BPMN & Modeling Discussion & Questions

I am trying to run modeller on Linux ec2-instance but getting following error while trying to execute camunda-modeler

./camunda-modeler: error while loading shared libraries: libxshmfence.so.1: cannot open shared object file: No such file or directory.

I am using camunda-modeler-4.11.1-linux-x64 distribution

Hi @rahulnanda24
What Linux distribution are you using?

3

Hi @Alex_Voloshyn
camunda-modeler-4.11.1-linux-x64

4

@rahulnanda24 I’ve asked about EC2 Linux distribution, not the Modeler. Is it RedHat, Ubuntu, etc?

5

@Alex_Voloshyn
Oh My bad! ,It is ubuntu

6

Can you execute the following steps and give it another try with Modeler?

Update the package index:
# sudo apt-get update
Install libxshmfence1 package:
# sudo apt-get install libxshmfence1

Can you try to execute export DISPLAY=:0 and try again?

@Alex_Voloshyn
No, I am getting the same error.

10

Can you provide the output of the following command? lsb_release -a

11

No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 20.04.3 LTS
Release: 20.04
Codename: focal

12

Is it Ubuntu Desktop(with GUI) or Server version(without GUI by default)?

13

it is server version (without GUI)

14

Ok. I do not have experience with the setup of Modeler on the server version. Maybe other guys will be able to help you.
