Building PJSUA2

The PJSUA2 C++ library is built by default by PJSIP build system. Standard C++ library is required.

The following sections applies to building SWIG Python, Java, or C# modules.

Common Requirements

On Linux/MacOS X/Unix, you need to build PJPROJECT with -fPIC option. You can either put it in user.mak file in root pjproject directory like this:
```
CFLAGS += -fPIC
```
or you can specify it when calling configure:
```
./configure CFLAGS="-fPIC"
```
Then rebuild pjproject.
Install SWIG

For Debian based distributions (such as Ubuntu):
```
sudo apt-get install swig
```
For Windows and other platforms please see https://www.swig.org/download.html

Building Python SWIG Module

Install SWIG as shown above.
Install Python development package:

For Debian based distributions (such as Ubuntu):
```
sudo apt-get install python3-dev
```
For other platforms, TBD.
Build:
```
cd pjsip-apps/src/swig/python
make
make install
```
Note

The above will install the module to user’s site-packages directory.

If you’re currently on a virtualenv, run python setup.py install instead.
Test the installation:
```
$ python3
> import pjsua2
> ^Z
```

Building Java SWIG Module

Install SWIG as shown above.
Install JDK.

Build:

cd pjsip-apps/src/swig/java
make
make install

TBD.

Building C# SWIG Module

Install SWIG as shown above.
Install .. (TBD)

Build:

cd pjsip-apps/src/swig/csharp
make
make install

TBD.
