Re: [Linphone-developers] running the tutorials

[Simon MORLAT]

Hi Cameron,

The errors at startup relate to the fact that:

- no camera could be detected

- no soundcard could be detected

- DSCP tagging of RTP packet doesn't work (maybe due to insufficient permissions ?) - anyway this is not required to operate

Maybe you are doing your test in a virtual machine without sound device or camera configured ?

Anyway these errors are unrelated to the failure of the call, which is probably because your server requires an authentication with password, but the tutorial doesn't allow this (it is a very simple example).

I suggest that you modifiy the tutorial source code by using linphone_core_create_auth_info() and linphone_core_add_auth_info() to setup a password from command line.

Finally, regarding compilation of the project on windows, the easiest way is to clone the linphone-desktop project, because it includes most dependencies as git submodules.

git clone git://git.linphone.org/linphone-destkop --recursive

git checkout 4.1.1

git submodule update --init --recursive

4.1.1 is the last stable tag, but HEAD of master branch works as well.

Then follow the instructions in the README.md in order to proceed with the compilation.

Best regards,

Simon

Greetings linphone developers,

 

I’ve just started my voip sdk journey and I tried the liblinphone basic call tutorial, but things aren’t working as expected.

 

I’ve got FreeSWITCH running on a windows server at 192.168.0.1

I’ve got a x-lite softphone running on the same server registered with address 1000.

 

I’ve got the liblinphone tutorial running on a windows 10 virtual machine

I attempt to dial the x-lite client.

Here is the results:

 

C:\Users\RTIS\Downloads\liblinphone tutorial>"Liblinphone tutorial.exe" sip:address@hidden

The freeSWITCH console output look like this:

The freeSWITCH server has a password, but this tutorial doesn’t accept one (for registration)…

 

Could I get some help with the liblinphone errors, please?

 

Thanks!

Cameron

 

ps. I went back to visual studio and found all the tutorials use deprecated methods. I swapped over to the new methods (e.g. using factory) and the same errors occur. Please consider updating your tutorials to use current methods.

pps. I tried getting ortp source from git to investigate further, but the instructions for win32 were wrong (the win32 build folder was absent). I tried downloading it anyway, but got stuck with trying to resolve cmake dependencies on bctoolkit and then polarssl (I have no cmake experience).
