Hi,
I decided to try Phoenix3. I looked up at a couple of examples and
since I use Boost.Units (which depends on Boost.MPL) heavily I tried
to mix both only to find out that there is an obscure incompatibility
between MPL and Phoenix3. The way to show this is just to compile the
phoenix3/.../function.cpp example
https://svn.boost.org/svn/boost/sandbox/SOC/2010/phoenix3/libs/phoenix/examp...
with the following added line:
#include
I get this error message:
In file included from function.cpp:12:
/home/user/usr/include/boost/mpl/multiplies.hpp:38: error: wrong
number of template arguments (7, should be 5)
/home/user/usr/include/boost/mpl/aux_/preprocessed/gcc/times.hpp:68:
error: provided for ‘template struct boost::mpl::times’
The full code (almost identical to the example) follows -- Thank
you, Alfredo
