I'm not certain if this is an asio issue or spirit2 issue (or user error).
I checked Spirit out from the trunk and placed it into a 1.37 boost tree. I'm running gcc 4.3.2. Creating file foo.cpp with the following:
---------------
#include <boost/asio.hpp> #include <boost/spirit/include/qi.hpp>
---------------
Produces a string of errors including this snippet:
from ../src/foo.cpp:3: ../../../library/vendor/boost/boost/proto/make_expr.hpp: At global scope: ../../../library/vendor/boost/boost/proto/make_expr.hpp:935: error: expected nested-name-specifier before numeric constant ../../../library/vendor/boost/boost/proto/make_expr.hpp:935: error: expected ‘>’ before numeric constant ../../../library/vendor/boost/boost/proto/make_expr.hpp:940: error: type/value mismatch at argument 3 in template parameter list for ‘template<class Tag, class DomainOrA0, class A0, class A1, class A2, class A3, class A4, class Void> struct boost::proto::result_of::make_expr’ ../../../library/vendor/boost/boost/proto/make_expr.hpp:940: error: expected a type, got ‘0’ ../../../library/vendor/boost/boost/proto/make_expr.hpp:940: error: expected initializer before ‘const’
Hmm, I'm not able to reproduce this problem. What Spirit2 are you using? The one released in Boost V1.36-1.39 or the one on the trunk? Regards Hartmut
