In addition to the C compiler, you'll also need a set of system libraries. These libraries are used by Asterisk and must be installed before you can compile Asterisk. On most operating systems, you'll need to install both the library and it's corresponding development package.
A list of libraries you'll need to install include:
- OpenSSL
- ncurses
- newt
- libxml2
- Kernel headers (for building DAHDI drivers)
We recommend you use the package management system of your operating system to install these libraries before compiling and installing libpri, DAHDI, and Asterisk.
