PPC: problems with C++ templates

bob_ubi — Thu, 05 May 2011 04:09:21 GMT

Hi All,

I am trying to cross-compile an application that uses std::tr1::tuple. I have this declaration in std::tr1 namespace:

template <int k, typename T0>

class tuple<T0> {...}

template <int k, typename T0> MyType

get(const tuple<T0>& t) {...}

When I tested with this code:

tuple<int> t;

int N = 1;

...

r = get<N-1>(t);

I got an error from mwcceppc.exe like what it cannot find get because it is looking for this:

get<0, tuple<int, std::tr1::nat, std::tr1::nat, ...>>(const tuple<int, std::tr1::nat, std::tr1::nat, ...>&)

I was expecting this instead:

get<0, tuple<int>>(const tuple<int>&)

I am wondering where is this padding std::tr1::nat come from? Could I tell the compiler to not insert the padding?

Your help is appreciated.

This case is compiled well with MSDEV-2008. mwcceppc.exe -version gave

First, unless there is a compelling reason NOT to, I would update to a later (higher version) of CodeWarrior. Second, it seems like you need the big guns for this issue, so I would file an on-line service request. Click here to go to the service request page. For Topic choose Software Product Support, and for Category choose CodeWarrior. Be prepared to give them a section of code that reproduces the problem.

Hi Tom,

Thanks for the reply. Because of XYZ- third-party issues, the version of the compiler is imposed on me

But I am eager to hear solutions from you.

At this point, file a service request, unless someone knowledgeable in C++ in the forums posts a solution.
