cout << BOOST_PP_STRINGIZE(BOOST_PP_SEQ_ENUM((x)(y)(z)));
That shouldn't work regardless. An invocation of SEQ_ENUM with anything other than one element becomes (what I call) an intermediate. An "intermediate" is an argument to a macro that expands to multiple arguments. There is no way that STRINGIZE could be defined to handle an intermediate. E.g.
#define STRINGIZE(x) PRIMITIVE_STRINGIZE(x) #define PRIMITIVE_STRINGIZE(x) #x
The delay is necessary to allow 'x' to expand on input to STRINGIZE. However, because it does expand in this case, it tries to invoke:
PRIMITIVE_STRINGIZE(x, y, z)
...which is, of course, too many arguments.
What about some extra parenthesis: cout << BOOST_PP_STRINGIZE((BOOST_PP_SEQ_ENUM((x)(y)(z)))); //?
Did you try the other workaround that I sent?
#undef BOOST_PP_SEQ_ENUM #define BOOST_PP_SEQ_ENUM(seq) BOOST_PP_SEQ_ENUM_I((seq)) #define BOOST_PP_SEQ_ENUM_I(arg) BOOST_PP_SEQ_ENUM_II ## arg #define BOOST_PP_SEQ_ENUM_II(seq) \ BOOST_PP_CAT(BOOST_PP_SEQ_ENUM_, BOOST_PP_SEQ_SIZE(seq)) seq \ /**/ It doesn't seem to work with stringize (see above). Outputs: (BOOST_PP_SEQ_ENUM_II((x)(y)(z))) Without stringize everything seems to work fine in the first place... I only care about stringize because it seemed to be a convenient way to debug the stuff... Regards, Arkadiy
