devicemanager.h contains Create() function but function is not defined in devicemanager.cc

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Download libjingle-0.6.14. Copy talk folder in mylibjingle folder.
2. Update paths to libraries in VS 2010 environment.
3. Compile VS 2010 project.

What is the expected output? What do you see instead?

2>callclient.obj : error LNK2019: unresolved external symbol "public: static 
class cricket::DeviceManagerInterface * __cdecl 
cricket::DeviceManagerFactory::Create(void)" 
(?Create@DeviceManagerFactory@cricket@@SAPAVDeviceManagerInterface@2@XZ) 
referenced in function "private: void __thiscall CallClient::InitMedia(void)" 
(?InitMedia@CallClient@@AAEXXZ)

Above is one of four linker errors.

What version of the product are you using? On what operating system?
libjingle 0.6.14, win7 x64

Please provide any additional information below.
Create() function is producing linker error. Function is declared but not 
defined.

I have this problem too,can somebody help us? thanks.
By the way, why Google did not give  us a vs2010 solution directly? Then lots 
of problems in the issues can be solved.And I strongly recommend it.

From that point i tried to solve the error 2019:
error LNK2019: unresolved external symbol "public: static class 
cricket::DeviceManagerInterface * __cdecl 
cricket::DeviceManagerFactory::Create(void)" 
(?Create@DeviceManagerFactory@cricket@@SAPAVDeviceManagerInterface@2@XZ) 
referenced in function "private: void __thiscall CallClient::InitMedia(void)" 
(?InitMedia@CallClient@@AAEXXZ)

I tried:
1. to change the code C++ in the callclient.cc, in detail in tried to call 
cricket::DeviceManagerFactory::Create() to create a devicemanagerintergace 
object like mediaengineinterface ( this call create wont cause the error, but 
the 2 classes are similar to declare and initialize).
 but it still cause the LNK2019.
2. to add all necessary lib in the reference, but it still cause LNK2019. 
3. to change many other things... but still not successful.

I think there are some problems when linking from Call project (e.g. 
mylibjingle) into the jingle.lib).
I think it is not in the code, but there is another reason when linking.
Who is interested in the problem, we can make a team for that, my email is: 
ductai@tin180.com.
Thanks.

After 4,5 days hard worked with the solution Mylibjingle, I built mylibjingle 
successfully.
Here is my method:
Check file libjingle.scons, we'll see the list of all files that built by Scons.
In line:
talk.Library(env, name = "jingle",...)
there will be source of some platforms, look at these lines:
 srcs = [
               "base/asyncfile.cc",
               "base/asynchttprequest.cc",
               "base/asyncsocket.cc",
               "base/asynctcpsocket.cc",
               "base/asyncudpsocket.cc",
               "base/autodetectproxy.cc",
               "base/bandwidthsmoother.cc",
               "base/base64.cc",
...
]

We'll compare all the files in solution mylibjingle and in this list, there are 
many files was built in libjingle.scons but hasn't added into our solution 
Mylibjingle. 
We just add all classes (file .cc + file .h) that has in this list but has no 
in the list of solution.
Then rebuild again. I got the result "mylibjingle.exe" as "call.exe" built by 
Scons.
