Linking errors

[J Andres Christen <jac at matmor dot unam dot mx>]

Hi,

I'm traying to use the vector and matrix functions of gsl_0.5 but I
can't link the example program:

#include <stdio.h>
#include <gsl_matrix.h>

int main ()
{
  int i, j; 
  gsl_matrix *m = gsl_matrix_alloc(10, 3);
  
  for (i = 0; i < 10; i++)
    for (j = 0; j < 3; j++)
      gsl_matrix_set (m, i, j, 0.23 + 100*i + j);
  
  for (i = 0; i < 100; i++)
    for (j = 0; j < 3; j++)
      printf("m(%d,%d) = %g\n", i, j, gsl_matrix_get (m, i, j));
}

with

gcc    -I/usr/local/include/gsl -L/usr/local/lib/gsl -O -o sim sim.o
-lgslsys -lgslerr -lgslieeeutils -lgsltest -lutils  -lgslblas
-lgslblascblas -lgslblasnative -lgsleigen -lgsllinalg -lgslrandist
-lgslrng -lgslspecfunc -lgslblock -lgslvector -lgslmatrix -lgsldht
-lgslfft -lgslhistogram -lgslintegration -lgslinterpolation -lgslmin
-lgslmonte -lgslmultiroots -lgslodeiv -lgslpoly -lgslroots -lgslsi


(I've included all the libraries.), I get error messages like:

/usr/local/lib/gsl/libgslmatrix.a(matrix.o): In function 
`gsl_matrix_char_set':
/usr/local/gsl-0.5/matrix/matrix_source.c:26: undefined reference to 
`gsl_check_range'
/usr/local/gsl-0.5/matrix/matrix_source.c:30: undefined reference to 
`gsl_error'/usr/local/gsl-0.5/matrix/matrix_source.c:34: undefined
reference to `gsl_error'



What am I doing wrong?


How could I know what libraries to use?  It is not clear to me from
reading the manual.



Thanks,
Andrés.
