VC8 compiler: definition mis-interpreted as a function declaration

Posted by Microsoft on 2/6/2007 at 10:06 AM

Basically this is a known problem with Visual C++ – we just don’t handle this style of initialization when pointers are involved. I have looked at this issue a couple of times and have always given up as it proved just too difficult to shoehorn this feature into our compiler.

So when we looked at this bug in triage yesterday we decided that it didn’t meet the bar – mostly because of the difficulty and also because there is a workaround – use the ‘=’ form of initialization (which also, in my opinion, has the advantage of being clearer).

It must be nice to be able to use the “too difficult” excuse…

(LGPL License Option Added to Qt)

Espoo, Finland — Nokia today announced that its Qt cross-platform User Interface (UI) and application framework for desktop and embedded platforms will be available under the Lesser General Public License (LGPL) version 2.1 license from the release of Qt 4.5, scheduled for March 2009. Previously, Qt has been made available to the open source community under the General Public License (GPL) license. In addition, Qt will now be available from the new domain, www.qtsoftware.com.

The move to LGPL licensing will provide open source and commercial developers with more permissive licensing than GPL and so increase flexibility for developers. In addition, Qt source code repositories will be made publicly available and will encourage contributions from desktop and embedded developer communities. With these changes, developers will be able to actively drive the evolution of the Qt framework.

Qt 4.5 will also be available under commercial licensing terms, while licensing for previous versions of Qt remains unchanged. In addition, service offerings for Qt will be expanded to ensure that all Qt development projects can have access to the same levels of support, independent of the selected license.

Good news for those of us too cheap to pay the $4950 per developer multi-platform license.
