If you run into the error message "Could not find a file typing rule to perform the requested action" when double-clicking a program binary, it means that binary is lacking a file type tag. Without that tag, the IRIX file type ruleset won't know how to launch that binary from X.
167

Check the tag of the binary:
Code:
$ tag xhello
xhello is not tagged
Quick solution: tag your binary as generic application:
Code:
$ tag 0x0 xhello
$ tag xhello
xhello is tagged with Octal: 00  Decimal: 0  Hex: 0x0
168

Notice how the icon of the binary changed. On double-click it will launch.

Explanation: Behold /usr/lib/filetype/system/sgicmds.ftr that holds information on how to open the binary, its icon, etc.
Code:
TYPE GenericWindowedExecutable
    MATCH       tag == 0x00000000;
    LEGEND      :216:Unix command
    SUPERTYPE   Executable
    CMD OPEN    $LEADER $REST
    CMD ALTOPEN launch -c "$LEADER $REST"
    CMD DROP    $TARGET $SELECTED
    ICON        {
        if (opened) {
            include("../iconlib/generic.exec.open.fti");
        } else {
            include("../iconlib/generic.exec.closed.fti");
        }
    include("iconlib/windowExec.fti");
    }
If the tag is 0x0 this rule matches and an appropriate icon from the iconlib is selected.
For more, see man ftr

Example buttonfly:
Code:
$ tag /usr/demos/Demo_Interfaces/Buttonfly/buttonflyAudio 
/usr/demos/Demo_Interfaces/Buttonfly/buttonflyAudio is tagged with Octal: 0110204  Decimal: 36996  Hex: 0x9084
There's a rule for tag 0x9084 in /usr/lib/filetype/system/sgidemos.ftr

Code:
TYPE ButtonflyAudio
    MATCH       tag == 0x9084;
    LEGEND      :uxsgidemo:49:Buttonfly
    SUPERTYPE   Executable
    CMD OPEN    cd /usr/demos; $LEADER
    CMD ALTOPEN $LEADER
    ICON {
        if (opened) {
            include("../iconlib/generic.exec.open.fti");
                 include("iconlib/Buttonfly.music.open.fti");
        } else {
            include("../iconlib/generic.exec.closed.fti");
                 include("iconlib/Buttonfly.music.closed.fti");
        }

    }
Your own rules should go into /usr/lib/filetype/local/

Thank you for this excellent explanation! Really appreciate you going to all the trouble of making screenshots and step-by-step.
