Hi all new to the list. When trying to build a rather large project which uses boost, I get the following few lines 12 times during the build process: 7>c:\local\boost_1_60_0\boost\intrusive\detail\has_member_function_callable_with.hpp(303): error C2065: 'BOOST_INTRUSIVE_HAS_MEMBER_FUNCTION_CALLABLE_WITH_ITERATION' : undeclared identifier 7>c:\local\boost_1_60_0\boost\intrusive\detail\has_member_function_callable_with.hpp(320): error C4430: missing type specifier - int assumed. Note: C++ does not support default-int 7>c:\local\boost_1_60_0\boost\intrusive\detail\has_member_function_callable_with.hpp(320): error C2143: syntax error : missing ';' before ''template<'' Others can build this same project just fine and I can't find anything on the internet which would indicate others having problems with this file. I am using VS2010 Professional Version with SP1. My compiler and boost libraries are both 32 bit. I tried uninstalling and reinstalling everything but same errors. These are the only errors which prevent my project from successful build. Any ideas as to what could cause this? -Greg
