[GRASS-dev] compilation error - macro _n()

[Martin Landa]

Hi all,

recently I got problem compiling GRASS module against CGAL library.
The source of problem is duplicated definition of _n() macro.

In file included from /usr/include/boost/random.hpp:37:0,
                 from /usr/local/include/CGAL/spatial_sort.h:31,
                 from /usr/local/include/CGAL/Triangulation_3.h:47,
                 from local_proto.h:4,
                 from main.cpp:25:
/usr/include/boost/random/discard_block.hpp:60:42: error: macro "_n"
requires 3 arguments, but only 1 given
     discard_block_engine() : _rng(), _n(0) { }

GRASS defines _n() macro as [1], Boost is using _n() macro in different meaning.
Any idea who to fix this problem correctly?

Martin
