Hi everyone
I just ran into quite a problem. I checked out the latest cvs version of
the boost-sandbox to try the bindings for lapack.
I tried list little sample program - just to get something working
(compilation):
--------
#include <iostream>
#include <boost/numeric/bindings/lapack/gesv.hpp>
#include <boost/numeric/ublas/matrix.hpp>
namespace ublas = boost::numeric::ublas;
namespace lapack = boost::numeric::bindings::lapack;
int main() {
ublas::matrix<double, ublas::column_major> A(3,3), B(3,1);
lapack::gesv(A,B);
return 0;
}
--------
As far as the examples I've seen the boost bindings for lapack should do
this without trouble since the matrix is column major.
But compilation (with stl-filt and gcc 3.4.6) gives me this error:

It seems to me that the size1 and size2 isn't a member function? What
the * is wrong here?
I'm using the 1.33.1 version of boost (just from the gentoo ebuild).
Thanks for helping!
