I get the same errors on CentOS 5 as you folk do on Ubuntu, so it's nothing special there.

So... what did Phonic do differently than everyone else? A guy in the bukkit IRC has it working on debian 6 aswell.

Hrm...

System.BadImageFormatException: An attempt was made to load a program with an incorrect format. (Exception from HRESULT: 0x8007000B)

Fixed it :smile.gif:
Quite easy,
I downloaded http://www.ikvm.net/download.html and then grabbed the dll files from the bin_x64 dir and used them to replace the files that came in the zip. It runs now.

Phonic, how did you get those pretty graphs?

I usually just try stuff and then ask questions but: I have the zencraft folder (with bukkit.exe and all the dlls). Either I missed some directions or everyone else just knows where to put the exe and the dlls and how to incorporate bukkit.exe into the startup process (same batch file with bukkit*.jar replaced by bukkit.exe or ???). I don't. Could you tell me how you did it (since I think you also have Win7 64)? Thanks for your time, regardless.

Anyone managed to get a client to run with IKVM?

I came here to ask for a 493 version and saw your question. I hope i answered it.

Plus hereby my request for a 493 version.

Thank you very much. That is a great help.

Still looking for a way to get this working on ubuntu 10.04

Edit:

mono --optimize=shared ikvm.exe -jar craftbukkit.jar nogui

Have fun with that.

Edit2: It was a bug in mono, it should be fixed in the master branch of the git repo now. you shouldn't need to use the optimize flag with 2.11.

Works for me on CentOS. Huzzah!

I'm a Linux newbie running my server on a VPS hosting service using CentOS, so I'd appreciate if anyone could tell me how to install the dependencies this needs to work. Thanks.

When I open the zip file it makes a cpkg file that makes a zip file that makes a cpkg and it just keeps going.

WTF? What am I supposed to do?

Click the notch :wink.gif:

Yes, I'm very well aware with how google works dude. This is taking me to links on installing versions of Mono that people aren't even talking about in the thread, and furthermore most places assume you have an intermediate understanding of Linux whereas I'm completely new.

I've already googled the hell out of this, and I generally do before asking a question.

Okay, with help from SynMonger, I was able to get it working. The only problem is, all the plugins I'm using that use SQLite databases started throwing errors (LWC, iConomy, Persistence). Everything else seemed to work fine though. Is there any way around this issue?

Here's one of the errors:

Again, anything not using SQLite is working fine.

So first try failed, running err.. Debian I believe.

Hmm, old version apparantly, could always try to upgrade the distro, I'll update the post when I've tried.

So, yeah, it looks like the SQLite issue is no fault of my own, the connector simply just won't load when you're using IKVM instead of Java. Supposedly you can compile the connector into a DLL file to make it compatible, but I wouldn't know how to get it to load. If anyone with some technical expertise can fix this issue my server will be able to use this.

I assume that this will not work on a mac?

I haven't tested it though, I've been unable to get this working on linux so I'm not even going to bother trying it on my mac.

Odd, LWC is running fine here, had my 493 server running overnight. hardly noticalbe.
Did you try fresh or over an old server?

I did not start fresh. What OS are you using? I'm using Linux so there may be some discrepancy there.

I still cannot get this to work. I ran the line as listed (changed ikvm.exe to ikvm) in openSuSe 11.3, and it returns:

"Cannot open assembly 'ikvm': No such file or directory"

when I have ikvm version 0.42.0.6
mono 2.6.4
and SUN Java JRE 1.6.0_24b-07 (not OpenJDK)

I dont feel like downloading another OS just to run this.

Also, is mono and ikvm available/usable in BSD? My minecraft server (also a vlc server for my tv) is running pc-bsd(only because i need video output, otherwise would be freebsd)

I got this (sort of) working on Ubuntu 10.04. Using "ikvm -jar craftbukkit.jar" doesn't work, it gives the exact error that MonsieurApple gets. I extracted the IKVM binaries to my root folder, and tried "mono ikvm.exe -jar craftbukkit.jar" which also crashes with that error. I then tried "mono --optimize=shared ikvm.exe -jar craftbukkit.jar" which successfully passed the "preparing spawn" thing when starting server, although it was REALLY slow, and my plugins loaded exceptionally slow as well. After that it crashed :\

Here's the error of the last crash:

Oh well :|

Easy as saying "apt-get install ikvm" and it was installed. Love Debain.

Yeh, seems to be working pretty good so far. CPU usage seems to be dramatically reduced, same with RAM. Using CraftBukkit too.

Would there be any way to use this with biomterrain mod?
