cannot pass arguments to gcc

i am fresh in gcc programming and i want to compile a .c file with my compiler. but i dont know how? in this case my "main" part starts this like:

int main(int argc, char *argv[]){

int i,j,k;

int epsilon,bestepsilon;

float soundness=0,bestsoundness=0;

if (argc!=3) {

    printf("[usage] : %s <datasetname> <bestepsilon> \n", argv[0]);

    exit(1);

}

readPoints(argv[1]);

readDatainfo(argv[1]);
if (bestepsilon==0) {

for(epsilon=INITIALEPSILON; epsilon<=FINALEPSILON; epsilon++) { ...

but "INITIALEPSILON" and "FINALEPSILON" are not defines in this program and i should pass them from other file.

some body help me please.

i have a "makefile" that is as below:

DEFINE1=-DMINDIM=2 -DMAXDIM=20 -DMEANDIM=10 -DNCLUSTER=5 -DNPOINTS=100000 -DMINSIZE=5000
DEFINE2=-DFOUTLIER=0.1 -DSPREADPARAM=2 -DSCALEMAX=2 -DNSHARE=2 
com.o:../src/com.c
$(CC) -c ../src/com.c
linpack.o:../src/linpack.c
$(CC) -c ../src/linpack.c
randlib.o:../src/randlib.c
$(CC) -c ../src/randlib.c
gendata:gendata.c ../src/com.o ../src/linpack.o ../src/randlib.o
$(CC) $(DEFINE1) $(DEFINE2) -g -o gendata gendata.c ../src/com.o ../src/linpack.o ../src/randlib.o -lm

this make gendata that generate data set.

after that i need the findit.c that i describe it above. iwant to pass parameters like mindim from makefile to findit to compile.

As already mentioned by @Jonathan Leffler 

#include <string.h>
#include <stdio.h>

int  main(int argc, char *argv[])
{
   printf("%d   %d\n",INITIALEPSILON,FINALEPSILON);
}

compile

$ gcc -DINITIALEPSILON=100 -DFINALEPSILON=500 test.c -o test

run

$ ./test
100 500
