RGMP README File

================



RGMP stands for RTOS and GPOS on Multi-Processor.  RGMP is a project for 

running GPOS and RTOS simultaneously on multi-processor platforms. You can

port your favorite RTOS to RGMP together with an unmodified Linux to form a

hybrid operating system. This makes your application able to use both RTOS

and GPOS feathures.



See http://rgmp.sourceforge.net/wiki/index.php/Main_Page for further

information about RGMP.



Build Instructions

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



1. Download RGMP from rgmp.svn.sourceforge.net:



   cd <rgmp-dir>

   

   svn co https://rgmp.svn.sourceforge.net/svnroot/rgmp/trunk rgmp



2. Configure NuttX.  For example, for the RGMP NSH configuration, do the

   following:



   cd <nuttx-dir>

   cd tools

   ./configure.sh rgmp/nsh

   cd ..



3. Edit Make.defs so that it can determine the include paths to the RGMP

   installation directory.  I made this change to <nuttx-dir>/Make.defs:



   --- configs/rgmp/nsh/Make.defs  2011-05-12 11:19:26.527273500 -0600

   +++ ./Make.defs 2011-05-12 12:52:42.847364700 -0600

NOTE: This needs to be better integrated with the RGMP build process. If

you follow the above instructions, NuttX for RGMP will compile error-free

but will fail at link time:



  LD:  nuttx.exe

  ld: cannot open linker script file /home/patacongo/projects/rgmp/rgmp/rtos/etc/x86.ld: No such file or directory
