MC-Server on Raspberry Pi

[DJburner]

Can i compile woth msvc on debian too?

[xoft]

No, MSVC is windows-only.

Please try compiling rev 701, I have tried to fix all gcc-related errors, it compiles fine on my virtual ubuntu now.

[DJburner]

Okey i try it again

Thanks for your help!

[xoft]

So, how did it go? Did it compile? Did it run? Is it still slow? I'd like to hear

[DJburner]

Yes, i donwloaded the r707 and compiled it, it took hours
Bad question but where is my Programm now? And how can i run it?
Does it use also a little bit java or is it completle made in c++

DJburner

[xoft]

Wow I had no idea compilation would take so long

Your program should be in the same folder where you ran the "make" command and it should be called MCServer (note the lack of any extension). You should be able to run it using a "./MCServer" command.

No, it doesn't use java at all. It's mostly C++ with a few bits (plugins) written in Lua.

[DJburner]

Ah ok, o knew that its a thing called mcserver but i thought its a folder how other server

And with which programm you make mcserver? Visual studio 2010?
I am using visual studio express basic i like basic, i made a webbrowser with it

But back to the topic, i will start it now

It is running,
4chunks/s
Okey,
Server is running, but i cant test, im on my tablet.
Tomorrow i will try it. And the 9x9x9 tnt test
And tomorrow my computer is here:
I7 3770k
16gb ram
Watercooling
120gb ssd
2tb hdd
And and and

And you order a raspberry pi too?

Woooh,

I restarted and it took only 5 seconds, but i have only a settings.ini with port:25565, nothing else. Is that right?

[xoft]

With a restart, the chunks are already generated (inside the world folder) so it takes much less time. But the generator speed is terrible.
I just got my RasPi, and I found out that compiling in debug (using "make" command) gives about 3-4 chunks per second generator performance, and compiling in release (using "make release=1" command) makes the server crash upon startup for unknown reasons. Probably some gcc optimization that doesn't work on the Pi. I brought the entire thing to work with me so that my colleagues can play with it, they might give me some help with this as they're more Linux-educated than me. I really hope to see the release build running, it should have a decent speed increase over debug (on Win, the difference is about 8-fold)

Hello!

I got it up and running (r709, release build using "make -f GNUmakefile release=1") and the following output from starting the server with an empty world folder (world generaiton needed):

To compile the release i altered the GNUmakefile starting at line 27. I don't know if this is necessary, but i just wanted to make sure that the code is optimized for the RasPi.

Code:

ifeq ($(release),1)
CC_OPTIONS = -s -O3 -pipe -mcpu=arm1176jzf-s -mfpu=vfp -mfloat-abi=hard
CCE_OPTIONS = -s -x c -O3 -pipe -mcpu=arm1176jzf-s -mfpu=vfp -mfloat-abi=hard

You mentioned to tweak the world.ini... what can be done there to speed things up? Havent played with multiple clients yet, just had time to try this out yesterday evening. But looks promising. CPU load goes up to 95% when generating stuff, ist absolutely playable solo!
GREAT WORK MC-Server team!!!

oh, and btw: i did post a summary of my minecraft server experience on the RasPi on their official forum.. hopefully attracting more interest here: http://www.raspberrypi.org/phpBB3/viewto...35&t=13114

My RasPi-Specs are: Raspbian Wheezy (current official images) '/boot/config.txt'-settings: 800MHz, 224MB RAM

[NiLSPACE]

To speed the generation up change in the world.ini marblecaves to wormnestcaves
