              Build Instructions for PJLIB/PJMEDIA/PJSIP RTEMS Port

The RTEMS port uses the POSIX abstraction layer at the moment, and has been 

tested with RTEMS 4.6 on i386 target.

Building RTEMS

---------------

I use RTEMS 4.6 on a cygwin host with i386/pc386 as target, but I think it 

should work with different RTEMS versions/hosts/targets. 

RTEMS was built with the following commands:

  $ /opt/src/rtems-4.6.6/configure --enable-cxx --enable-posix --enable-networking --enable-rdbg --enable-tests --enable-rtemsbsp=pc386 --target=i386-rtems

  $ make

  $ make install

Supported Targets

-----------------

At the moment, pjlib supports i386 and mpc860 CPU target. For other targets, 

you would need to create/tweak the appropriate "m-xxx.mak" in "build" directory

and the corresponding "m_xxx.h" header file in "pj/compat" directory.

Please refer to pjlib porting guide about how to port PJLIB to new CPU target.

Building PJLIB/PJMEDIA/PJSIP

----------------------------

Use the following steps to build the libraries:

1. Set RTEMS_LIBRARY_PATH environment variable to point to your BSP directory 

   (which is /). 

   For example (with sh):

 

   $ export RTEMS_LIBRARY_PATH=/opt/rtems-4.6/i386-rtems/pc386

2. Unfortunately pjproject's configure script is unable to create "build.mak" 

   for cross compilation (but this may change in the future), so we need to 

   create "build.mak" manually.

   The file "README-configure" has some info about the variables in "build.mak".

   For example, the "build.mak" for i386 target:

   export MACHINE_NAME := i386

   export OS_NAME := rtems

   export HOST_NAME := mingw

   export CC_NAME := gcc

   export TARGET_NAME := i386-rtems

   export CROSS_COMPILE := i386-rtems-

3. Put additional CFLAGS or LDFLAGS that are specific to your target in 

   "user.mak".

   For example, my "user.mak" looks like this:

   export CFLAGS += 

   export LDFLAGS += -Wl,-Ttext,0x00100000 -Wl,--defsym -Wl,HeapSize=0x400000

4. Build the libraries:

   $ make dep && make distclean && make

5. That should be it. The libraries should be in "lib" directory and 

   applications in "bin" directory.

Many thanks for Phil Torre , who did most of the 

initial porting and testing with pjlib etc. All credits go to him.
