i'm writing on a programm which uses the boost date_time library [boost-version = 1.32.0] heavily; while i normally programm in linux using gcc-3.3.5 i also need to compile my program in windows from time to time. because it makes life easier with another library [gtkmm-2.4.8] i'm using mingw-3.4.2; everthing worked fine (my code contains about 10 000 lines using boost_date_time) until i started using a boost::gregorian::year_based_generator. while gcc-3.3.5 in liux accepts my code without even a single warning [with -Wall], mingw-3.4.2 complains - it seems that the compiler has problems with year_based_generator:

Are you able to build the print_holidays example? It uses pointers to year_base_generators.

i'll try that in the next time and post the results of this experiment; be the way, i've now compiled my app in win succesfully by putting evrything which is somehow connected to year_based_generator into #ifndef WIN32_COMPILE .... #endif. that isn't too bad for the moment, because i don't use these methods by now in other parts of my prog [except unit tests]. but sooner or later i will ...

[snip] i've now tried to compile the print_holidays example: this is what i got: $ g++ -lboost_date_time-mgw-1_32 print_holidays.cpp -o test.exe print_holidays.cpp: In function `int main()': print_holidays.cpp:43: error: `year_based_generator' undeclared (first use this function) print_holidays.cpp:43: error: (Each undeclared identifier is reported only once for each function it appears in.) print_holidays.cpp:43: error: template argument 1 is invalid print_holidays.cpp:43: error: template argument 2 is invalid print_holidays.cpp:43: error: invalid type in declaration before ';' token print_holidays.cpp:44: error: `push_back' has not been declared print_holidays.cpp:44: error: request for member of non-aggregate type before '( ' token print_holidays.cpp:45: error: `push_back' has not been declared print_holidays.cpp:45: error: request for member of non-aggregate type before '( ' token print_holidays.cpp:46: error: `push_back' has not been declared print_holidays.cpp:46: error: request for member of non-aggregate type before '( ' token print_holidays.cpp:53: error: `push_back' has not been declared print_holidays.cpp:53: error: request for member of non-aggregate type before '( ' token print_holidays.cpp:55: error: `push_back' has not been declared print_holidays.cpp:55: error: request for member of non-aggregate type before '( ' token print_holidays.cpp:57: error: `push_back' has not been declared print_holidays.cpp:57: error: request for member of non-aggregate type before '( ' token print_holidays.cpp:59: error: `push_back' has not been declared print_holidays.cpp:59: error: request for member of non-aggregate type before '( ' token print_holidays.cpp:64: error: template argument 1 is invalid print_holidays.cpp:64: error: template argument 2 is invalid print_holidays.cpp:64: error: expected `;' before '::' token print_holidays.cpp:65: error: `it' undeclared (first use this function) print_holidays.cpp:65: error: `end' has not been declared print_holidays.cpp:65: error: request for member of non-aggregate type before '( ' token ' token i've also tried to compile some other examples - they work, like the rest of my program; maybe there is something wrong with my installation - but i don't know what. it is also really strange that mingw accepts partial_date [in my app] which is derived from year_based_generator but refuses to work with year_based_generator*. antonio
