Ok thank you, I will post this on microsoft.public.vc.language. About the other thing, I originally thinked about that. But what to specifiy, using the typedef's won't work either (see below): int i; boost::tuple<int> data(27); i = boost::tuples::get<0, boost::tuple<int>::head_type, boost::tuple<int>::tail_type>(data); //ok i = boost::bind(&boost::tuples::get<0, boost::tuple<int>::head_type, boost::tuple<int>::tail_type>, _1)(data); //error With kind regards, me ----- Original Message ----- From: "Ben Hutchings" Newsgroups: gmane.comp.lib.boost.user Sent: Friday, January 16, 2004 1:30 PM Subject: RE: tuple problems

Dear Booster's

Booster's what?

...

I have a problem compiling a tuple containing an enum in a namespace. For example:

namespace TestTuple { enum ETestTuple { eTestTuple0 = 0, eTestTuple1 = 1 }; }

void Testtuple5() { typedef boost::tupleTestTuple::ETestTuple Tuple; Tuple tpl; }

does not compile. I am using MSVC 2003.net (7.1 version), just native code. Is this a M$ problem or is tuple broken?

Looks like a compiler bug to me.

...

Also I get problem with the combination of boost::bind and tuple, for example:

int i; boost::tuple<int> data;

i = data.get<0>(); //ok i = boost::tuples::get<0>(data); //ok i = boost::bind(&boost::tuples::get<0>, _1)(data); //error

Has anyone a clue?

boost::tuples::get has three template parameters - index, head type and tail type. Usually the type arguments can be deduced, but since you're passing the address to another template function you need to specify all three arguments.

Btw searching lists.boost.org is very hard, because google is out of sync with the list.

Try http://news.gmane.org/index.php?prefix=gmane.comp.lib.boost instead.
