[Bullseye] RealVNC requires a rebuild against new libraspberrypi0 #267

Closed MichaIng closed 2 years ago

MichaIng commented 2 years ago

due to the changed shared object file names that got .0 suffixes.

spl237 commented 2 years ago

I can't repeat this - both the Server and Viewer work fine for me. RealVNC have tested themselves and also cannot find a problem. Can you provide any more detail as to what you are doing and what error you are actually seeing?

MichaIng commented 2 years ago

You did test it with the Bullseye suite of archive.raspberrypi.org and its libraspberrypi0?

The libraries moved from /opt/vc/lib to /usr/lib/arm-linux-gnueabihf, but more importantly they got a .0 suffix, which is why RealVNC dynamic links point to non-existing objects without this suffix. This way it has been aligned with the 64-bit libraspberrypi0, where this was the case for a long time.

XECDesign commented 2 years ago

@spl237 Are RealVNC aware of the issue? The latest build still seems to have the problem.

Not much we can do on our end other than notify them, so I think I'll have to close this one.

MichaIng commented 2 years ago

With libraspberrypi-dev, symlinks /usr/lib/arm-linux-gnueabihf/libxyz.so => /usr/lib/arm-linux-gnueabihf/libxyz.so.0 are provided, so that it works then (the reason why Simon wasn't able to replicate, I guess), but of course a development headers package shouldn't be required for executing a binary.

spl237 commented 2 years ago

Not sure I had previously informed RealVNC about this; I've just emailed them.
