Generating RexHMI

marcusallen10@googlemail.com · 2018-01-31 16:45:03

Hi,
I’m working through the getting started manual and have hit a snag. The test algorithams work fine and compile.
However the HMI generating fails on my getting started example and all of the other examples.
Error :-

My getting started project:-

Generating RexHMI ...
Source: C:\Users\Marcus Allen\Documents\RexProjects\hmisrc
Destination: C:\Users\Marcus Allen\Documents\RexProjects\hmi
Error: unable to start "GenRexHMI.py "C:\Users\Marcus Allen\Documents\RexProjects\hmisrc" "C:\Users\Marcus Allen\Documents\RexProjects\hmi" "--clean" "--copy""
Error: Generation of RexHMI failed: -1

example projects:-

Generating RexHMI ...
Source: C:\Users\Marcus Allen\Documents\rex2\hmisrc
Destination: C:\Users\Marcus Allen\Documents\rex2\hmi
Error: unable to start "GenRexHMI.py "C:\Users\Marcus Allen\Documents\rex2\hmisrc" "C:\Users\Marcus Allen\Documents\rex2\hmi" "--clean" "--copy""
Error: Generation of RexHMI failed: -1

Can any one help.

Hi Marcus,
sorry to hear about the difficulties. Can you please specify what operating system are you using and what version(s) of REX is installed on your PC? Thanks!

Kind regards,
Jaroslav

Hi,

Thanks for the prompt reply.
I am running Windows 7 on a Mac as a virtual machine.
I can download to the pi and monitor the algorithms.
I am using the latest version of REX 2.50.5.
Thanks

Hello Marcus,
we are using python for building the HMI, the python interpreter is part of the installation. Have you install the HMI Designer? If yes can you please open the HMI Designer and run Extensions -> REX HMI -> Version info. If about window opens you will see the version of the python and we will know that interpreter is not the issue. Otherwise we will try to find the issue elsewhere.

Regards
Ondrej

Hi,

HMI designer is noted in the menu but is not installed.

Do I need to re install REX.

Edit :-

I’ve re-installed REX software. I think the previous install was “compact” rather than
“full” . My bad. I’ve done a full install now. When I’m back to my computer I’ll
Check if this has cured the problem. I’ll let you know the outcome.
Thanks for the help so far

Marcus.

Hi,

Ive re installed and now REX HMIdesigner is now installed.

I still get an error when trying to compile the getting started for Monaco Hat example.

error :-

The HMI Designer version gives :-

Hi Jaroslav,

Thanks, I’ll try that when I am at my machine. Probably during the week end.

Hi Jaraslov,

Problem solved. The missing dll was the final problem. Thanks for the prompt replies and assistance.
