Hello.
I'm trying to use a "Numerical Recipes in C" routine for the first time.

I got a file with the main function, main.c, and a file with the routine I wanna use (Jacobi function) jacobi.c.
In addition, I have 2 header files, that, for what I could see, are standard for all Numerical Recipes routines: nrutil.h and nr.h.

Here the are the codes:

main.c:
[CODE]#include
#include "nr.h"
#include "nrutil.h"

int main(void)
{
int i, j, nrot;

int n = 2;
/*
We need a Numerical Recipes-style "matrix" to use
as an argument to call the jacobi function.
Here are the matrix values stored in row-major
order in a 1-D array. This array name will be used
as an argument for the convert_matrix function.
*/
float a_array[] = {
5.0, -2.0, /* First row */
-2.0, 2.0 /* Second row */
};

float *d = vector(1, n);
float *r = vector(1, n);
float **v = matrix(1, n, 1, n);
float **a = convert_matrix(&a_array[0], 1, n, 1, n);

printf("Matrix:
");
for (i = 1; i <= n; i++) {
for (j = 1; j <= n; j++) {
printf(" %+13.6e", a[i][j]);
}
printf("
");
}
printf("
");

jacobi(a, n, d, v, &nrot);

printf("Eigenvalues:
");
for (i = 1; i <= n; i++) {
printf(" Number %d:%+14.6e
", i, d[i]);
}
printf("
");

printf("Eigenvectors:
");
for (i = 1; i <= n; i++) {
printf(" Number %d:", i);
for (j = 1; j <= n; j++) {
printf("%+14.6e", v[j][i]);
}
printf("
");
}
printf("
");

printf("Number of Jacobi rotations = %d
", nrot);

free_convert_matrix(a, 1, n, 1, n);
free_matrix(v, 1, n, 1, n);
free_vector(r, 1, n);
free_vector(d, 1, n);

When I try to compile it (I use gcc 4.6 on Ubuntu) using the command "gcc -Wall -o jacobi.exe main.c jacobi.c", I get the following errors :

I was warned that it could be a linker problem. If it is the problem, how can I proceed?

I'm sorry if I'm commiting a rookie mistake.
mvww.
