I think I am going to use mpfr (mpreal C++ interface) and mpcomplex. I needed to reorder the libraries, -lmpc before -lmpfr as a test case was not linking properly. I had copied MPFRLIBS in the examples/mlapack Makefile. thanks for your comment. Could you please tell me which part of MPACK is wrong? > There does not seem to be an operator<< in mcomplex but it should not be much work for me to make one. Could you please tell me what "operator <<" do for mpcomplex? > I am using gfortran, so plan to follow the MAGMA style to make an interface, but I will start with some C++ examples with MPACK to get a better understanding. I am more familiar with LAPACK than MPFR. ok. Please let me know when idea comes up. Gfortran interface is also very important. > You will find I am quite active at the moment on the MAGMA forum. > > Are you in touch with Goto Kazusige? There is unfortunately a bug of some sort in the Nehalem version of GotoBlas2 which means that safe operation requires use of the 4 core version even on an 8 core machine. It does not look as though maintenance is being done any more on the distribution site. > > I don't have full details but can get them if needed.

The problem is that I want to adapt some code which is in FORTRAN so I am going to have to find some way to interface the two. I am working with MAGMA (LAPACK for GPGPUs see http://icl.cs.utk.edu/magma/index.html) and I have to interface FORTRAN to C++ there. >> >> Thank you >> >> John >> >> Dr John P.
