Issues in irace

attempted to compile ACOTSP-1.03 using make, but encountered multiple definition errors during linking. The errors indicate that the variables n and distance are defined in multiple object files (acotsp.o, TSP.o, utilities.o, ants.o, InOut.o, ls.o).

jyoti@jyoti:/tuning/ACOTSP-1.03$ cd
jyoti@jyoti:$ cd ./tuning/ACOTSP-1.03
jyoti@jyoti:~/tuning/ACOTSP-1.03$ make
cc acotsp.o TSP.o utilities.o ants.o InOut.o dos_timer.o ls.o parse.o -lm -o acotsp
/usr/bin/ld: TSP.o:(.bss+0x238): multiple definition of n'; acotsp.o:(.bss+0x8): first defined here /usr/bin/ld: TSP.o:(.bss+0x230): multiple definition of distance'; acotsp.o:(.bss+0x0): first defined here

collect2: error: ld returned 1 exit status
make: *** [: acotsp] Error 1

since make fails, the acotsp executable is not generated, preventing me from running it.
