Building Linphone with libjingle-0.5.6 broken

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Install libjingle and all the dependencies, including linphone
2. Modify libjingle.scons as described in libjingle-0.5.6's readme
3. Run hammer.sh

What is the expected output? What do you see instead?
The build should succeed with the Linphone capabilities built in.  Instead, I'm 
getting this error:

What version of the product are you using? On what operating system?
libjingle-0.5.6 on Ubuntu 10.10 64-bit

Please provide any additional information below.
I have attached my modified libjingle.scons

Hi,

I had the sames errors, i think it is because there was mistakes during the 
implementation of "linphonemediaengine".

For the first error you have to change the return type of the 
"cricket::LinphoneVoiceChannel::SetRingbackTone(const char*, int)" function 
from "void" to "bool".
For the second error you have to implement in "LinphoneMediaEngine" the 
"GetOutputVolume(int*)" which is pure virtual in "MediaEngine"

Maybe it is not the good solution but, now, i can call !

Thanks Guill. I also met same problem and the first error did disappear after 
changing the return type. However I don't have a clue of solving the abstract 
class problem. I'm working on libjingle-0.6.0 and there is no GetOutputVolume 
function. But it seems all the functions in linphonemediaengine class are 
abstract, and I need to implement all of them. Is that the situation? Thanks in 
advance.

What did you define in GetOutputVolume(int*)

Some of the inherited virtual function are not implemented in 
LinphoneVoiceChannel.

Adding below code in class LinphoneVoiceChannel will resolve these errors.

  virtual bool AddSendStream(const StreamParams& sp) { return true; }
  virtual bool RemoveSendStream(uint32) { return true; }
  virtual bool AddRecvStream(const cricket::StreamParams&) { return true; }
  virtual bool RemoveRecvStream(uint32) { return true; }
  virtual int GetOptions() const { return 0; } 
  virtual int GetTimeSinceLastTyping() { return 0;}
  virtual int SetTypingDetectionParameters(int, int, int, int) { return 0; }
  virtual bool PlayRingbackTone(uint32, bool, bool) { return true; }

Linphone is no longer supported.
