Looking for hints from anyone using LAPACK with clisp (2.48). I've built the clocc software, and build and loaded f2cl, then compiled and loaded LAPACK. When I call an LAPACK function, say by calling (test-dgeev) in the lapack-tests.lisp file, there is a floating-point underflow or divide by zero failure. But it is not the input data. I have a build of maxima built on top of clisp (2.41), and calling the same function with the same data (within the to_lisp() environment) is successful. Evidently, there is a step needed in the f2cl usage which the maxima developers have figured out. |

I think Raymond Toy, the f2cl maintainer, might be able to help you. > * Al Steffens <ncf...@ar...g> [2012-03-25 15:52:30 +0000]: > > Looking for hints from anyone using LAPACK with clisp (2.48).
