== Choosing betwen Autoconf and legacy configure ==

The [wiki:Getting-Started/Autoconf Autoconf system] can be used to cross compile.

The old PJLIB build system can still be used for building PJ libraries, for example for RTEMS target. Please see [http://www.pjsip.org/pjlib/docs/html/porting__pjlib__pg.htm Porting PJLIB] in [http://www.pjsip.org/pjlib/docs/html/main.htm PJLIB Reference documentation] for information on how to support new target using this build system.

== Supported Targets ==

The older build system supports building PJ libraries for the following operating systems:

    * RTEMS
    * Linux
    * MacOS X
    * Cygwin and Mingw

And it supports the following target architectures:

    * i386, x86_64, itanium
    * ARM
    * mips
    * powerpc
    * mpc860
    * etc.

== Other Targets ==

For other targets, specific files need to be added to the build system, please see [http://www.pjsip.org/pjlib/docs/html/porting__pjlib__pg.htm Porting PJLIB] in [http://www.pjsip.org/pjlib/docs/html/main.htm PJLIB Reference documentation] for details.
Invoking the Build System

To invoke the older build system, run the following:
  	
{{{
$ cd pjproject
$ ./configure-legacy
$ make dep && make clean && make
}}}
