Program in c++ won't compile in linux

Hi guys!
My question is a bit strange because I don't know anything of programming. There's a program that plays chess and a variant of it (called crazyhouse) whose code is open source. I tried to compile it under linux but it did not work.
Here is the message I get when I type "make" in the terminal:

g++ -Wall -g -O1 -DNDEBUG -c aimoves.cpp -o aimoves.o
In file included from aimoves.cpp:19:0:
board.h:740:21: error: extra qualification ‘boardStruct::’ on member ‘getColorOnMove’ [-fpermissive]
board.h:754:21: error: extra qualification ‘boardStruct::’ on member ‘getColorOffMove’ [-fpermissive]
In file included from brain.h:20:0,
                 from aimoves.cpp:20:
interface.h:33:14: error: expected initializer before ‘output’
make: *** [aimoves.o] Error 1

.
In a chess server, I asked a programmer if he could have a look at the code, he said that the code is very archaic and that he could fix the problem after a tweak in the Makefile. But he didn't want to share his code, so I am left at the beginning.
I have posted the full code in github at https://github.com/arbolis/Sunsetter-crazyhouse.
Since I have no idea about programming, I really don't know what tweaks I have to do in the Makefile for the program to compile. I'd appreciate if someone you fix the problem. So I can update the code in github and the program will compile for everyone interested in it.
For those who don't feel like going to github for some reason, here's the makefile:

# Makefile to build sunsetter for linux.
#
# -Wall turns on full compiler warnings, only of interest to developers
# -O1 turns on optimization at a moderate level.
# -O3 turns on optimization at the highest level. (confuses the debugger though)
# -g turns on debugging data in the executable.
# -DNDEBUG turns off assert() debugging in the code
#
# CFLAGS for a "release" built, no debugging and highly optimized.
# CFLAGS = -O3 -DNDEBUG
#
# uncomment this line to build a debug version.
# need to type "make clean;make" to get the full effect
# CFLAGS = -Wall -g -O1 -DDEBUG
#
# or this one for a "light debug" version which works well with gdb
# but is otherwise like the release version.
CFLAGS = -Wall -g -O1 -DNDEBUG
#
# set of flags that produces the best speed on Angrim's
# Athlon Thunderbird with gcc version egcs-2.91.66
# CFLAGS = -O3 -march=i486 -DNDEBUG

# sunsetter is the default target, so either "make" or "make sunsetter" will do

Thank you very much in advance for any help.
