RaspberryPi?

I've downloaded the RasPi development VM and tried compiling MCServer in it. So far I've run into a problem - ARM doesn't handle va_list as a pointer, but rather a structure. That is in direct contrast with *nix, where the va_list NEEDS to be checked against NULL because on *nix, vsnprintf() fails when passed a NULL va_list.

I got MCServer to compile in the RasPi development VM, but as soon as I run it, it crashes, and I have just no idea on how to debug that. It displays a few lines of the normal log, then some backtrace with no MCServer symbols in it, then a memory map, again not much help, and a note that "core has been dumped". It seems the dev VM doesn't have a RasPi version of gdb. And I couldn't locate the mentioned core file.

This is the output I got:

Have you tried running it using the official debian image? There is a Linux "how-to" on the following page: http://www.cnx-software.com/2012/02/18/r...-emulator/

I've run that on Windows using Qemu 1.0.1 using that "how-to", but never got network working... (It was a bi*** getting the files of the download image but managed in the end by using this tool: http://www.diskinternals.com/linux-reader/)

xoft · 03-30-2012, 01:23 AM

Actually there's an emulator in the dev VM, so I tried that one. That's the one that crashed.

If you have that other image up and running, can you try running MCServer in it? I have no idea on how to provide the binary for you, though, I guess you;ll have to compile yourself. On most *nixes it should be as straightforward as downloading the source and issuing a "make" command. In the dev VM the command was actually "sb2 make" since it was doing cross-compilation.

I have it up and running but have yet to get network working (qemu crashes). Without network I won't be able to d/l get the required packages... I'll let you know if I make any progress...
