Hello,
I have successfully installed Jetpack 4.2 using the sdk on my jetson tx2. I was building the opecv 3.4 but it always stops at 47% giving the error as :
No rule to make target ‘/usr/lib/aarch64-linux-gnu/libGL.so’, needed by ‘lib/libopencv_cudev.so.3.4.1’. Stop. tx2
Can some one please help me solve this problem or help me build opecv 4.0
Thanks
sandeepkumarjangir0,
Did you see this libGL.so under that path?
Yes,the file exist under that path .!!
Please try to use these script.
Hi sandeepkumarjangir07,
As WayneWWW proposed, I followed the link to the openCV installation files and have been able to install OpenCV 4.0.0 with the “install_opencv4.0.0_Nano.sh” on my Jetson TX2 by changing the architecture to 6.2. I had some issues with packages that were not too hard to fix so you should be able to do the same and have OpenCV 4.0.0 running on your TX2.
Bye :)
Thank you all for the reply. I re-flashed my TX2 with jetpack 4.2 and built the opencv 4 using the nano script. But my python 2 and 3 version of opencv has been downgraded from 3.3.0 to 3.2.0 instead upgrading it to 4.0. The binding for python in the script are ON but still couldn’t figure out how to update my opencv version of python 2 and 3 to 4.0. There were no errors during the build(some warning of course but nothing serious ). can you guys suggest something that might be wrong or something that could be done to make my python-opencv version to 4.0 ?
Hi Sandeep,
If I remember correctly, to install latest opencv-python, you should not use apt-get or any tools that can directly download the prebuilt library.
You will need to build it from opencv source by yourself. I think opencv forum or some external links should have such tutorial.
you are right WayneWWW but I am building the opencv from the source.
When I build opencv 3.4.0, I get the error No rule to make target ‘/usr/lib/aarch64-linux-gnu/libGL.so’, needed by ‘lib/libopencv_cudev.so.3.4.1’. Stop. tx2 and when i checked the libGL.so, the link is broken and there should be another libGL.so present in /usr/lib/aarch64-linux-gnu/tegra directory but its not there.
Then I started building the opencv 4.0, which does build properly without any errors but my python version shows the opencv version as 3.2.0.
I am trying to solve errors from either of the build but nothing is proving to be working. I have flashed my jetson once and do not want to do it again because flashing takes a lot of time and also building tensorflow and protobuf from source takes even more (not even including the opencv build :-p)
if you can help me with libGL.so file or give me a reason why build of opencv4.0 still shows version 3.2.0 that would be helpful.
regards

Do you mean the default jetpack has a empty symlink for libGL.so? I will help check.
I don’t think opencv4.0 gives the 3.2 opencv-python. Are you sure you didn’t install it by using apt-get or something else?
Yes, there was no libGL.so so i re-flashed tx2 with 4.2 again and its present now. But instead of building Opencv 3.4.0 , i tried again to install opecv 4.0 and below is the log after the build and opencv version that it shows.

I’m working on multi-class object detection with tracking on Jetson Nano.
I’d like to use the tracking libraries in opencv.
I successfully installed opencv using WayneWWW’s script:
[url]https://github.com/AastaNV/JEP/tree/master/script[/url]
However no trackers (ex: cv2.TrackerMOSSE_create) were installed.
Could someone kindly help me install opencv’s object trackers or suggest a replacement object tracker for the Jetson Nano?
Hi silasv38em,
Please file your issue into Jetson Nano forum: https://devtalk.nvidia.com/default/board/371/jetson-nano/
hello , i am trying to install opencv and opencv-contrib as i wanted to use the “xfeatures2d” from the contrib/modules but when i try to compile the opencv by using the command “make -j4” after 34% it stops and the jetson runs out of memory. I have 5 GB of free space in the jetson tx2 .
can anyone help me out ?
Thank you.
I cannot tell you what is the necessary disk size for installing opencv, but sometimes the makefile will create too much file simultaneously when you compile with -j option. You could try to use -j2 with slower build time or just some external storage(usb/sdcard).
Do i have to flash jetpack 4.2 if i want to install opencv 4.0?
