I need to use the Raspberry Pi camera with OpenCV. For that, I have to run sudo modprobe bcm2835-v4l. But for that, I need to install it. I did it on another RPi a while ago, but I forgot the whole procedure.

I'm now following a post from here but I got a problem installing libjpeg62-dev :

The following packages have unmet dependencies:
 libjpeg62-dev : Depends: libjpeg62 (= 1:6b2-2)

Then I followed that post and I added deb [trusted=yes] http://mirrordirector.raspbian.org/raspbian/ wheezy main contrib non-free rpi to /etc/apt/sources.list (I should specify [trusted=yes] otherwise the protection prevented me to use that repository). But even after the update, I was not able to install the package (same error).

I also tried to installed libjpeg62 (without dev) myself but it said it will remove 140 (!) packages, which looks important, so I aborted it.

The following packages will be REMOVED:

Finally, I checked with aptitude, and got that answer:

The following packages have unmet dependencies:
 libjpeg62-turbo : Conflicts: libjpeg62 but 1:6b2-2 is to be installed
The following actions will resolve these dependencies:

     Keep the following packages at their current version:
1)     libjpeg62 [Not Installed]
2)     libjpeg62-dev [Not Installed]

So, it looks like there is a conflict with libjpeg62-turbo, I checked to uninstall it, but again it will remove many packages, hence I aborted it again.

So, now I am a bit lost and I don't know what to do. What should I do to install that package?

Thanks in advance

  • are you really using wheezy? May 24, 2021 at 6:25
  • I followed one post that said the package libjpeg62-dev had been removed from the current release and I should use an old one. But I am not familiar with that, so I understood it's not really good, and I planed to remove wheezy when I manage to install my package. May 24, 2021 at 6:30
  • well, following an 8 year old guide is probably not helping - have you tried installing libjpeg62-turbo-dev? May 24, 2021 at 6:38
  • or maybe modprobe bcm2835-v4l2 May 24, 2021 at 6:42
  • having said that bcm2835-v4l2 seems to be loaded at boot anyway May 24, 2021 at 6:47

As it was proposed in a comment, I installed libjpeg62-turbo-dev, and also I activated the camera in raspi-config and now it works.
