    Compling errors

    Hello, here is my code below... I'm getting compiling errors as below. What is wrong?

    Code:
    cc1: warnings being treated as errors
    q1.c: In function 'GRAPHinit':
    q1.c:49: error: implicit declaration of function 'MATRIXint'
    q1.c:49: error: assignment makes pointer from integer without a cast
    Code:
    #include <stdio.h>
    #include <stdlib.h>
    
    #define maxV 10
    
    int visited[maxV];
    
    typedef struct { int v; int w; } Edge;
    struct graph { int V; int E; int **adj; }; // adj [][] is a matrix.
    typedef struct graph *Graph;
    
    Graph GRAPHinit(int V);
    int **MATRIXinit(int r, int c, int val);
    int GRAPHpath(Graph G, int v, int w);
    int pathR(Graph G, int v, int w);
    
    int main(int argc, char *argv[]) {
    
    
    
       return 0;
    }
    
    int GRAPHpath(Graph G, int v, int w) {
       int t;
    
       for (t = 0; t < G -> V; t++) visited[t] = 0;
    
       return pathR(G, v, w);
    }
    
    int pathR(Graph G, int v, int w) {
       int t;
    
       if (v == w) return 1;
    
       visited[v] = 1;
    
       for (t = 0; t < G ->V; t++)
          if (G ->adj[v][t] == 1)
             if (visited[t] == 0)
                if (pathR(G, t, w)) return 1;
       return 0; //We will not come back to v. So, we will leave v as visited.
    }
    
    Graph GRAPHinit(int V) {
       Graph G = malloc(sizeof *G);
       G ->V = V; G->E = 0;
       G->adj = MATRIXint(V, V, 0);
       return G;
    }
    
    int **MATRIXinit(int r, int c, int val){
       int i, j;
       int **t = malloc( r * sizeof(int *) );
       for (i = 0; i < r; i++)
          t[i] = malloc(c * sizeof(int));
       for (i = 0; i < r; i++)
          for (j = 0; j < c; j++)
             t[i][j] = val;
       return t;
    }
    Thanks
