Can't build on raspberry pi 3

[dirtdigger]

Hello, I'm trying to compile on a freshly updated rpi 3 but I'm running into problems. Here are the commands I've run:

git clone https://github.com/mpromonet/v4l2rtspserver.git
cd v4l2rtspserver
cmake .

So far so good, checks out v4l2wrapper and a couple of other things. I get a message saying that build files have been written. So I run

make

and then I get a bunch of errors:

Any advice? Thanks!

I have the same issue on a raspberry pi 4B 8GB. Any help is appreciated, thanks!

Hi,

Looking to http://www.live555.com/liveMedia/public/changelog.txt it seems live555 is implementing ipv6. This may have some impact in the code. The problem you mentioned seems fixed on release 2020.11.27, but modification in RTSPClientConnection interface need modifciation.

You may try using an older release that you can find for instance https://download.videolan.org/pub/contrib/live555/ running cmake with -D LIVE555URL=https://download.videolan.org/pub/contrib/live555/....

Best Regards, Michel.

Thanks for the quick response Michel!

I cloned the v0.2.1 and ran the cmake with cmake -D LIVE555URL=https://download.videolan.org/pub/contrib/live555/live.2020.08.19.tar.gz

Working perfectly now!

Awesome, thank you! I figured it was probably a live555 issue, but I couldn't find an older version on their website.
