Hi @kevinuav - any resolution to this Mac issue? I am experiencing the same thing on Monterey 12.0.1

Tnx!

[mengchaoheng]

build in win11 is the same error

[hagen6835]

I also ran into this issue on mac!

Tried installing java 6+ several ways to no avail

[mengchaoheng]

On mac is recommand to install (build from sourse) plotjuggler, it can build from source, but I can not build success too. In the end I can only use these software on virtual machines.

[kevinuav]

I can just use plot juggler in windows now.

"""

but results are
