RE: [Rtl]RTLinux Install HOWTO

Title: Message

Interesting; I couldn't find anything in your instructions that would have created those links.  To make this work on our systems, we had to do something like

 

ln -s   /usr/src/rtlinux/rtlinux-3.1/scripts/rtlinux         /usr/local/bin/rtlinux

ln -s   /usr/src/rtlinux/rtlinux-3.1/scripts/rtl-config     /usr/local/bin/rtl-config

I can go back and add the stuff that you've suggested, but

when I installed RTLinux, it did create /usr/bin/rtlinux as a link

to /usr/rtlinux-3.1/bin/rtlinux for me.

Your web page does cover some of the details better than the original. I wish I'd had a copy when I first tried installing RTLinux.

 

On Step 1, you might consider adding instructions for those who've already installed Red Hat Linux;  check to see if kgcc is already installed:

   which kgcc

If so, there's no need to install it again. If not, the packages you list in step 1 need to be installed, or kgcc needs to be setup as a link to gcc 2.95.3 if it exists:

   ln -s   <<<path to gcc.2.95.3>>>   /usr/local/bin/kgcc

 

You might want to include the check for "rejects" that Phil Wilshire addressed in his installation instructions. I don't know if the current RTLinux 3.1 patch will still generate these .rej files if a problem is encountered, but it wouldn't hurt:

 

    cd /usr/src/rtlinux/rtlinux-3.1

    find ./ -name *.rej

If this finds any files, there's a problem in the installation.

 

It would be nice to include a note that you can only patch the 2.4.4 kernel once; if you need to redo the patch for any reason, remove and build it (being very careful on the  "rm -rf linux" step):

    cd /usr/src/rtlinux

    pwd   # just to be safe, check

    ls -l    # just to be safe, double-check

    rm -rf linux

-- and then start over at step 4 in your sequence.

 

Finally, and perhaps most important, this installation will not create a "rtlinux" file in /usr/bin, so the post installation steps will not work as written. That's probably a script you wrote to replace or augment the

   /usr/src/rtlinux/rtlinux-3.1/scripts/insrtl

script that is installed to load the RTLinux modules.

   

    Thanks...

Guys, I made up a webpage that explains how to set up Open RTLinux 3.1 with

RedHat 7.1 or 7.2. I haven't tested it with 7.3 yet, but it may work the same. If you

follow these directions explicitly, it should work for you.

If there are any errors, please let me know.
