I tried using the full namespace path, but my compiler keeps on complaining about it, with the following error message:

error C2039: 'copy' : is not a member of 'boost::numeric::bindings::blas'

It seems that 'copy' is not defined in the namespace boost::numeric::bindings::blas (I don't get this error when using boost::numeric::bindings::atlas).

Thanks!

Fran

Subject: Re: [ublas] Missing "copy" in BLAS bindings?

Looking at the error message, I have the impression the compiler tries
to use std::copy.

Please try using the full namespace path in the copy function. This will
remove the ambiguity in the symbol copy.
