We are considering porting WebKit to work on gaming consoles (e.g. XBox
360, PlayStation 3). We want to have browsing functionality within our
games.
The primary issue with this is likely to be one of memory. When running
within a game, a web browser has little more than a few megabytes of RAM
Upon sync-ing WebKit on Windows/Cygwin, I get this build error for
WebCore.vcproj:
..\loader\CachedImage.cpp(38) : fatal error C1083: Cannot open
include file: 'PDFDocumentImage.h': No such file or directory
This appears to be due to a bug in WebCore.vcproj or a mistake in the
source
I followed the instructions at http://webkit.org on how to sync, build
and run WebKit. However, the last step (run-safari) fails due to
inability to find the CLSID for WebKit.WebView. It appears that some
kind of COM object installation needs to be done in order for this to
succeed. But I can
Thanks, but that fails the same way. Perhaps I'm missing something, but
I don't see how --debug in the scripts solves the problem of a
non-registered CLSID.

I'm wondering if anybody has successfully ported WebKit to a platform
other than Windows or Unix. I ask because I am looking into this
possibility myself. I've looked at Mozilla and WebKit and at first
leaned towards WebKit, as it seems to be easier to grok. But in looking
at the WebKit source

It looks like you are compiling with and EDG-based compiler front end.
EDG can indeed be more strict than other compilers in some cases. My

I see that JavaScriptCore/wtf/Vector.h has this:

hardware. Something like the code

That would be invalid C++. If a given compiler accepts it then the

While a COM or similar interface may result in a library which makes
porting easiest for new platforms, it sometimes can be harder to

is perhaps too
The ScrollView::paint function seems wrong to me too.

FWIW, I rewrote our version of the networking back-end support to use a

gperf (http://www.gnu.org/software/gperf/) is a utility app that

Here's the story: Your GCC 3.4 is compliant to the existing ISO C++

The C++98 and C++03 Standards (see section 5.2.10) do not allow

More generally, all NaN comparisons return false, even with
binary-identical NaNs. So if x is a NaN, then (x == x) is false, as long
