Hello,

Could somebody tell me what is wrong with this code (I get a segmentation
fault):
#include "EXTERN.h"
#include "perl.h"
#include "XSUB.h"
#include <stdlib.h>

#include <gsl/gsl_matrix.h>

typedef gsl_matrix* Math__GSL__Matrix__gsl_matrix ;

#include "const-c.inc"

MODULE =3D Test_gsl PACKAGE =3D Test_gsl

double
TOI (WF, size)
Math::GSL::Matrix::gsl_matrix WF
unsigned int size
PREINIT:
double tmp ;
CODE:
printf ("Size %d\n", size) ;
tmp =3D gsl_matrix_get (WF, 0, 0) ;
printf ("%g\n", tmp) ;
RETVAL =3D tmp ;
OUTPUT:
RETVAL


called by:

my $Matr_gsl =3D gsl_matrix_alloc (3, 3) ;
print ref $Matr_gsl, "\n" ;B
Test_gsl::TOI ($Matr_gsl, $size_mat) ;


Thank

i have to say, segment faults, gsl and XS are not what anyone would call
beginners' list topics. there are many other places you can post such
problems and questions.

thanx,

Hi Uri;

Could you be a little more helpful and suggest just one of those many
places to post a more advanced question that is too advanced for this
mailing list? Perhaps perlmonks.org?

Thanks,
Ken Wolcott

you just did one. usenet, other mailing lists (lists.perl.org), web
forums (too many to name), irc (#perl(help) on various nets). the usual
suspects. i can't always name them and they are easy to find.

In addition to what Uri said, there's perl-xs [at] perl.org for XS discussions ,
and there's also Stack Overflow ( http://stackoverflow.com/ ), though I don't
know how many XS experts hang on there (but it is on-topic there).

God considered inflicting XSLT as the tenth plague of Egypt, but then
decided against it because he thought it would be too evil.

perl.xs is another possibility:
