Re: [Boost-Users] tuple and enums

Hi Tom, Your code compiles fine with gcc 3.x and icc 6 (linux), so it may just be gcc 2.96 problem. Cheers, Jaakko On Wed, 28 Aug 2002, Tom Matelich wrote:

It appears that an enum cannot be default constructed in the way that tuple does, cons() : head(), tail() {}

Any idea on how to get around this (besides using an int in the tuple)?

Thanks, Tom

#include #include <string>

enum Foo { Willis, Arnold };

void test() {       boost::tuple a; }
