i am working on Project using Raspberry pi and pi camera board.
and i want to install opencv based on C language.
What is the command about installing OpenCV based on C language on Raspberry pi Board ?
Thanks for your help.
Try this:
sudo apt-get install libopencv-dev python-opencv
And go check this page.

I'm having a bit of trouble installing python dronekit on my raspberry pi 4B (8GB) (bullseye).
I know that dronekit does not support Python3, hence I am running a virtual python environement (dronekitty)
I'm new to Linux and beginner at c programming. I'm trying to install eclipse on Linux Ubuntu. I have installed openjdk-16-jdk and downloaded eclipse-cpp-kepler-SR2-linux-gtk-x86_64. When i try to open eclipse by double clicking on eclipse icon i get this message in the image
how can i get eclipse to run on Ubuntu ?
Try to start Eclipse from the console:
home/eclipsePath/eclipse -clean
So I've compiled my C code in xcode and it works fine, it compiles. Now I want to plot the output data of said compiled program. What's the best way to do this, or what program should one use to plot data on a mac? If I use ubuntu, I would compile in emacs and use gnuplot, but that doesn't seem to be an option on mac.
If you install homebrew, gnuplot is available on OS X.
You can install it by running the following in your terminal:
brew install gnuplot
I have to design a C executable (no GUI) that is supposed to run on Raspberry PI. I'm familiar with design using IDE like Visual Studio or Eclipse (with CDT plugin). If i use Raspberry PI as a design machine, I think I have no chance to use a standard IDE. I should use makefiles and gcc compiler only.
Is there any chance to develop Raspberry PI executable using Visual Studio (for Windows) or Eclipse (for both Windows and Linux).
You can specify to eclipse projects with Makefiles. You can also specify a compilation toolchain.
So yes, you can develop and compile for Raspberry Pi or for other plateforms using Eclipse.
For getting toolchain and other tools for Rasp Pi you can find things here.
In Eclipse, you create a new or import a project choosing Makefile Project with Existing Code then add your toolchain.
If you have a newer Pi like the 4, you should be able to run eclipse directly from the Pi desktop. You can download via:
sudo apt-get install eclipse
This will be a stripped-down version and will likely run quite slow, so I agree compiling on a more powerful remote machine is better...

Yes, this is called cross-compiling. You can set up a cross-compile toolchain for the raspberry pi on windows or linux and configure your Eclipse CDT project to build with the toolchain. You can even set up remote debugging.
This website has good information and a step-by-step guide for windows using cygwin.
This looks like a good guide for linux.
Edit:
Just realized you asked for Visual Studio on Windows. I don't think there is Visual Studio support for this. The example I pointed to sets up cygwin so you have an emulated linux environment. You could also set up a VM using free VM software and install a linux environment that way, and run eclipse CDT from there. This is what I did when setting up a cross compiling environment for the Raspi.
I have a simple Arduino sketch that spans several files. There is a function signature in an h file, and the definition in the C file.
If I attempt to compile ("Verify") the sketch, I get "undefined reference" errors to the function defined in a C file. Changing the file name from *.c to *.cpp resolves the issue, but I don't want to define the file as a C++ file. Is it possible to compile plain old C files in Arduino?
The Arduino IDE is very limited, my advice: avoid it. You have some alternatives you can find here: http://arduino.cc/playground/Main/DevelopmentTools
