Font support is still an issue on all platforms. The STIX fonts that I've gotten ahold of are terrible. Maybe when they ship they'll be better. Uh, they are supposed to be the best math fonts available :-) It is likely that the CSS will have to be customized on each platform to pick the correct expected font from the system.

I am not sure if there is a useful replacement but its good to know about this. Can you elaborate on this? Were these the cause for your memory corruption? If yes, where and how did you solve it? For my own WinCE port I override new delete globally via a special memory pool. I override all 8 signatures of new delete so its supposed to work fine. But... std::stable_sort calls operator new(nothrow) which somehow does not pick up my replacement but it does use my delete replacement. So I end up deleting memory I didn't allocate which as expected crashes. I am still debugging why STL would not use my replacement function, but meanwhile beware about this :-) Regards, İsmail ___ webkit-dev mailing list webkit-dev@lists.webkit.org http://lists.webkit.org/mailman/listinfo.cgi/webkit-dev

No idea if this is helpful or even applies to your problem, but during the Haiku porting effort, we found out that when using USE_SYSTEM_MALLOC=1, WebCore makes some assumptions about alignment of allocations that are not guarenteed when using malloc() (should use memalign()). When we switched to using the built-in TCSystemMalloc, those problems went away. Thats interesting. How did you force TCSystemMalloc for Haiku port?

[webkit-dev] [Qt] Build problem due to newly introduced WebKit/qt/Api/DerivedSources.pro

Trying to build WebKit on Windows I get;
Reading C:/Qt/WebKit/WebCore/WebCore.pro
[C:/Qt/WebKit/WebKitBuild/Release/WebCore]
WARNING: Failure to find: ..\..\..\WebKit\qt\Api\qwebkitversion.h echo

WARNING: Failure to find: =
WARNING: Failure to find: ..\include\QWebInspector echo

WARNING: Failure to find: =
Seems to be due to newly checked in DerivedSources.pro.
Also there is another problem in this file;
DerivedSources.pro line 36 has;
eval(qtheader_module.commands += echo \\\'\$${LITERAL_HASH}include
QtNetwork/QtNetwork\\\' $${qtheader_module.target};)
This won't work since and are special characters for Windows shell so it
has to be double quoted like;
eval(qtheader_module.commands += echo $${LITERAL_HASH}include
QtNetwork/QtNetwork\\\ $${qtheader_module.target};)
