• Component: WebKitGTK
• Status: RESOLVED FIXED

[ChangSeok Oh]

my uild command is 
../../autogen.sh --prefix=/usr/local --disable-egl --enable-debug --disable-webkit2 --with-gstreamer=1.0 --with-acceleration-backend=clutter

And the failure is like following.

We can enable AC clutter backend by running the build script as follows:

./Tools/Scripts/build-webkit --gtk --debug --with-acceleration-backend=clutter --no-webgl --disable-glx --disable-egl

However, it would be good to build it without --disable-glx --disable-egl, so I will try to test Changseok's patch.

Thanks!

Yeap. I know :) But I think it's better if we can build clutter ac feature without such extra options.

That's true for now, but if we ever land the cogl implementation of webgl, then we will probably have to enable some or all.
