hello all: I have the following code: #define REGISTER_MODULE(module)(\ #ifdef BOOST_PP_EQUAL(BOOST_PP_LIST_**SIZE(MODULES), 0)\ //there are currently no modules in the list. #define MODULES((module), BOOST_PP_NIL) #else BOOST_PP_LIST_APPEND(MODULES, module)\ #endif )
I am somewhat of a newb at preprocessor magic, so any advice would be useful. For whatever reason this translates out to 'module)' when I try to compile it with -E -P. The idea is that it will add to the modules list (assuming the modules list exists) the module to be registered, which should just be a type. Thanks,
Someone can correct me here, but I believe you can't use preprocessor directives (#define, #if, etc.) within a macro definition, and, well, who knows what'll happen if you try :/ - Jeff
