[Lapackpp-devel] Problem using lapackpp & an optimization package

[Sonia S. <son...@gm...>]

Hi,

I am doing development in Microsoft Visual Studio 2003. I have been using
lapackpp-2.5.0 for solving linear system of equations and doing SVD.
Recently I started using an open source optimization package IPOpt to solve
an optimization problem. This library uses certain routines in BLAS, LAPACK,
HSL.

The problem is that my code crashes in the lapackpp's call to LaSVD_IP(). It
crashes giving a "floating point underflow" error. This doesnt happen if I
remove ipopt's libs and code. I havnt really written any code for calling
this optimization library, just instantiated its class just to see link the
ipopt infrastructure into my existing code. I have used IPOpt earlier but
then wasnt using lapackpp and ipopt worked fine. I have posted this question
on the ipopt forum too. I am posting here too just in case anyone has any
idea of what the problem could be.

Thanks,
