I can't build linphone 3.8.5 on visual studio development environment

Question

Can anyone tell me how to build linphone 3.8.5 on Visual studio?
I am trying to do this for one month, but failed. I have tried in many ways by reading many answers, but failed. May somebody help me to build it ?

Answer 1

Create a project

1. To create a project, go to "File" menu -> New -> Project...
2. Select the "Win32 Console Application" template in the section "Visual C++" -> "Win32" and give a name to your project e.g. "Liblinphone tutorial". Next click "Ok".
3. Now, the wizard for Win32 Applications comes out. Click "Next", check the "Empty project" box and click "Finish".
4. You should now have a project called "Liblinphone tutorial" and a new target identically named. You may rename this target into "Basic call".

Configure a project to use liblinphone

1. Download the ZIP archive of linphone SDK and extract it into your Visual Studio project directory. In our case, it is placed in Documents\Visual Studio 2013\Projects\Liblinphone tutorial\Liblinphone tutorial. Be care to name the extracted directory as "liblinphone".
2. In Visual Studio, right click on the "Basic call" target and click on "Properties"
3. Go to "C/C++" section and then "General". Add the directory "liblinphone/include" in the "Additonal Include Directory" field by using the editing wizard.
4. Go to "Linker" -> "General" section and add the "liblinphone/lib" directory to "Additional Library Directories".
5. Go to "Linker" -> "Input" section and add the folowing libraries into "Additional Dependencies": ortp.lib mediastreamer_base.lib mediastreamer_voip.lib linphone.lib

Compiling

Add file called name.c in the source files of your target and fill it with the source code of the Basic call tutorial

You can now build your project by right clicking on the target to build and clicking on "Build"

Executing and debuging

To be able to execute the generating binary file, you need to set the PATH environment variable. Go to the property panel of the target and then in the "Debuging" section. Edit the environment field and add the following line:

PATH=C:\Users\<user_name>\Documents\Visual Studio 2013\Projects\Liblinphone tutorial\Liblinphone tutorial\liblinphone\bin;%PATH%

The "Basic call" program need a SIP address as argument. You can specify it by editing the "Command argument" field. For instance, you may write sip:bot.linphone.org.

You can now execute the program by clicking on the "Local Windows Debugger" in the main interface.

Note : Mediastreamer loads its plugins relatively to the root of the SDK. If you need features provided by such plugins, for example the support of OpenH264, you may set the working directory to the location of the SDK. That can be done by going into the "Debuging" section in the property of your project.
