFIX "/usr/lib/x86_64-linux-gnu")

I'm not really sure, but shouldn't you use cmake --prefix=/usr/lib/x86_64-linux-gnu ..?

libpylonc-6.2.0.so => not found

That's a common problem as far as I know. I'm using LD_LIBRARY_PATH

mkaivs commented 3 years ago

@mrstecklo

I'm not really sure, but shouldn't you use cmake --prefix=/usr/lib/x86_64-linux-gnu ..?

You're correct. I'm new to CMake so I wasn't aware that I can just set CMAKE_INSTALL_PREFIX directly as cmake -DCMAKE_INSTALL_PREFIX=/usr/lib/x86_64-linux-gnu ..

It is an uncritical error, that should be fixed.

Thanks for the clarification. Is this something that will be addressed in the next release?

mrstecklo commented 3 years ago

Thanks for the clarification. Is this something that will be addressed in the next release?

Yes, I'll fix it shortly

init-22 commented 3 years ago

@mrstecklo @mkaivs I've followed the steps mentioned above and exported the /opt/pylon/lib in LD_LIBRARY_PATH but I am still getting 'No such element or plugin 'pylonsrc' ' , I've also commented out line no. 17 in src/cmaklists

Please find the steps I've taken for make and cmake :

@init-22, your output seems fine. Please clear gstreamer plugin cache and run gst-inspect-1.0. This should provide a more verbose output on error

rm ~/.cache/gstreamer-1.0/*

Since gst-inspect-1.0 can't say anything specific about pylonsrc I would suppose that libgstpylon.so is not installed or broken. Does ls /usr/lib/x86_64-linux-gnu/gstreamer-1.0/libgstpylon.so print back anything? Try setting GST_PLUGIN_PATH to your build directory

After this I think that many .so files are not generated like libgsttimecode.so, libgstaudiotestsrc.so etc.

mrstecklo commented 3 years ago

Did you install GStreamer with package manager or built from source? Maybe you should reinstall GStreamer and then try to rebuild plugins. You can also try running gst-inspect-1.0 -b to see if it lists libgstpylon.so

mrstecklo commented 3 years ago

Your shell prompt looks a bit confusing.

(base) ➜ build git:(master) ✗

I mean those non-ASCII symbols. If that is not what you actually see in terminal you can enclose shell output in grave-accent signs (ctrl+e)

init-22 commented 3 years ago

@mrstecklo thanks a lot for your guidance, I had also installed gstreamer in one conda env, I thought of giving it a try after you asked me reinstall and it worked. Thanks. BTW, the shell prompt looks confusing here but it looks fine in my terminal though.
