compiling QT 4.6 on altix problem

Hello

I'm trying to compile QT 4.6 on an altix and running into a problem with templates.

I filed a bug report with QT QTBUG-7356 There was a similar bug using the

g++ complier on an alpha QTBUG-5955

Wondering if anyone else has been able to compile QT 4.6 on an altix or if they

have any insight on how to resolve issue or if this requires a compiler upgrade.

Hi, Rich

You cantry this walk-around:

In file: "src/corelib/arch/qatomic_ia64.h", line 208, modify as following:

[bash]    return (T *)_InterlockedExchangePointer((void * volatile *)&_q_value, newValue);
[/bash]

You can find thedefinition of intrinsic "_InterlockedExchangePointer" in "ia64intrin.h"

[bash]void * _InterlockedExchangePointer(void * volatile *Destination, void *Exchange);[/bash]

Thanks.

Thank You Yolanda

Your work around allowed the compile to continue.

I've updated the bug report to let Trolltech know.
