Java UI for linuxcnc

Nope it wasn't that, switched to linuxcnc master, rebuild linuxcnc, rebuilt JCNCScreen.. again, same error :/

Hi,

I use linuxcnc github master as rip-installation (which is the only installation type, that works for me).

The error you get is unresolved constructor of NML class.
The only part, where I use NML is in ErrorReader.cc - and if that constructor would fail, I would not receive any error message from linuxcnc backend.
But I do get error messages from linuxcnc backend.

Therefore I stated, I don't know, what goes wrong, but I can't see any bug in my code or makefile.

Any help is appreciated a lot!

As I already wrote, I use debian stable, and for so, I use openjdk version 11 and openjdk-runtime. gcc is version 8.3.0 - don't know, what else could matter ...

When you issuein native directory, every lib should be printed with absolute path. Important are the libs from linuxcnc:

• liblinuxcncini.so.0
• liblinuxcnchal.so.0
• libnml.so.0
• libtooldata

Hi,

I just solved my problem with native layer.
May be you like to try again, whether it works for you too.

I've made a git pull on branch master of linuxcnc, then ran "make" and "sudo make setuid"
I've made a git pull on your repos, ran ant dist on the export handler and on the jcnc screen
Then I tried to run the ldd command, and the results are not like yours. 
From what I can see by inspecting the make file, is that the paths that I have under my lc folder, are not matching the ones specified in the makefile. 
This leads me to conclusion that we're not using the same version of linuxcnc? How come we can have different folder structures if we're both on linuxcnc master?
See attached a screenshot with the relevant informations: 
The tree structure in lc folder, a comment in the make file with the paths that are not correct for me, the embedded ide terminal with the result of ldd command, and the external terminal that shows on which branch I am with linuxcnc.

Please let me know your thoughts on the different lc folder structure.

Hi,

if you place a softlink into native directory, called lc pointing to root of linuxcnc, then everything is fine, even if the absolute paths are different.

Currently I have problems with internet - so I wrote from mobile phone without looking at your picture.

Your right of cause! The include paths are wrong.
I have no idea, why it compiled without problems.
Anyway - change your Makefile and I push a changed variant as soon as I can connect to github.

Thank you for your feedback!

I have that softlink.

OK, fixed Makefile is uploaded

Are you sure that your code really gets compiled? I think you may have a cache or smth.
If I move to native folder and I try to run a make command, I get the following error.
The signature from the header file does not match the signature in the c file.

Changed the signature in the header file, then ran an ant dist.
After that I checked the ldd command but still no linuxcnc libs....
The softlink is there..no idea what I'm missing :/
