I hesitate to mark this as [Polygon] because the error message is in a different part of Boost. However, I have little idea what the actual cause of the problem is or what any of the relevant stuff even means, so I figure [Polygon] is as good as anything at the moment...
As before, this is a custom version of CodeWarrior an embedded ARM system, so I have no idea how well it corresponds with other versions of CodeWarrior.
Please try polygon in standalone mode and define the BOOST_POLYGON_NO_DEPS macro. In order to use mpl and and or for SFINAE I had to pull in quite a lot of the mpl. My own implementation of these is enabled by the macro and if you see a compiler error with them I'll quickly be able to understand the problem. If you don't see a compiler error with the macro then I can come up with a new macro to exclude mpl dependency but still use enable_if and config.hpp.
Here is a trivial program that illustrates the problem, using the BOOST_VERY_LITTLE_SFINAE patch from the last discussion here:
#include <iostream> #define BOOST_VERY_LITTLE_SFINAE #define BOOST_POLYGON_NO_DEPS #include <boost/polygon/polygon.hpp>
using namespace boost::polygon; using namespace boost::polygon::operators;
int main() { polygon_set_data<int> ps; ps += rectangle_data<int>(0, 0, 1, 1); return 0; }
This results in the following error message :
Error : illegal use of template argument dependent type 'T::type'
The error occurs in this part of boost/mpl/aux_/preprocessed/plain/and.hpp:
template< typename T1, typename T2, typename T3, typename T4 > struct and_impl< true,T1,T2,T3,T4 > : and_impl< BOOST_MPL_AUX_NESTED_TYPE_WKND(T1)::value , T2, T3, T4 , true_ > { };
Any ideas about what's wrong or how to fix it?
