MPL map / multi index dependency bug
The following code does not compile using gcc 3.4.3. I tried it with the
same results using 1.32 and 1.33. Reversing the order of the #includes
fixes the problem.
Is this a known order dependency? If so, I couldn't find it documented
anywhere.
#include

I've reproduced your problem with GCC 3.2, though the error messages are
slightly different. Digging a little deeper, the issue can be reproduced with
this
MPL-only snippet:

#include
/* include last to suppress compiler error */ #include int main() { return 0; }
Is this also failing for your compiler version? I'm posting this in a separate thread as it seems to be a MPL-specific problem.

Yes, that also fails for me using gcc 3.4.3, with this error output: In file included from /usr/local/include/boost-1_32/boost/mpl/map/map0.hpp:18, from /usr/local/include/boost-1_32/boost/mpl/map/map10.hpp:19, from /usr/local/include/boost-1_32/boost/mpl/map/map20.hpp:19, from /usr/local/include/boost-1_32/boost/mpl/map.hpp:36, from temp.cpp:3: /usr/local/include/boost-1_32/boost/mpl/map/aux_/contains_impl.hpp:31: error: no type named `apply' in `struct boost::mpl::at_implboost::mpl::aux::map_tag' /usr/local/include/boost-1_32/boost/mpl/map/aux_/contains_impl.hpp:31: error: no type named `apply' in `struct boost::mpl::at_implboost::mpl::aux::map_tag' /usr/local/include/boost-1_32/boost/mpl/map/aux_/contains_impl.hpp:34: error: template argument 1 is invalid /usr/local/include/boost-1_32/boost/mpl/map/aux_/contains_impl.hpp:34: error: expected `{' before '::' token /usr/local/include/boost-1_32/boost/mpl/map/aux_/contains_impl.hpp:35: error: invalid type in declaration before ',' token /usr/local/include/boost-1_32/boost/mpl/map/aux_/contains_impl.hpp:35: error: invalid use of `::' /usr/local/include/boost-1_32/boost/mpl/map/aux_/contains_impl.hpp:35: error: expected `;' before ',' token /usr/local/include/boost-1_32/boost/mpl/map/aux_/contains_impl.hpp:38: error: data member `type' cannot be a member template In file included from /usr/local/include/boost-1_32/boost/mpl/map/aux_/erase_key_impl.hpp:19, from /usr/local/include/boost-1_32/boost/mpl/map/aux_/erase_impl.hpp:19, from /usr/local/include/boost-1_32/boost/mpl/map/map0.hpp:22, from /usr/local/include/boost-1_32/boost/mpl/map/map10.hpp:19, from /usr/local/include/boost-1_32/boost/mpl/map/map20.hpp:19, from /usr/local/include/boost-1_32/boost/mpl/map.hpp:36, from temp.cpp:3: /usr/local/include/boost-1_32/boost/mpl/map/aux_/has_key_impl.hpp:33: error: no type named `apply' in `struct boost::mpl::at_implboost::mpl::aux::map_tag' /usr/local/include/boost-1_32/boost/mpl/map/aux_/has_key_impl.hpp:33: error: no type named `apply' in `struct boost::mpl::at_implboost::mpl::aux::map_tag' /usr/local/include/boost-1_32/boost/mpl/map/aux_/has_key_impl.hpp:33: error: wrong number of template arguments (2, should be 1) /usr/local/include/boost-1_32/boost/mpl/void.hpp:55: error: provided for `template<class T> struct boost::mpl::is_not_void_' /usr/local/include/boost-1_32/boost/mpl/map/aux_/has_key_impl.hpp:33: error: expected `{' before '::' token /usr/local/include/boost-1_32/boost/mpl/map/aux_/has_key_impl.hpp:34: error: expected init-declarator before '>' token /usr/local/include/boost-1_32/boost/mpl/map/aux_/has_key_impl.hpp:34: error: expected `;' before '>' token In file included from /usr/local/include/boost-1_32/boost/mpl/map/aux_/begin_end_impl.hpp:20, from /usr/local/include/boost-1_32/boost/mpl/map/map0.hpp:30, from /usr/local/include/boost-1_32/boost/mpl/map/map10.hpp:19, from /usr/local/include/boost-1_32/boost/mpl/map/map20.hpp:19, from /usr/local/include/boost-1_32/boost/mpl/map.hpp:36, from temp.cpp:3: /usr/local/include/boost-1_32/boost/mpl/map/aux_/iterator.hpp:39: error: wrong number of template arguments (2, should be 1) /usr/local/include/boost-1_32/boost/mpl/void.hpp:37: error: provided for `template<class T> struct boost::mpl::is_void_' /usr/local/include/boost-1_32/boost/mpl/map/aux_/iterator.hpp:39: error: `type' is not a member of `<declaration error>' /usr/local/include/boost-1_32/boost/mpl/map/aux_/iterator.hpp:39: error: `type' is not a member of `<declaration error>' /usr/local/include/boost-1_32/boost/mpl/map/aux_/iterator.hpp:40: error: template argument 1 is invalid /usr/local/include/boost-1_32/boost/mpl/map/aux_/iterator.hpp:42: error: expected `{' before '>' token /usr/local/include/boost-1_32/boost/mpl/map/aux_/iterator.hpp:42: error: expected unqualified-id before '>' token /usr/local/include/boost-1_32/boost/mpl/map/aux_/iterator.hpp:42: error: expected `;' before '>' token /usr/local/include/boost-1_32/boost/mpl/map/aux_/iterator.hpp:60: error: expected nested-name-specifier before "item_by_order" /usr/local/include/boost-1_32/boost/mpl/map/aux_/iterator.hpp:60: error: ISO C++ forbids declaration of `item_by_order' with no type /usr/local/include/boost-1_32/boost/mpl/map/aux_/iterator.hpp:60: error: expected `;' before '<' token
