Python linuxcnc.stat() showing no result.

Short:
The other day i was making a python script to see currently opend ngc file, in case if I'm running a global LinuxCNC installation i can read the current file, but for a local installation of LinuxCNC I'm getting an empty string. What could be the problem.


Long:
On my laptop i have a simulation package of LinuxCNC installed. The installation was done pulling the LinuxCNC from GitHub and making a deb package, as i wanted to make a system wide installation.

Often there are other branches of LinuxCNC that solves my problem, hence I download them and make a local installation on my laptop.

To start a global installed file i directly type linuxcnc in my shell script.
Whereas for a local installation i have to cd to the location and then to script folder then i type ./linuxcnc. Everytime things work fine.

The other day i was making a python script to see currently opend ngc file, in case if I'm running a global LinuxCNC installation i can read the current file, but for a local installation of LinuxCNC I'm getting an empty string. What could be the problem.

Any help will be appreciated.

Thanks,

Can you explain what you mean by "global" and "local"?

Just a guess from the context, "global"=standard full installation of Linuxcnc, "local"=RIP (run in place).
Is that what you mean Kunal?

Yep. Global is standard installation, and local is RIP.

Are you starting your Python code from the same environment (ie command line terminal) as LinuxCNC?

I start LinuxCNC from a terminal window, then again i open a new terminal window type python there i import the linuxcnc python module and do what I want to do.

For the timing i have made a glade app which i start with my LinuxCNC configuration.

In that app when I try to check current position just after homing, i'm getting 3.58... for x and y though its x and y are at 0. But when i make a move i get correct position.
