I am in my first steps with Julia and I am trying to understand its mechanisms. I took “QmlJuliaExamples-master” as a reference because I am interested in building tables with data from my DBs.

I followed the instructions in README.md and when I run include(“gui.jl”) I get the expected result. the same thing if I run from commandline julia --project=. gui.jl
Running: “Execute active file in REPL” I get tons of warnings and the result displayed is not as expected and a strange string appears: “Conacatenation, showing multiple arguments”

Running: “Run file in a new process” I get the expected result (at least I think so)

Running: “Debug file in a new process” I get error in file CxxWrap.jl
Exception has occurred: ErrorException
unknown call f introduced by ccall lowering getindex

It should be noted that vscode reports me 43 errors/warnings in StdLib.jl
