Ublas : |

Hi All,
I'm having some trouble using the ublas bindings. Please forgive my
ignorance, I have not found any step-by-step documentation.
So I downloaded the bindings from:
http://news.tiker.net/software/boost-bindings
In cygwin, I copied the bindings into the numeric folder, and copied
'configure' and 'makefile.in' to C:\Program Files\boost\boost_1_34_0
directory and entered:
./configure
make --debug
It makes fine, but notes that:
File 'all' does not exist.
Must remake target 'all'.
I definitely am doing something wrong, as I get as error ("failed to
specialize function template 'matrix_traits<M>::pointer") when I call the
bindings. I have MKL installed/linked properly, and have been working with
uBlas for a while. I'm sorry to bother everyone with such a basic question,
but I'm unsure of how to proceed.
Thanks in advance,
Ian
