I'm trying to run the web-webkit browser on my PowerPC system (built using Poky).
I've built this on ARM and it runs great, but on PowerPC it fails almost immediately.
Following into the failure with GDB, it looks like it's trying to build up a string
using a [possibly] wide character iterator. It fails on line 76 of the code below,
going through it by hand shows that 'iterator' is NULL.
(gdb) dir /local/logopak8347tbga_new/tmp/work/ppc603e-amltd-linux/webkit-gtk-1.5.1+svnr90727-r0
(gdb) l
71 TextBreakIterator* acquireLineBreakIterator(const UChar* string, int length, const AtomicString& locale)
72 {
73 UBreakIterator* iterator = LineBreakIteratorPool::sharedPool().take(locale);
74
75 UErrorCode setTextStatus = U_ZERO_ERROR;
76 ubrk_setText(iterator, string, length, &setTextStatus);
77 if (U_FAILURE(setTextStatus)) {
78 LOG_ERROR("ubrk_setText failed with status %d", setTextStatus);
79 return 0;
80 }
(gdb) b 75
Breakpoint 1 at 0xf8a7440: file Source/WebCore/platform/text/TextBreakIteratorICU.cpp, line 75.
Any ideas what might be wrong here? Maybe some confusion about wide vs not-wide
character representation (I've seen this one a lot, especially on PowerPC systems)?
Any clues where to look next?
I did note that 'locale' into this function is also NULL.
Should I file a bug?
Note: I tried this with the stock Poky master 9d1db6cc928199f8ac4960e8d4648563ef141427
building for qemuppc and running web2 via ssh -X (since qemu doesn't support graphics?)
The failure is the same, so this is not something special in my setup.
Note 2: it's difficult to get this to fail when running in qemu since it only fails
when it's loading and rendering the www.google.co.uk default page. I couldn't figure
out how to get my qemu system to be able to access that page over the net, but I ran
the same Yocto filesystem on my hardware (this is not a hardware bug) with the same
failure. Maybe someone smarter than me can show me how to get qemu to actually access
the internet (when the machine that's running qemu is inside a NAT'd zone)?
Thanks for any help/ideas
