[Dune] Error building dune-istl: #if with no expression

[Lars Vingli Odsæter]

Hello.

I am working on the OPM Project, which depends on dune-istl. I have successfully built dune-common, but when I try to build dune-istl (with dunecontrol all) I get the following error message:

In file included from ../../../dune/istl/gsetc.hh:11,
                 from example.cc:23:
../../../dune/istl/multitypeblockvector.hh:4:15: error: #if with no expression
In file included from ../../../dune/istl/gsetc.hh:12,
                 from example.cc:23:
../../../dune/istl/multitypeblockmatrix.hh:9:15: error: #if with no expression
In file included from example.cc:23:
../../../dune/istl/gsetc.hh:376:15: error: #if with no expression
../../../dune/istl/gsetc.hh:424:15: error: #if with no expression
../../../dune/istl/gsetc.hh:474:15: error: #if with no expression
../../../dune/istl/gsetc.hh:524:15: error: #if with no expression

I opened multitypeblockvector.hh and identified what caused the error. On line 9 it says
   #if HAVE_BOOST

Next, I opened dune-istl/config.h and observed that HAVE_BOOST and HAVE_BOOST_FUSION was defined as
#define HAVE_BOOST
#define HAVE_BOOST_FUSION

I tried to edit it to:
#define HAVE_BOOST 1
#define HAVE_BOOST_FUSION 1

This was based on my experience and help from google that an undefined macro may cause this error. Then I called dunecontrol make on dune-istl, and now it worked!

So what goes wrong here? I suppose it is not intended that I should edit config.h, but that this should work automatically. Please ask for more information if necessary. I have all boost-libraries installed, and they are detected by the building process.
