Description Rex Dieter 2014-02-26 20:58:10 UTC
Need to port the javascriptcore/webkit bits to qtwebkit packaging...

+++ This bug was initially created as a clone of Bug #1046360 +++

It's been reported upstream (link below) but it would be useful to get aarch64 support into rawhide to enable easier building of qt and the many packages it's dependent on.

Build here

- Add support for aarch64 (#1046360)

Comment 1 Peter Robinson 2014-02-26 22:51:58 UTC
I think this is mixing qt and qtwebkit? Or do you have the NVR for qtwebkit too?

Comment 2 Rex Dieter 2014-02-26 23:08:45 UTC
I saw the aarch64 qtwebkit build failures, and I think it's due, in part, to similar fixes made to the bundled copy of webkit in qt tarball.

Comment 3 Peter Robinson 2014-02-26 23:10:53 UTC
At the moment the issue is primarily missing or other dep issues which I'm working through, once I get them in place if it still fails I'll update this. Thanks!

add aarch64 support

Comment 8 Rex Dieter 2014-02-28 19:27:35 UTC
OK, pulled in the latest aarch64-related bits from upstream qt5 qtwebkit repo, and it's still failing on:

webkit-qtwebkit-23/Source/JavaScriptCore/assembler/MacroAssembler.h:62:2: error: #error "The MacroAssembler is not supported on this platform."

:( I'm a bit stumped now.  I'll commit what I have to rawhide.

Comment 9 Rex Dieter 2014-02-28 19:33:37 UTC
Marcin, can you give any advice here?

I tried a basic backport of the changes from qt5-qtwebkit and bug #1056160 to qt4's webkit here, but there's apparently more to it... seems related to javascript jit support.

AArch64 patch + disable JIT

This patchset gets us a bit further. There is not JIT for AArch64 so we need to disable it.

Build failed anyway as there is 5.3GB of object files which "ar" is unable to convert into libWebCore.a - looks like 4GB limit.

Comment 11 Kevin Kofler 2014-02-28 22:54:49 UTC
Add aarch64 to this patch:
or make it unconditional altogether. (The conditionals are inside the patch.)
