I'm sure this is an easy answer and I'm just doing something dumb, but I'm trying to get my code to compile and it seems any user code doesn't work, I keep getting these "dangerous relocation: call0: call target out of range: ..." errors. Any idea what I'm doing wrong?

P.S. I did have to modify eagle.app.v6.ld to include __stack.

Any help would be appreciated greatly.

Try adding -mlongcalls to your compiler options.
xtensa ISA cannot encode direct calls longer than 512K from the call site. When -mlongcalls is passed to compiler (to assembler, actually) it will replace direct calls with a sequence of 'load target address into a register and call by address in register'. At linking step such expanded calls may be collapsed back to one instruction if linker sees that callee is in the range of a direct call.
EDIT:
Though it seems that there's not that much memory to overflow direct call range. Must be something in your linker script.

YAY! I have a .elf... of my Minecraft server. Hopefully I'll test it tomorrow. Thank you! Now, when someone else googles that error, they will have a solution!

Oops, forgot to post the first part to my linker script.
