Hi,
I'm trying to cross-compile build Qt 5.0.2 for a TI AM3359 board using the
patches from Thomas Pettazoni. The qt5 build system has been modifed quite
a bit from his original layout but the patches, sequence and commands
are the same.
So far the qtbase, script, svg, xml patterns and image formats modules are
compiling sucessfully. However when compiling the javascript backend
"qtjsbackend" the build fails when running a python script -
python out/build/qt5-5.0.2/qtjsbackend/src/v8/../3rdparty/v8/tools/js2c.py

This seems to be a python script error but I can't figure out what it is.
Any help on this would be much appreciated as I need to this compile
qtdeclarative which depends on this module.
Regards,
Carlos

What do you mean by "it has been modified quite a bit from the original
layout" ? If you're not using the Buildroot code, it means you're
building in a way that is completely unknown to us. In this situation,
how would you want us to help you?

Would be good to find out which thing is segfaulting here.

Please let us know which Buildroot version is used (preferably the
latest Git, or 2013.05-rc1, which is the first release that contained
the Qt5 support), and the corresponding Buildroot .config so that we
can reproduce the issue.
Thanks!
Thomas

I've had frequent build failures in v8 and webkit due to out-of-memory.
Can you check if that is the case? dmesg | tail would give you a hint...
Also try building with BR2_JLEVEL=1 - then at least you see which
command is giving the error.

Arnout

Hi Arnout & Thomas,
Thanks for tips. It got me digging in the (hopefully) right direction.
The issue is basically that host tool "mkv8snapshot" which is part of
qtjsbackend is segfaulting -
mkv8snapshot[29356]: segfault at 0 ip 0833e3b9 sp bf8ec040 error 4 in
mkv8snapshot
I still haven't been able to determine why this happens. But the solution
that works for me is to disable its usage during the Qt build as per the
info in this mail trail from Qt-project
http://comments.gmane.org/gmane.comp.lib.qt.devel/6101
So I added a patch as per below... and no more issues!

I can't exactly figure out why this happens esp becuse it If build qt5
manually "by hand" using the same process (but just outside buildroot, but
with the same cross-toolchain) i dont see this error as the configure
script detects that this tool is not required (canUseV8Snapshot gets set to
no).
Any reasons why this is happening?
regards,
Carlos
