Configuring opencv

English Applications

In openSUSE I can install openCV with zypper:

 sudo zypper install opencv

But it doesn’t work:

         ^

martin@linux-vb3j:~/Documents/C>

The problem is that I can’t actually find it as well:


martin@linux-vb3j:~/Documents/C> whereis opencv 
opencv: 
martin@linux-vb3j:~/Documents/C> opencv 
If 'opencv' is not a typo you can use command-not-found to lookup the package that contains i
t, like this: 
   cnf opencv 
martin@linux-vb3j:~/Documents/C> type opencv 
bash: type: opencv: not found 
martin@linux-vb3j:~/Documents/C> man opencv 
No manual entry for opencv 
martin@linux-vb3j:~/Documents/C> zypper install opencv 
Root privileges are required for installing or uninstalling packages.
martin@linux-vb3j:~/Documents/C> sudo zypper install opencv 
[sudo] password for root:

Reading installed packages... 
'opencv' is already installed. 
No update candidate for 'opencv-3.1.0-3.25.x86_64'. The highest available version is already

Nothing to do.

Been awhile since I’ve done anything with opencv,
IIRC it’s just a collection of libraries, there aren’t any applications.

So,
I don’t know what you’re trying to do with the commands you’re running, are you following some kind of reference (post a link if you are) or installing it as a prerequisite for an application (post a link to that as well if you are).

As to where your files are located, and probably how your files are accessed (my guess is that a PATH should already point to your files), you can run the following

rpm -ql opencv

Or, you can use the “find” or “locate” utilities (the latter is installable as part of the mlocate package).

Ok, now I have to build it ? or add it to some path ?
