From: Wolfgang Bangerth Date: Fri, 13 Feb 2015 04:18:18 +0000 (-0600) Subject: Improve error message when no LAPACK is available. X-Git-Tag: v8.3.0-rc1~473^2 X-Git-Url: https://gitweb.dealii.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=refs%2Fpull%2F532%2Fhead;p=dealii.git Improve error message when no LAPACK is available. The old error message was written when we had ./configure checks for individual LAPACK functions, but this is no longer the case: we get all of LAPACK, or nothing. Reflect this in the text of the error message. --- diff --git a/include/deal.II/lac/lapack_support.h b/include/deal.II/lac/lapack_support.h index 9372af56e9..e3a0e822a5 100644 --- a/include/deal.II/lac/lapack_support.h +++ b/include/deal.II/lac/lapack_support.h @@ -1,6 +1,6 @@ // --------------------------------------------------------------------- // -// Copyright (C) 2005 - 2014 by the deal.II authors +// Copyright (C) 2005 - 2015 by the deal.II authors // // This file is part of the deal.II library. // @@ -142,13 +142,18 @@ namespace LAPACKSupport << state_name(arg1)); /** - * This exception is thrown if a certain function is not implemented in your - * LAPACK version. + * This exception is thrown if a certain LAPACK function is not available + * because no LAPACK installation was detected during configuration. */ DeclException1(ExcMissing, char *, - << "The function " + << "When you ran 'cmake' during installation of deal.II, " + << "no suitable installation of the BLAS or LAPACK library could " + << "be found.
