Hi, I'm getting the following error when I compile kmeansTest.c

mpi$ mpicc -o kmeansTest kmeansTest.c -lm

kmeansTest.c: In function ‘main’:
kmeansTest.c:274:3: warning: implicit declaration of function ‘kmeans_process’ [-Wimplicit-function-declaration]
kmeans_process(&p_data, &clusters, newCentroids, &new_SumOfDist);
