OpenCV 4.5.2 error at 95%. Is this considered an issue? #1

Closed DWSuryo closed 3 years ago

I encountered issue at 95% when running the .sh file for 4.5.2 version. Here's the issue I got: Note opencv install (250621).txt

is this normal?

Dear @DWSuryo,

In file included from /home/lunar/opencv_contrib/modules/tracking/src/gtrTracker.hpp:47:0,
                 from /home/lunar/opencv_contrib/modules/tracking/src/gtrTracker.cpp:42:
/home/lunar/opencv/modules/video/include/opencv2/video/tracking.hpp:713:20: error: redefinition of ‘class cv::Tracker’
 class CV_EXPORTS_W Tracker

This behavior is not normal. It hints at two files declaring the same variable differently. The question is now, how does you end up with these two files? I see that one is located at /home/lunar/opencv and the other in /home/lunar/opencv_contrib. I think you have somehow different versions of opencv and opencv_contrib. Please make sure they are both of the same relaese. I've modified the script file a bit. Now all opencv directories will removed before a new build is initiated. Hopefully, it will prevent version mismatches.

I'm back. So I deleted manually opencv related folders, then i used your latest shell file. Here's the terminal message: OpenCV 452 error2.txt

Looks like i had trouble while doing cmake commands. Here's the file: CMakeError.log CMakeOutput.log I think this one is not normal. Are there solutions?

Dear @DWSuryo,

I'm not sure how you done it, but your system is serious corrupted.

Looking at your OpenCV 452 error2.txt, you can see it tries to load '/usr/lib/x86_64-linux-gnu/libgtk3-nocsd.so.0', which is normally found on a PC running a x86_64 core, not the ARM core found on the Jetson Nano.

The script installs libgtk-3-dev. However, it should be the ARM version, located at /usr/lib/aarch64-linux-gnu. Simply deleting the '/usr/lib/x86_64-linux-gnu/ folder will not do. You have all kinds of references to the location, which will crash you system as soon as you call them.

Personally, I would flash a new and clean SD card with the latest Jetpack and install this fresh version.

Sorry late reply, I've flashed the image. Now I've done it properly. Thank you for updated instructions
