We could condition compilation in itkFEMLinearSystemWrapperVNL.cxx using the preprocessor directives found in core/vxl_version.h<br><br><br><div class="gmail_quote">On Fri, Jul 2, 2010 at 6:13 PM, Bill Lorensen <span dir="ltr"><<a href="mailto:bill.lorensen@gmail.com">bill.lorensen@gmail.com</a>></span> wrote:<br>
<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">VXL made a non-backward compatible change to the API of vnl_sparse_matrix.<br>
<br>
One of the vxl developers sent the folloing reply to a similar recent question:<br>
<br>
You'll either have to update line 265 of<br>
ITK/Code/Numerics/FEM/itkFEMLinearSystemWrapperVNL.cxx<br>
to use the operator*() method of vnl_sparse_matrix<T>,<br>
or make the mult() method of vnl_sparse_matrix<T> public again in your<br>
copy of vxl.<br>
<br>
Methods mult(), add() and subtract() of vnl_sparse_matrix<T> will<br>
revert to "public" in the next vxl release, be it with a deprecation<br>
warning.<br>
