Re: [Linphone-developers] crosscompiling with modern tools possible?

[Nicolas Michon]

Hello,


I didn't really understand what you are trying to achieve here. Building 
linphone-desktop (Qt client) or linphone-sdk with your own client on top ?

We actually never tried compiling with VS2019 (If it doesn't work now, 
it will before the next desktop release) nor cross-compiling from windows.

Cross-compilation can be tricky enough without Windows in the equation 
and I won't try it. Some have tried with the linux subsystem for Windows 
but IMO it should be easier with a linux virtual machine or directly on 
the raspberry. Yocto is also an alternative to build for the raspberry.

You can find documentation about linphone on raspberry here: 
https://wiki.linphone.org/xwiki/wiki/public/view/Linphone/Linphone%20and%20Raspberry%20Pi/#HCompilinglinphoneontherasberrypi 
(remove the 'no-ui' part in the configure script to include QT interface).

Not for now, but some work has been done to make the python wrapper work 
with python3. You can try with the following git branch of the linphone 
project:
