Full server experience on Raspberry pi?

[nasomi]

I think you will run into some issues with cpu usage as well. My backup server is a single xeon 5130 dual core, and with 60 players online it's using 90% cpu and 500mb ram.

Has anyone made any progress on compiling in ARM? I'm considering getting a raspberry pi 2 to use for the game server if I can free up time to start trying to compile the code. DSsearch will compile on a RPi model B as well as manage a decent MYSQL database. If I can get the ZMQ library issue on DSConnect resolved I can try to further compile that for the model B as well. I have a feeling DSGame will take me a while longer to work through if at all. I mostly want the game for nostalgic reasons, So I can leave a character somewhere and put the monitor on the wall to be a window into a world I once walked with friends and family. Anyone have an opinion on if it's worth trying to port?


Raspi 2 quard core Armv7 @ 900Mhz (can be overlocked if needed) will run ubuntu 10.04, 1 GB RAM

ALso: can anyone suggest a good post about starting working on some of the unimplemented aspects of the game? chocobo raising would be my main interest.

my current server has the model B running my SQL database and the apps running in an Ubuntu VM on my old mac mini... I need to build a signature someday...

I've made a bit of progress getting this to run on the Pi. Based on the comments in this thread, I may be at a dead end though..

I'm using a distro for the Raspberry Pi 2 meant for emulating old game consoles called RetroPie. I have it fully overclocked and haven't had any issues playing ps1 or n64 emulators. RetroPie is Debian based, so I figured I'd have a shot at it working. It took me a while to figure out how to get gcc 4.9 etc. installed, but once I got around that, I was met with the following error:

That goes well beyond my ability to troubleshoot on my own, and the Googles are not helping. So here I am, hoping someone can help. It'd be pretty neat to have a handheld game system that doubles as a FFXI server.

that just means the version of ZMQ you got is not the right version - I think you need 3 and have 1 (or the other way around..)

either way, if you can't get the right one with your package manager you can compile it yourself

[Totien]

Well, that made a bit more progress. I think I still have the wrong version of zmq though. I found here the proper command to get zmq, but I can't seem to download 3.2 and I'm not experienced enough to compile from source on my own. A brief step-by-step would be immensely appreciated.

In order to download the 3.2 version, I have to change jessie to wheezy in /etc/apt/sources.list, then apt-get update. If I do that though, no package is found. Leaving /etc/apt/sources.list set to jessie will work, but it downloads version 4.0 which is giving me different errors.

[kjLotus]

don't be scared of compiling it yourself, you have to learn those things if you are using unix

[Totien]

Alrighty. I fucked up my entire distro and had to redo the image, but I'm caught back up on the DS emulator, and I'll worry about the retro games later.

So I found and compiled from source zmq 3.2.2, then I had to cp zmq.cpp /usr/include as I found here.

I've now compiled and installed zmq 3.2.2, 3.2.3, and 3.2.4, and all are failing with the following error:

okay, this is 100% my bad, sorry:

apparently the package "libzmq3" is zmq 4.0.4 (at least according to my zmq.h), and it does also require the cpp binding (which should come with libzmq3-dev)

[Totien]

Ok, I'll give it a shot in the morning. I'm pretty sure the /use/include/zmq.hpp file from my previous post will take care of the cpp binding.

I took a look at the makefile, and I am nowhere near done compiling so here's hoping this is the last issue I'll have. All the other requirements to build went in place without a problem. I had to get two extra packages to run add-apt-repository though. software-properties-common and python-software-properties iirc. Other than that, zmq has been the only trouble I've had.
