Hello,
After a long time trying, I was able to make B4J 4.50 run on Linux Mint 18 - MATE using Crossover (for easyness because of the many trials done).

All of the software is running fine (even the Internal Designer). The sole thing I can not get is executing the compiled Jar directly from the Wine's environement because of a weird error about JavaFX :
B4X: 
Device "Intel(R) G45/G43" (\\.\DISPLAY1) initialization failed :

   ... 14 more

But the jar for a non UI app is correctly generated and usable without any problem. I will have to investigate more to fix the JavaFX before trying installing B4A.

I have set it like this :
  • Win XP bottle
  • Mono installed
  • .Net framework 4.0 and 4.0 extended
  • .Net framework 2.0
  • Direct X9 (without it I couldn't open the Designer)
  • jdk-7u79-windows-i586 (64 bits version or more recent wouldn't install)

OK, it mostly works with Crossover on Linux Mint 18.1 (Cinnamon) :
- winxp bottle (default, I think)
- wine mono
- .net 2
- .net 4

With just the above, the IDE & Designer worked fine, but I couldn't run any apps because of the missing JDK. XOver complains that JDK 7 doesn't run, and JDK 8 failed to install. So I downloaded the latest JDK 8 for Windows from Oracle and installed as an unknown app.

The install recommended I upgrade my windows version a few times from a message box with only an OK button to click. After the second or third one of these the installation appeared to hang, so I cancelled the install & restarted it. It then complained an install was already in progress, I clicked OK, then after that the JDK appeared to be there.

However, now I get a black window when I run the Designer or execute the application from within the IDE (not tried it outside yet).

Correction - the designer itself works, but the form window that shows the layout as it would look is black.
