I may have found a work around for this. I was experiencing the same issue on my laptop. I’d hit build and launch, and it would crash immediately with the same message as above.
I was launching defold from the console, using Defold-linux.sh. Tonight, I finally created a gnome menu shortcut under my dev entries because I was tired of opening a console and typing in the command. Well, doing it that way seems to have fixed the issue. On a whim I did “build and launch.” Lo and behold, it RAN! So either my trick worked, or the bug was fixed. I’m running:
Version 1.2.94
(a9ec217c3e4b486c07a86c935b0cc805b6680480)
Java 1.8.0_05
So you may want to make sure you set up a shortcut in your system gui menus to run Defold, and it should work in 64 bit. There is probably a way to get it to work from the command line, but it appears this works.
[edit]
Maybe I spoke too soon. It runs, but does not accept input, I have a window that uses dirtylarry inputs and none of them activate. If I build to html it works properly. Darn.
