make server fails

[vladfi1]

On ubuntu 15.10. The compilation appears to go smoothly but I get a ton of linking errors:

lmao that commit fixed another issue, not this one. my bad!

h4ck4th0n/server.cpp

this looks like an older version of the repo; can you pull and try again? (compiling an older version should work, but it's not a concern now since we've probably refactored the code)

all of the sources should be under a src/ directory.

edit: wait, all the compile steps look right. why is it still looking at h4ck4th0n/server.cpp? could the old stuff not have been deleted properly?

[shewu]

lingering server.o from the bronze age when all source files were in the top level directory confused the compile system. removing that file resolved this issue. closing.
