Bug#528485: qt4-x11 - FTBFS: webkit linking fails

[Fathi Boudra (Debian)]

Hi,

By default, debug info are disabled for QtWebkit. It's an upstream choice.
I enabled debug info using 18_enable_qt3support_qtwebkit_debug_info.diff patch 
to provide debug package for QtWebkit. This patch triggered the build failure 
on s390. The linker runs out of memory which is the reason why pristine 
upstream QtWebkit doesn't have debugging symbols at all.

For our users, we should continue to provide QtWebkit debug package.
That means, we can't disable QtWebkit debug info as upstream does.

We have 2 solutions:
a) drop patch 18 and QtWebkit debug package.
or
b) build with gstabs on s390 architecture.

thoughts ?

cheers,

Fathi

s390 uses dwarf2 as default debugging type. This needs much more place
then the default on most arches (stabs). Building webkit with -gstabs
makes it buildable.

On s390, the input in form of object files have about 1.3GiB of size:

| $ du -s .obj 
| 1326696 .obj

ld reads all of them into the memory, even if it is going to throw away
most of them.

The linker call for the webkit library gets killed with about 1.4GiB of used
memory.
