Bug 135819 – progress towards building WebCore with CMake on Mac

• Component: WebCore Misc.
• Status: RESOLVED FIXED

[Alex Christensen]

The ObjC bindings have a few things that are different than other bindings.  There are also a few quirks I've found.

I don't think this is quite right, since it breaks an existing port that relies on CMake for its builds. Otherwise I think the general approach is good.

Can these just be commented out with a FIXME(Bug ###) comment?

> Source/WebCore/PlatformMac.cmake:-146
> -    platform/mac/WebCoreView.m

Where did this go? Do we not have this file anymore?

> Source/WebCore/PlatformMac.cmake:-166
> -    platform/network/cf/ProtectionSpaceCFNet.cpp

Ditto.

> Source/WebCore/PlatformMac.cmake:-204
> -    plugins/mac/PluginViewMac.mm

Were these removed?

> Source/WebCore/bindings/scripts/CodeGeneratorObjC.pm:384

Can you make this a FIXME(Bug XXX) comment, please?

> Source/cmake/OptionsMac.cmake:212
> +WEBKIT_OPTION_DEFAULT_PORT_VALUE(ENABLE_IOS_AIRPLAY_iphonesimulator OFF)

You should have a FIXME(Bug XXX) here to remind you to turn these back on.

> Source/cmake/WebKitMacros.cmake:37
> +macro(GENERATE_BINDINGS _output_source _input_files _base_dir _idl_includes _features _destination _prefix _generator _extension _idl_attributes_file)

This is causing the EFL build to fail. You need to add the 'cpp' target to those CMake files.

Will do, once I see the EWS response to this patch.

It doesn't know what to do with .m files right now.  I was removing it to get other things to compile.  I'll get rid of this change.

They aren't in the mac build any more.  Maybe. I don't know what they are.

I think plugins/mac is dead code.  I'll remove it in a separate patch.
ProtectionSpaceCFNet.cpp is only used in the AppleWin port.  I had added it to the Mac build accidentally with the other CF files.

You could use the same code in both cases by finding the bindings dir using:

use FindBin;

my $bindingsDir = dirname($FindBin::Bin);
my $fileName = "$bindingsDir/objc/PublicDOMInterfaces.h";

That's what we do in CodeGeneratorGObject.pm

Done.

I think the Mac WK2 test failures have nothing to do with this.

LGTM - as it seems the Gamepad code is not yet enable in any existing cmake-based ports anyways, so this will not cause a regression.
