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 :

Spoiler: Error

B4X:

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)

tested with linuxmint18.1+crossover16+winxpbottle+wine mono+dotnet2&4 the b4j4.7 will run with no error and inner designer show normally

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.

Got around the blank debugger window by using the Bridge trick (documented elsewhere on this forum), but for anyone else reading this Linux Mint 18.1 does not install JavaFX with OpenJDK.

You need to :

sudo apt-get install openjfx
