Bug 102695 – can't build qtwebkit 2.2.2

• Component: WebKit Qt
• Status: RESOLVED INVALID

[Andrea Scarpino]

I get this error building qtwebkit.

I got the qtwebkit 2.2.2 tarball from gitorious[1] (note, there's no 2.2.3 tag there), then I applied the glibc [2] and werror[3] patches.

I googled for this error and I found an old debian bug[4] report which say this is fixed, but seems this isn't.

The Qt port has been removed from WebKit, resolving this bug.
