Unable to run on linux?

[dosaki]

Hi,

I've evaluating OpenRTS to see how good it would be to implement a game. I've seen some of the youtube videos and it looked rather nice.

The problem is that I can't seem to run this on Linux. I've seen #106 but I still get a problem after the dependencies are resolved.

I'm running Linux 4.9.15-1-lts x86_64 GNU/Linux

The error that I get is:

$ ./gradlew run

The error seems to be specific to Linux though. I've noticed that OpenRTS includes some lwjgl native libraries in core/ and example/. Is it something related to this?

It seems that the dependencies are correct.

Since I have no skill in Linux and no environnement to test it, I can't be of much help here. But I have the feeling that it is much jMonkey related than OpenRTS. Maybe you can try to ask for some help on the OpenRTS forum (which is embed into jMonkey forum)

I see. I'll try just that. Thank you very much.
