Raspberry Pi Compile Error

[jhsong999]

Hello, I trying Connect ToF Camera with Raspberry pi. but error occurs during the compile && run stage.

I Connect ToF Camera and Download Clone "https://github.com/ArduCAM/Arducam_tof_camera" Next time, Install dependencies after reboot. Then next time, I tried to compile, but an error occurred. The error contents are as follows. ㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡ [30%] Building CXX object cpp/CMakeFiles/preview_depth.dir/preview_depth.cpp.o /home/pi/Arducam_tof_camera/example/cpp/preview_depth.cpp:2:28: fatal error: opencv2/core.hpp: No such file or directory

It was confirmed that the path of the opencv2 code was different, so I tried to fix it directly with the link, but I kept getting new errors.

It is not possible to determine exactly whether it is a problem with the opencv2 path or the /dev/video0 camera connection that follows.

I'd like to ask if you can suggest some solutions. Thank you!

Hello, Thank you very much for reaching out to me and letting me know about the issue you are facing while trying to connect a ToF camera with a Raspberry Pi. I am sorry to hear that you encountered an error during the compile and run stage. Judging from the compilation error report, it is an opencv path problem.Of course, you can check whether video0 exists through the following command

ls /dev/video0

It is recommended that you uninstall opencv and reinstall it. If it still cannot start smoothly, you can consider using raspberry pi imager to install the latest Raspberry Pi image, which is a system environment that can guarantee smooth operation.

Hello, Thank you for responding to my response. I'd like to ask you one more question before proceeding with the work. [(https://docs.arducam.com/Raspberry-Pi-Camera/Tof-camera/Getting-Started/)] I was referring to this link and working on it. Raspberry Pi used in this link is version 4. Can I test the same with Raspberry Pi 3 by any chance? Can Raspberry Pi 3 test the same camera? The Raspberry Pi version I'm using is "Raspberry Pi 3 Model B V1.2" Thank you!

[dennis-ard]

You're welcome! Yes, it is possible to test the TOF camera module with your Raspberry Pi 3 Model B V1.2.

Hello, I reinstalled opencv and compiled it again. However, a new error occurred.

It is presumed to be a compilation error related to CMake, but the exact cause has not been found so far. Can you look at the following error log and give me some advice? Thank you!

[dennis-ard]

Yes, I'm glad you're about to succeed, just pull the latest code from the repository and compile it.

[jhsong999]

I'm sorry, but I didn't quite understand the instructions to get the latest code and compile it.

The code currently being compiled by Raspberry Pi is from the last version of the repository.

Are you saying that the compilation will fail simply because the code is old?

Could you please post a link where I can download the last version of the code?

Excuse me while you're busy.

[dennis-ard]

I just updated the code of the repos,you can check whether the commit is 6d5be4219b0475798217286e73e17d917678a392.

[jhsong999]

Thank you! I got the code from the latest store and compiled it. However, a new error occurred again. New error code. ㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡ pi@raspberrypi:~/Downloads/Arducam_tof_camera $ ./compile.sh -- Configuring done -- Generating done -- Build files have been written to: /home/pi/Downloads/Arducam_tof_camera/example/build [ 20%] Built target test_c Scanning dependencies of target preview_depth [ 30%] Building CXX object cpp/CMakeFiles/preview_depth.dir/preview_depth.cpp.o /home/pi/Downloads/Arducam_tof_camera/example/cpp/preview_depth.cpp: In function ‘int main()’: /home/pi/Downloads/Arducam_tof_camera/example/cpp/preview_depth.cpp:121:13: error: ‘applyColorMap’ is not a member of ‘cv’ cv::applyColorMap(result_frame, result_frame, cv::COLORMAP_JET); ^~ /home/pi/Downloads/Arducam_tof_camera/example/cpp/preview_depth.cpp:121:59: error: ‘COLORMAP_JET’ is not a member of ‘cv’ cv::applyColorMap(result_frame, result_frame, cv::COLORMAP_JET); ^~ cpp/CMakeFiles/preview_depth.dir/build.make:62: recipe for target 'cpp/CMakeFiles/preview_depth.dir/preview_depth.cpp.o' failed make[2]: [cpp/CMakeFiles/preview_depth.dir/preview_depth.cpp.o] Error 1 CMakeFiles/Makefile2:146: recipe for target 'cpp/CMakeFiles/preview_depth.dir/all' failed make[1]: [cpp/CMakeFiles/preview_depth.dir/all] Error 2 Makefile:83: recipe for target 'all' failed make: *** [all] Error 2 Compilation error, please check whether /dev/video0 exists, or check whether the driver and sdk are installed successfully! ㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡ

An error appears to be outputting for the cv structure.

Can you give me some advice on the problem of the following error? Thank you always!

[jhsong999]

For additional information, the version of opencv you installed is 2.4.9.1.

Could it have anything to do with this?

[dennis-ard]

I checked the documentation of OpenCV 2.4.9 and found that it is there,so if it is normal, there should not be such a compilation error. I am sorry that this code I only tested on OpenCV 4.0+ version. Maybe you can try to upgrade the version of OpenCV, or just comment this statement. This The purpose of the segment statement is to map the grayscale values of the image to JET.

[jhsong999]

For Opencv, I installed it through Install_dependencies.sh in the repository, but in this case, should Opencv be upgraded separately?

And after investigating the code, it seems that there is no code file that has been declared with the structure related to the cv.

[dennis-ard]

Can you use unam -a to provide your system version, Install_dependencies.sh, this script only installs opencv through the following command, and generally installs OpenCV 4.5+ version in the system version of bullseye .

sudo apt update
sudo apt install libopencv-dev

You can manually search to see if there is a higher version of opencv and download opencv.

apt search libopencv-dev

The opencv library is in namespace cv.

If it is not possible to manually download a higher version of opencv, it is recommended that you flash the latest bullseye system to run the Arducam TOF camera.

[jhsong999]

This is the result of using the "uname -a" command.

Linux raspberrypi 4.19.66-v7+ #1253 SMP Thu Aug 15 11:49:46 BST 2019 armv7l GNU/Linux

And I downloaded OpenCv again using the command below.

sudo apt update sudo apt install libopencv-dev

But the same version was 2.4.9.1.

I also manually searched for higher versions, and the maximum version detected was 2.4.9.1. In this case, should I try to install it manually? Let's try to install version 4.0 or later of OpenCv.

[dennis-ard]

It looks like your Raspberry Pi version is buster, and the system version required for the camera to run is bullseye. Run lsb_release -a, you can view your codenam. It is recommended that you update your system to bullseye.

[jhsong999]

Results for lsb_release -a.

ㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡ No LSB modlues are available. Distributor ID: Raspbian Description: Raspbian GNU/Linux 9.13 (stretch) Release: 9.13 Codename: stretch ㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡ

I understood that Raspberry Pi's version is an "buster", so I need to update it to "bullseye", the camera operating environment.

Is my understanding correct?

If it's right, I'm going to upload it as bullseye on my new SD card.

[dennis-ard]

yep,that's right.

[jhsong999]

I updated Raspberry Pi os new and it was compiled normally!

Thank you so much for responding to so many requests!

[dennis-ard]

It is my pleasure to serve you!
