typedef std::size_t count_type;

struct registered_waiter {

The proposed workaround corresponds to the existing code.

Could you tell us if the version 1.49 has yet the error?

[anonymous]

Moved to support request until resolution clarified.

[viboes]

Closed as no answer received. Please reopen it once you have checked it on 1.49 (trunk).

[s.seifried@…]

Still the same problem in 1.50.0. Changing the type trait "typedef std::vector<registered_waiter>::size_type count_type;" to the specific type "typedef std::size_t count_type;" fixed the problem as a quick workaround.

Environment is still the same, stlport 5.1.5 and msvc 8.1.

[viboes]

Could you add the error relative to the fact the stlport 5.1.5 doesn't defines std::vector<T>::size_type?

Are there any compiler flags that can be tested to check for stlport 5.1.5?

[s.seifried@…]

Just double checked, but stlport 5.1.5 does define size_type, and it is a public typedef to size_t. So this is fine from my point of view.

boost 1.50.0 was compiled without any additional compiler flags. If you want to try it out yourself, just grab a copy from stlport 5.1.5 from sourceforge and add it to the appropriate place in user config jam.

[viboes]

I think I've understood what is happening. I will replace

struct registered_waiter;
typedef std::vector<registered_waiter>::size_type count_type;

by

struct registered_waiter;
typedef std::vector<int>::size_type count_type;

As the type std::vector<T>::size_type should not depend on T.
