[Boost-users] [Fwd: boost::bind vs. boost::lambda::bind - bug]

The code below fails to compile on g++ (GCC) 3.4.3: lambda_bind_test.cxx:9: error: `_1' undeclared (first use this function) lambda_bind_test.cxx:9: error: (Each undeclared identifier is reported only once for each function it appears in.) Commenting the include of boost::bind fixes it. How can the second header hide types defined in the first header? Shall I report a bug in trac or reopen this one?: https://svn.boost.org/trac/boost/ticket/3075 Is there any way in the long run the two libraries could be unified? All the asio examples use boost::bind? Should developers starting out a new code base use just one? Which one? #include #include //comment this line out and it compiles int foo(const char*); void test(){ using namespace boost::lambda; bind(foo,_1); }
