To boost users: Greetings! I do not know if this the correct format but here are the issues that I am running into: /boost/numeric/bindings/lapack/detail/ The file clapack.h includes itself causing an error /boost/numeric/bindings/blas/detail/ The file cblas.h includes itself causing an error I changed them to lapack.h and blas.h respectively but I got several errors. I checked out the latest version of numeric bindings from boost.svn this morning. I am using Microsoft Visual Studio 2008 without a Fortran compiler (I need to use clapack) The issues here are that the l lapack routines come with 2 underscores, i.e. _sgesvd_ instead of sgesvd_ I declared BOOST_NUMERIC_BINDINGS_USE_CLAPACK in my driver. Thank you very much in advance for your assistance. Simon N. Mpasi
