All of the output you posted were warnings, not errors. Unless you got some explicit errors during the compile process, the binaries should have been produced. Though they probably should be fixed, I believe that the code still works (to the extent that 0.3.1 works since there were a few bugs that will hopefully be gone in 0.3.2
). I personally get the same warnings when compiling world (and I assume zone; I don't feel like recompiling it just to find out, but I seem to remember a lot more warnings in zone than in world), so don't worry about it.
If you go and look at line 1945, you'll see this:
npc_type_array[atoi(row[0])]->fixedZ = atof(row[21]);
It looks like fixedZ is defined in zone/mob.h (line 265) to be an int16. It looks like the atof call should be an atoi or fixedZ should be defined as a double/float. Since I don't know what fixedZ defines, I don't know if it should be integral or floating point. I guess minimally, there should be an explicit cast there. But that's why this is version 0.3.1 and not 1.0
I don't know what the other warning is all about though. It could be related (caused by) the first one, or it could be another problem in the line that I don't immediately see...
