Trying to build v2.0.8 on Raspi with Debian Buster, getting errors

[HWiese1980]

I'm trying to build picam v2.0.8 on a Raspberry Pi running Debian Buster. I'm getting the following error messages upon make:

Can anyone tell me what's causing these?

Thank you!

Did you install ffmpeg as described in the build instructions? https://github.com/iizukanao/picam/blob/master/BUILDING.md#build-and-install-ffmpeg

If you installed ffmpeg with apt or apt-get, please uninstall it first.

Apparently not. I did not even notice the BUILDING.md. Thanks for the link. I'll see if that helps.

Sad news, I've decided to mothball the project of a self-built surveillance camera for now, and purchased a cheap IP camera instead. All this tinkering to make it work was too much for my wife who just wanted a reliably working camera. So I'll probably not be able to pursue this topic further any time soon - not, unless I'll find another project that needs a dedicated IP camera.

I'm really sorry. I'll close this topic for now... if anyone else runs into the same issue, feel free to open it up again and add all the info that you have. Thanks!
