<pre>Hello,

   I've currently compiled the release versions of dune-2.6 and dumux-3.0 using clang 6.0.1 on a FreeBSD-12 host. In order to do this, I've set CMAKE_CXX_COMPILER=clang++, CMAKE_CXX_FLAGS=-stdlib=libc++,  CMAKE_EXE_LINKER_FLAGS='-lpthread -lstdthreads -lc++' .

  But when I try to compile an example program from the dumux templates,  I get 
error: no member named 'bool_constant' in namespace 'std'
  on the instruction (dune/common/std/type_traits.hh:102)
using std::bool_constant

 I'm using the same --opts file used to compile dune, but I must be missing something. 

 I'm going to keep on looking for an answer, but I would appreciate it if someone on this list has any clue.

regards,

Edscott
