ORTE - Open Real-Time Ethernet ------------------------------ What is it? ----------- ORTE is open source implementation of the RTPS communication protocol defined by Real Time Innovations (http://www.rti.com). RTPS is a new application layer protocol, targeted at real-time communication area, which is build on top of the standard UDP stack. Which targets are supported by ORTE? ----------------------------------- UNIX - Linux, Solars, MacOS, FreeBSD Windows - MinGW, CygWin, MSVC, PharLap, ReactOS, Wine (see README.windows) RTLinux - with preliminary UDP stack RTAI - with RTNet JAVA Android (see README.android) RTEMS Blackberry note: was tested on sparc-sun-solaris2.9 powerpc-apple-darwin6.8 How to compile and install it? --------------------------- Simply untar installation package into desired directory, enter this directory and issue the following commands. UserSpace compilation: ./configure make make install After this procedure ortemanager and orteping are placed in /usr/local/bin, the library is placed in /usr/local/lib and include headers in /usr/local/include. RTLinux compilation with wIP: (DEPRICATED) ./configure --with-linux=/patched_linux_dir/ --with-rtlinux=/rtlinux_dir/ --with-rtlinuxwip=/wip_dir/ make make install RTLinux compilation with onetd: (DEPRICATED) ./configure --with-linux=/patched_linux_dir/ --with-rtlinux=/rtlinuxh_dir/ --with-rtlinuxonetd=/onetd_dir/ make make install RTAI compilation: ./configure --with-linux=/patched_linux_dir/ --with-rtai=/rtai dir/ --with-rtnet=/rtnet dir/ make make install JAVA compilation: ./configure --with-java=/java_home_dir/ make make install Another way of compiling ORTE is to use OMK compilation method. See https://rtime.felk.cvut.cz/omk/ for details about OMK. Just run make in the root of the ORTE project. This will create _compiled directory, which will contain the compiled binaries as well as other files. How to start? ------------- run :ortemanager & see :ortemanager -h for usage note: ortemanager have to be running during all communication. For future work can be added into /etc/init.d/... script for starting ortemanager during boot of machine. This scripts (redhat and mandrake) are located in "orte/manager/rc/ortemanagerd". For developing a RT application, ortemnager can be running in userspace. Start it with parameter "-k 192.168.4.2". This address is the IP address of the RT application. How to test communication? ------------------------- In a shell try to type "orteping -p -s". This will create one publisher and one subscriber with the same topic and type. If you see messages like [root@localhost ORTEPing]# ./orteping -p -s sent issue 1 received fresh issue 1 sent issue 2 received fresh issue 2 sent issue 3 received fresh issue 3 then communication works. If you see only sending messages, it is a sign that ortemanager is not probably running. See "orteping -h" for usage. Now, you can develop your applications (see documentation). Obtaining the code from Git repository -------------------------------------- You can obtain the latest ORTE source code from Git repository by running: $ git clone git://git.code.sf.net/p/orte/orte Building From Git ----------------- To build ORTE code from Git, you will need Autoconf, Automake, and any tools that those utilities require (GNU m4, Perl, etc.). See the configure.in file to find the minimum versions of each of these tools. After checking out the code, you will need to perform these steps to get to the point where you can run "configure" and "make". $ make -f Makefile.git Feedback is welcome - send bug reports, enhancements, checks, money orders, etc. to ORTE maintainers . The mail will go to Petr Smolik, Michal Sojka and Pavel Pisa.
