Re: [Boost-users] please help : Error: Unexpected type name

yes, the file relation of my test code is : main.C is placed in .../boost_1_35_0/test/ boost is in .../boost_1_35_0/ CC version : Forte Developer 7 C++ 5.4 Patch 111715-18 2006/11/02 and errors are : CC -g -I../. -c -o main.o main.C ".././boost/lambda/detail/function_adaptors.hpp", line 203: Error: Unexpected type name "boost::lambda::Arg1" encountered. ".././boost/lambda/detail/function_adaptors.hpp", line 203: Error: Cannot cast from int to boost::lambda::Result.
