<p>I am running Libero SoC on a CentOS Docker Container (CentOS Linux release 7.9.2009 (Core)). This container will be used to build FPGA code within a CI/CD pipeline. When I attempt to execute a script (that simply prints <code>&quot;Hello, world&quot;</code>) with the command
<code>libero SCRIPT:printhelloworld.tcl</code></p>
<p>I receive the following error:</p>
<pre><code>libero_bin: cannot connect to X server
</code></pre>
<p>I would not have expected libero to require an X server just to run a .tcl script.</p>
<p>Thank you.</p>

How are you running the container (syntax)? Could just need something like `-e DISPLAY=$DISPLAY -v /tmp/.X11-unix:/tmp/.X11-unix` ...also, see https://stackoverflow.com/questions/43613474/using-x11-forwarding-for-docker-containers

# CentOS Docker Container running Libero SoC: Unable to to connect to X Server

(Asked by: username_0 on 2021-11-23)

I am running Libero SoC on a CentOS Docker Container (CentOS Linux release 7.9.2009 (Core)). This container will be used to build FPGA code within a CI/CD pipeline. When I attempt to execute a script (that simply prints "Hello, world") with the command
libero SCRIPT:printhelloworld.tcl
I receive the following error:
libero_bin: cannot connect to X server

I would not have expected libero to require an X server just to run a .tcl script.
Thank you.
