I had a look and its author,@Janis_Erdmanis also posted in this thread. i think the way to go is PackageCompiler → lib, then using lib either in a C++ program + Qt or in a Lazarus program.
Now that I got PackageCompiler to work I will give the latter a try the next days and report back.
(by the way, since PackageCompiler works well with Julia 1.10, I downgraded to Julia 1.10 and noticed that my programs run faster that with 1.11 when executed the first time)
Regarding Mousetrap.jl, this is a really nice UI. The point with UIs is that for our programs we spend about 80% on the UI until all knobs behave as they should, are only active when they should etc. Therefore we need a UI that is driven by either a company or an active community. Mousetrap had its last commit more than a year ago. If we encounter bugs, we would have to fix them on our own but we don’t have the manpower and knowledge to dive into UI code.
Regarding SyslabCC, I had a look, but its webpage and the linked example leads me to a blank website, with only a menu in Chinese.
