Embedding ngcgui in EMC 2.4.x

I get this error when I start LinuxCNC.

"<simp.ngc> must be in search path
Current Directory: /home/submicro/linuxcnc/configs/MiniMill_inch
Search Path:
../../../nc_files
../../../nc_files/ngcgui_lib
../../../nc_files/ngcgui_lib/utilitysubs

Checking for:
[RS274NGC]SUBROUTINE_PATH in ini file:
/home/submicro/linuxcnc/configs/MiniMill_inch/MiniMill.ini

Restart after fixing file"


Help appreciated

Looks like you need to change the location of the sub files or the search path to them.
This may help...

I often put mine in nc_files

That link is what I followed trying to get it working. I'm using 10.04 with linuxcnc2.5 The sim works but, getting it working with my actual setup has proved difficult. In my ini file I used relative paths i.e.
SUBROUTINE_PATH = ../../../nc_files/ngcgui_lib:../../../nc_files/ngcgui_lib/utilitysubs
USER_M_PATH = ../../../nc_files/ngcgui_lib/mfiles
The file it's looking for are in those paths. I checked.

Some of the sample subroutines rely on other subroutines so you have to have them all in the correct place. Comment out all of the subroutines except a simple one and see if you can get the syntax correct. I just use the actual full path to mine... attach your ini file for us to look at.

Hi

In my ini file I used relative paths

I would advise, don't, unless you know what PWD is and where the routine searching is starting from, it is a short cut to madness.

When I wrote my ngcgui subs, I pretty soon came to the conclusion that the only thing that actually works, is using the directory pointed to by PROGRAM_PREFIX =

For that reason, all my subs are in their own sub-directories but sym-linked to ~/emc2/ngc in my case.

For the same reason I specify explicitly the paths eg
NGCGUI_SUBFILE = ~/emc2/ngc/pcd.ngc

This setup gives me zero problems, I never touch any files in ~/emc2/ngc and do any editing or code changes to the subs in their own named sub-directories, which ensures I am always sure exactly what it is I am editing.

regards

In 2.4 I came to the same conclusion as you about the directory structure and used the directory pointed to by program prefix. In 2.5 it is much better behaved and I placed all my subroutines in the /subroutine directory under emc2.

In my ini I have:
[DISPLAY]
...
NGCGUI_SUBFILE = /home/john/emc2/subroutines/face.ngc

[RS274NGC]
SUBROUTINE_PATH = /home/john/emc2/subroutines

I will have to try that John.
Because mine 'just work', I haven't done anything to them since I wrote them.

A lot of features were consolidated and repaired in 2.5, this is probably one of them.

regards

Yea, if it ain't broke don't fix it is my motto too...

John

Thanks guys that did the trick! No more relative paths for me

Glad you got it sorted out.
