Hi Ovanes,
I need to define a map with int_<1...150>->Type1...150 pairs.
Im source file I define:
#define BOOST_MPL_CFG_NO_PREPROCESSED_HEADERS #define BOOST_MPL_LIMIT_MAP_SIZE 150
#include
A word of caution: redefining BOOST_MPL_LIMIT_MAP_SIZE is not recommended. Doing so globally will make you pay for what you probably don't use (unless all present and future 'map' usages in your project demand the 150-elements limit), and doing so within a translation unit will lead to an ODR violation. If you need to construct a sequence beyond the default size, use its numbered form (http://www.boost.org/libs/mpl/doc/refmanual/variadic-sequence.html).
When compiling I get an error in the file: ...\boost\include\boost-1_33_1\boost\mpl\map.hpp on line: 36 fatal error C1083: Cannot open include file: 'boost/mpl/map/map150.hpp': No such file or directory
Development environment is Visual C++ 8 Express Edition
The help states: BOOST_MPL_CFG_NO_PREPROCESSED_HEADERS is an boolean configuration macro regulating library's internal use of preprocessed headers. When defined, it instructs the MPL to discard the pre-generated headers found in boost/mpl/aux_/preprocessed directory and use preprocessor metaprogramming techniques to generate the necessary versions of the library components on the fly.
In this implementation of the library, the macro is not defined by default. To change the default configuration, define BOOST_MPL_CFG_NO_PREPROCESSED_HEADERS before including any library header.
Note that the text above does _not_ say that discarding the the pre-generated headers -- Aleksey Gurtovoy MetaCommunications Engineering
