Ublas : |
From: Paolo Giarrusso (p.giarrusso_at_[hidden])

I have a program like this:
#include <boost/numeric/ublas/vector_proxy.hpp> // <== (1)
#include <boost/numeric/ublas/lu.hpp>
...
lu_factorize(...)
If I comment out line (1), the call to the lu_factorize template function
fails to compile with the attached errors messages, so in short that
inclusion should be added to lu.hpp.
I also verified in detail the error message before deducing I was missing that
header, so I'm confident, beyond any unreasonable doubt, that is the correct
solution, and that I've hit no C++ pitfall or compiler bug or whatever (I'm
using G++ 4.1, BTW); that's the reason of the excess paranoia with which I've
double-checked everything.
The messages in short are complaining about the lack of functions like:
project(ublas::matrix_column<ublas::matrix<double> >&, ublas::range)
which are declared indeed in <vector_proxy.hpp>. Also, I verified in the
preprocessed source that no two-argument free function overloading project()
exists. So, I definitely think <ublas/lu.hpp> is missing an include (beyond
that, it is also missing some documentation).
Bye, and thanks for your work.
