My code compiles on visual studio 8, but on g++ 3.3.2 (linux) and with g++ 3.4.4 (cygwin) it chokes with the following error:

In function `void convertToScctsOpt()': optionmanager.cpp:119: error: expected init-declarator before "ScctsType" optionmanager.cpp:119: error: expected `, ' or `;' before "ScctsType" optionmanager.cpp:120: error: `ScctsType' undeclared (first use this function)

Is some special command line argument needed?

No.

#define BOOST_MPL_CFG_NO_PREPROCESSED_HEADERS #define BOOST_MPL_LIMIT_MAP_SIZE 50 #include <boost/mpl/map.hpp> #include <boost/mpl/at.hpp> #include <boost/mpl/pair.hpp> namespace bm = boost::mpl;

typedef bm::map< bm::pair<Type1, MappedType1>, . . . bm::pair<Type41, MappedType41>

...

TypeToTypeMap;

template<typename SoapType> inline void convertToScctsOpt() { typedef bm::at<TypeToTypeMap,SoapType>::type ScctsType;

}

This last function needs to be: template<typename SoapType> inline void convertToScctsOpt() { typedef typename bm::at<TypeToTypeMap,SoapType>::type ScctsType; } The "typename" keyword is required here by the C++ standard to indicate that ::type is a nested type.
