How to build PJSUA2 (swig) with Visual Studio 2015

问题

I try to compile PJSUA2 for Python. I could manage to compile the source with Visual Studio 2015 Community edition.

My question is, how can I install the Python module now?

The guide suggests to use make and make install. I tried to install also minwg, but it is not working as the project was compiled with VS.

I have also tried to compile with minwg, but I never could succeed due to undefined requirements. Also official PJSUA guide recommend to use VS for Windows.

Following settings have been applied to build from source:

Swig location has been added to path
JAVA_home system variable has been added
Java location has been added to path
Empty pjlib/include/pj/config_site.h has been created
Opened source in VS 2015 Community (all suggested VS package and module has been installed)
Set following project to do not compile:
- pjsua_cli_uwp_comp
- pjsua_cli_wp8
- pjsua_cli_wp8_comp
Set swig_java_pjsua2 to build.
Add following folders to swig_java_pjsua2 VC++ include directories
- c:\Program Files\Java\jdk-11.0.2\include
- c:\Program Files\Java\jdk-11.0.2\include\win32

I could make a workaround to compile pjsua2 for Python 3.7. If you have a better solution or just suggestion to this workaround, let me know

Preconditions:

List item
Download and extract swig (swigwin 4.0.0)
Download and install JDK
Download and install Python (Python 3.7.3 x64) and set at custom installation:
- tick "Add Python to environment variables"
- tick "Precompile standard library"
- tick "Download debugging symbols"
- tick "Download debug binaries (requires VS 2015 or later)"
- set custom path if you want
- add swigwin location to system path
- add Python location to system path
- add JAVA_HOME system variable
- add %JAVA_HOME%\bin to system path
- Install Visual Studio 2015 Community edition

Steps:

Download and extract pjsip 2.8
Create empty config_site.h under pjlib/inlclude/pj/ folder
Open pjproject-vs14.sln in VS
There will be an unsupported warning window, press OK
At the "Install Missing Features" windows, press install
VS installer will be started, and VS has to be closed to complete installation.
I have also added "Windows 10 SDK (10.0.10586)" to the installation.
I have also enabled developer mode on my Windows 10, but this could be optional
Open project again in VS
Set project to Release and x64 on the top dropdown
Right click on the solution, and go to Configuration Properties> Configuration
Remove all uwp and wp8 related projects from selection, like pjsua_cli_uwp_comp, pjsua_cli_wp8_comp
press OK, and build solution
I have had 34 succeeded and 0 failed solution after build.
Add following lines to pjsua2.i in pjsip-apps/src/swig folder
```
%inline %{
pj_ssize_t new_pj_ssize_t(int s) {
   return (pj_ssize_t) s;
}
%}
```
this extra inline swig function provides workaround for create recorder issue
Open a command line (powershell did not work for this)
go to pjsip-apps/src/swig/python

Execute following command:

swig -I../../../../pjlib/include -I../../../../pjlib-util/include -I../../../../pjmedia/include -I../../../../pjsip/include -I../../../../pjnath/include -py3 -c++  -python -threads ../pjsua2.i

Add new "Empty Project" (Visual C++) to solution with swig_python_pjsua2 name
Add libpjproject and pjsua2_lib as reference to this new project
Right click on the Header Files>Add>Existing Item...
Add pjsip-apps\src\swig\pjsua2_wrapp.h
Add a "new filter" to the project with name "Generated Code"
Right click on "Generated code" and add new existing item.
Add pjsip-apps\src\swig\pjsua2_wrapp.cxx
Right click on the project and Linker>Input
Add "Ws2_32.Lib" to "Additional Dependencies"
Go to "VC++ Directories"
Add following folder to include path(I have used full path!):
- c:\python37\include
- pjnath\include
- pjsip\include
- pjmedia\include
- pjlib-util\include
- pjlib\include
Add following folder to Library Directories:
- C:\Python36\libs
Set at General:
- Target Name: _$(ProjectName)
- Target Extension: .pyd
- Configuration Type: Dynamic Library (.dll)
Go to properties of the solution, and select swig_python_pjsua2 to build
Right click on swig_python_pjsua2 and build
Build should complete successfully
You will need to file to use pjsua2 library in python.
pjsua.py located under pjsip-apps/src/swig/python
x64/Release/_swig_python_pjsua2.pyd (rename this to _pjsua2.pyd)
To test, copy those to file into a folder, start python from same folder and type:
- import pjsua2
