Re: [Boost-users] [Phoenix] expression does not name a type

Dear all,

I can't understand why this test case is not compiling:

#include #include #include #include <iostream>

using namespace boost::phoenix::placeholders; expression::argument<1>::type X;

int main ( int argc, char *argv[] ) { boost::function f; f = if_else( X == 0, X, X*2 ); std::cout << f(0) << f(12) << std::endl; return 0; } // ---------- end of function main ---------- The error message says 'expression' does not name a type. I've tried to explicitly play with boost::phoenix namespaces, but doesn't work.

HTH, Gordon
