How start write new GUI? was created by Vic
I am sorry for my english.

I start to study EMC.

I take ini file with parameters:
[DISPLAY]
DISPLAY = mini

And copy file mini.tcl to mini2.tcl and change setting in ini file:
[DISPLAY]
DISPLAY = mini2

And recive error:
Starting EMC2 DISPLAY program: mini2
Can't execute DISPLAY program mini2  
Shutting down and cleaning up EMC2... 

I don't change any text in file mini.tcl, only copy it:
-rwxr-xr-x 1 1006 root 137462 2011-04-19 15:22 mini2.tcl
-rwxr-xr-x 1 1006 root 137462 2011-04-19 15:22 mini.tcl 

What I have to do to start new GUI?

AFAIK you need to try that with a git checkout and rebuild after making your changes. I'd assume that changing the name of mini will fail as it will not get built unless you modify the make/submake files and you have to be pretty good to do that. So the easy option is just get a git checkout and modify mini then rebuild.

Do a search for git on the wiki site for instructions on getting a git checkout.

Thanks

Now I make my GUI with name 'mini' and test it.

I thought program take GUI name from ini file and use it

But your way is complex for me now

yes it takes the GUI name from the ini file.

BUT

the mini interface (and tkemc) are special interfaces, as they are tcl/tk interfaces. As such you cannot execute them by themselves. So the runscript looks for known names (tkemc and mini) and starts tclsh (the tcl shell) with mini.tcl as the program which needs to be executed.
So your easiest way to do it is to work on mini.tcl, and keep the name.
Otherwise you need to edit 'emc' the runscript and add your interface name to the list of recognized tcl/tk GUIs.

Alex

I think that Tcl is interpreted not compiled, so it might not be necessary to recompile.
The first test I would do would be to edit mini.tcl in some minor way (change the spelling of a button) for example and see if that change happens when you start the program

Now I create my small interface and it work

Yes, i name it 'mini.tcl'

But I found one bad thing:
( so bad thing is in axis GUI )

when I work in manual mode and want continuous movement, program ( and connected device ) move to some distance ( 8mm for me ) and stop movement ( i press button on interface and not stop pressing )

My code work like:
bind [set "button"] <ButtonPress-1> "emc_jog $axisToJog $jogSpeed "
bind [set "button"] <ButtonRelease-1> "emc_jog_stop $axisToJog"

Does anyone seen this behavior?

Now I found sring which run mini intarface in emc.in ( Am I right? ):
case $EMCDISPLAY in
  tkemc|mini)
    # tkemc and mini are in the tcl directory, not the bin directory
    if [ ! -x $EMC2_TCL_DIR/$EMCDISPLAY.tcl ] ; then
	echo "Can't execute DISPLAY program $EMC2_TCL_DIR/$EMCDISPLAY.tcl $EMCDISPLAYARGS"
	Cleanup
	exit 1
    fi
    $EMC2_TCL_DIR/$EMCDISPLAY.tcl -ini "$INIFILE" $EMCDISPLAYARGS
    result=$?
  ;; 

but not test it yet with my GUI name

That looks like the error message you saw, and looks like an explanation.
