Description Émeric Maschino 2014-02-26 07:15:10 UTC
Emerging webkit-gtk fails during compile phase with the following error:

/usr/lib/gcc/ia64-unknown-linux-gnu/4.7.3/../../../../ia64-unknown-linux-gnu/bin/ld: ./.libs/../Source/WebCore/css/.libs/libWebCore_la-ElementRuleCollector.o: Can't relax br (PCREL21B) to `_ZNK7WebCore10SVGElement27animatedSMILStylePropertiesEv' at 0x2522 in section `.text' with size 0x2dd0 (> 0x1000000).
/usr/lib/gcc/ia64-unknown-linux-gnu/4.7.3/../../../../ia64-unknown-linux-gnu/bin/ld: final link failed: Nonrepresentable section on output
collect2: error: ld returned 1 exit status

Tried twice, got the same error twice.

It's noteworthy that I had to apply the two attached patches on ia64:
- webkit-gtk-2.2.5-ia64-platform_h.patch: disable JIT and MacroAssembler as they're not supported on ia64 and build process seems not to honor -DENABLE_JIT=0 -DENABLE_YARR_JIT 0 and -DENABLE_ASSEMBLER 0 when passed at the command-line
- webkit-gtk-2.2.5-ia64-use-system-malloc.patch: to supposedly fix crash on ia64. Since I cannot successfully emerge webkit-gtk, I can't confirm at the moment.

Both the patches are based on Debian's ones, with the exception that webkit-gtk-2.2.5-ia64-platform_h.patch is targeted for ia64 whereas Debian's one was made for hppa.


PS: build.log is _huge_ (>100MB). Even compressed with bzip2, it's still 1.2MB so won't meet Gentoo's Bugzilla file limitations. So, available upon request.

What about running:

on ia64 as we already do for alpha in src_configure?

(Also CCing ia64 people as maybe this kind of "can't relax" error is "familiar" there :/)

Will try.

As a side note, it seems that this problem is more related to ld [1] rather than webkit-gtk. I thus imagine that this bugreport should advantageously be reassigned to Gentoo's toolchain maintainers.


Comment 10 Pacho Ramos gentoo-dev 2014-02-26 21:24:29 UTC
Uh, good catch! Then, maybe dropping the --no-keep-memory we have in ebuild for ia64 will work (even if it will eat lots of memory again :S)

           An option with machine dependent effects.  This option is only supported on a few targets.

           On some platforms the --relax option performs target specific, global optimizations that become possible when the linker resolves
           addressing in the program, such as relaxing address modes, synthesizing new instructions, selecting shorter version of current
           instructions, and combinig constant values.

           On some platforms these link time global optimizations may make symbolic debugging of the resulting executable impossible.  This is
           known to be the case for the Matsushita MN10200 and MN10300 family of processors.

           On platforms where this is not supported, --relax is accepted, but ignored.

           On platforms where --relax is accepted the option --no-relax can be used to disable the feature.

Per "man ld" maybe would be better to drop --no-keep-memory for ia64 as it would be worse at build time but better at runtime :/

What option does it work for you? (if any)

Indeed, removing --keep-no-memory from ebuild allowed me to complete emerge of webkit-gtk. And it even passed tests successfully, with a lot of warnings nevertheless.

Now, the bad news. As a double-check, I've patched sys-devel/binutils-2.23.2 with the patch proposed by Stephan in upstream bug #15904 [1] and enabled --keep-no-memory in ebuild again. Emerge no more fails during final link but during compile phase with:

/usr/include/sys/ucontext.h:51: syntax error, unexpected STRUCT in '     unsigned long _pad[__builtin_offsetof (struct sigcontext, sc_gr[0])/8];' at 'struct'
/usr/include/sys/ucontext.h:53: syntax error, unexpected '}' in '   }' at '}'

As a comparison, without --no-keep-memory in ebuild, the above log snippet looks:
