I'd be real interested to know what version of GCC is complaining about this. I don't see this error on Fedora 8/GCC4.1, and I've never had an e-mail about it or antyhing. The code, as far as I can tell, is perfectly valid C++. Perhaps I can come up with a workaround for this, as I really do believe it's valid C++... > And Windows build: > > 3>------ Build started: Project: osgWidget, Configuration: Debug Win32 ------ > 3>Compiling... > 3>WindowManager.cpp > 3>.\src\WindowManager.cpp(191) : error C2440: 'initializing' : cannot > convert from 'const osgWidget::Window *' to 'osgWidget::Window *' > 3> Conversion loses qualifiers > 3>.\src\WindowManager.cpp(203) : error C2440: 'initializing' : cannot > convert from 'const osgWidget::Widget *' to 'osgWidget::Widget *' > 3> Conversion loses qualifiers > 3>.\src\WindowManager.cpp(333) : error C2440: 'initializing' : cannot > convert from 'const osgWidget::Window *' to 'osgWidget::Window *' > 3> Conversion loses qualifiers > [...] This is the exact same problem as above. I can definitely come up with a workaround, but if possible I'd like to see your version of GCC first if possible. :) > Thibault > > On Tue, May 13, 2008 at 5:03 PM, Jeremy Moles <[EMAIL PROTECTED]> wrote: > > I've put the (hopefully!) final version of a separate osgWidget up on > > the googlecode site: > > > > http://osgwidget.googlecode.com > > > > This means that I feel like I'm getting closer to the point where it > > would make sense to submit osgWidget to Robert to see how he feels about > > inclusion into the main trunk, with ongoing development there instead. > > This will expose far more eyeballs to osgWidget's codebase, which can > > only be good as development continues. > > > > The next version (I'll call 0.2.0 for now) will be the one I submit, and > > I'm going to construct a serious TODO list of items on the website > > project page of things I want to accomplish prior to this.
