Building rpicam-apps without building libcamera on Pi 4B + ubuntu 22.04

[Jai-GAY]

I am just curious, does anyone build the rpicam-apps without building the libcamera successfully on Ubuntu 22.04 64bit?

Did you install libcamera-dev via apt?

This sounds like Canonical may have something wrong with their libcamera-dev package. Probably something to do with the pkg-config file which is used to locate the libcamera library. I'm afraid you will have to get in touch with their support to resolve this.

This sounds like it needs to be fixed by the Canonical team. libcamera.pc is needed to locate the libcamera library needed by rpicam-apps. I'm afraid there's nothing more I can do to help here, but I'm sure the Canonical support team will be able to help.

We only officially support Raspberry Pi OS.
