DUNE-library ============ DUNE, the Distributed and Unified Numerics Environment is a modular toolbox for solving partial differential equations with grid-based methods. The main intention is to create slim interfaces allowing an efficient use of legacy and/or new libraries. Using C++ techniques DUNE allows to use very different implementation of the same concept (i.e. grid, solver, ...) under a common interface with a very low overhead. DUNE was designed with flexibility in mind. It supports easy discretization using methods, like Finite Elements, Finite Volume and also Finite Differences. Through separation of data structures DUNE allows fast Linear Algebra like provided in the ISTL module, or usage of external libraries like blas. This package contains the basic DUNE common classes. Dependencies ------------ dune-common depends on the following software packages - pkg-config - GNU C, C++ >=4.4 these might also work: icc (C/C++) >= 13.0 Clang >= 3.2 The following software is recommend but optional: - MPI (either OpenMPI, lam, or mpich suffice) For a full explanation of the DUNE installation process please read the installation notes [0]. The following introduction is meant for the impatient. License ------- The DUNE-library and headers are licensed under version 2 of the GNU General Public License, with the so-called "runtime exception", as follows: As a special exception, you may use the DUNE source files as part of a software library or application without restriction. Specifically, if other files instantiate templates or use macros or inline functions from one or more of the DUNE source files, or you compile one or more of the DUNE source files and link them with other files to produce an executable, this does not by itself cause the resulting executable to be covered by the GNU General Public License. This exception does not however invalidate any other reasons why the executable file might be covered by the GNU General Public License. This licence clones the one of the libstc++ library. For further implications of this library please see their licence page [3] See the file COPYING for full copying permissions. Installation ------------ Short installation instructions can be found in file INSTALL. For the full instructions please see [0].

These check whether std::call_once() works and provide a helpful error message if it does not. They should be used in any code that uses std::call_once(). Call once may not work if one forgets to _link_ with -pthread (or similar options). The nasty think about this is that linking still succeeds, so this can only be detected at run time. We cannot (in general) run compiled programs during configure, since we may be cross-compiling, so whatever we get from configure is at best a guess. Even if configure detects the necessary flags correctly, there may still be errors in the build system such that the executable is linked without them. The reason to provide such a facility is that the bug is quite difficult to debug when it appears. The error message is mangled due to a different bug, and is quite unhelpful anyway. And then there is the fun with weak symbols...
