Problems launching magic gui

[oharboe]

Normally, I can launch a GUI from within Docker on my desktop by running the command below, but I get an error message.

I run Ubuntu 18.04.

$ docker run --volume="/run/user/$UID/gdm/Xauthority:/root/.Xauthority:rw" --env="DISPLAY" --net=host --interactive -t openroad/alpha-release
[root@davos /]# magic
Error in startup script:

@RTimothyEdwards Any quick pointers you can think of? Not sure if it's related to the changes I made.

I'll continue looking into this

[RTimothyEdwards]

I don't even see a specific error listed "(default value for "-font" in widget ".text")" does not sound like an error. My best guess is that the container is missing fonts for Tk, meaning a problem with the Tcl/Tk install. But Tk should be able to fall back on X11 fonts, and it would be surprising to find that the container didn't have X11 fonts installed somewhere. . .

[RTimothyEdwards]

FYI, the error occurs inside the "tkcon.tcl" script, which is magic's console window in interactive mode under the Tcl/Tk interpreter. Since you have been using magic in batch for OpenROAD applications, you may not have noticed if anything was wrong with the interactive version. Technically, I would not suppose that OpenROAD is under any obligation to support interactive use of Magic within OpenROAD, but it would be nice to have that ability.

Thanks for the hints. I'll do some more debugging. I have been able to run the GUI as packaged on CentOS 6/7. I wonder if this something to do with docker or the docker image configuration.

@oharboe Does the docker image have tk installed? Also is the docker image running ubuntu 18 or is it the docker host.

[oharboe]

the docker image is openroad/alpha-release, so you probably know what it has installed.

i am running the command from nondocker ubuntu 18.04 desktop.

Ran into this, got past it by via yum install xorg-x11-fonts*, now have magic successfully running in Docker on macOS!

(Trying to compile natively met problems, also related to X. )
