[DYLAN] RPATH issue with qt5's qtwebkit

[DYLAN] RPATH issue with qt5's qtwebkit

[Trevor Woerner]

[-- Attachment #1: Type: text/plain, Size: 1023 bytes --]

Hi,

When I try to include "qtwebkit" in my image from the "dylan" branch I end
up
with the following QA do_package_qa error [note that this does not happen
with "master"]:

ERROR: QA Issue: package qtwebkit contains bad RPATH
/home/trevor/build/yocto/tmp/dylan/work/armv5te-poky-linux-gnueabi/qtwebkit/5.0.2-r0.0/build/lib
in file
/home/trevor/build/yocto/tmp/dylan/work/armv5te-poky-linux-gnueabi/qtwebkit/5.0.2-r0.0/packages-split/qtwebkit/usr/lib/qt5/libexec/QtWebProcess

And the QA test is correct. When I "objdump -x" this binary I get:

Dynamic Section:
  NEEDED               libQt5WebKitWidgets.so.5
  NEEDED               libQt5WebKit.so.5

  RPATH
/home/trevor/build/yocto/tmp/rdk/work/armv5te-rdk-linux-gnueabi/qtwebkit/5.0.2-r0.0/build/lib

Can anyone suggest any fixes or patches? Note I'm using 5.0.2.

Best regards,
    Trevor

Check the compile logs. Somewhere, something is passing a -rpath value
to the linker which results in this. You'll have to find out where it
gets passed in, then trace it back to the source of the problem.
Sometimes this can get added by libtool but there will still be
something on the commandline which triggers libtool to do that.

Cheers,

Richard

Try adding a .bbappend with the following content:

#################
DEPENDS += "chrpath-replacement-native"
EXTRANATIVEPATH += "chrpath-native"

PRINC := "${@int(PRINC) + 1}"

do_install_append() {
        # Remove rpath from the offending binaries
        chrpath -d ${D}${OE_QMAKE_PATH_LIBEXECS}/QtWebProcess
}
#################

That should do it.

Is this something everyone building qtwebkit is seeing? I had just
assumed that it had something to do with other changes I do to
meta-qt5, but if it affect everyone I guess it could be done in
meta-qt5 instead of local bbappends.

Cheers
Erik

Yes I think everyone is seeing it, but in many distro configs bad RPATH
is only QA warning not error (that's why I was partially ignoring it
until now, concentrating on other issues).

You can see do_configure_append in qtwebkit.inc which is removing bad
rpath from qmake generated Makefile, this sometimes doesn't work, from
similar Makefile issue in qtjsondb I know that "sometimes" Makefile
generated in do_configure is regenerated later in do_compile or
do_install task, I'm not sure yet why, but that's what breaks similar
hack in qtjsondb_git.bb:do_configure_append().

Of course the real fix for both issues would be to fix .pri/.prf files
to prevent incorrect Makefile to be generated at all.

Yes, I've been seeing the exact same thing. Although this _append
claims to be fixing the rpath issue, I'm still seeing QA issues (which
lead to errors) build packaging qtwebkit.

Interestingly enough, the _append you mention is only trying to fix
QtWebProcess but I'm seeing this rpath error occur on both it and
QtWebPluginProcess.

As you, Richard, and everyone else has mentioned it would be nice to
have a "proper" fix instead of things which patch up files afterward.
This is why I like Marek's proposal since it fixes the *.prf file
before the build. Looking through that patch, however, I'm wondering
if it couldn't be a little cleaner? Marek's patch simply comments out
a couple lines. I think it would be cleaner to just remove the lines
that are causing problems and/or investigate whether or not that *.prf
file is actually needed at all in this build environment.

Are there any comments on what Marek has targetted? Would others
consider this a "proper" fix (if the patch were cleaned up)?

Best regards,
    Trevor

The above is a workaround, the proper fix is to track down why this is
making its way in there in the first place and fix the problem at
source.

Just my 2 cents.
I have similar issue some time ago and I fix it following way (it's
also workaround and maybe help somebody to find correct solution):

I haven't checked how qtwebkit is built or meta-qt5, but the Qt's
configure has -no-rpath option. A grep on meta-qt5 doesn't show any
usage of it.

A "-no-rpath" option looks like something that might be passed to
./configure? I'm not sure if things are done differently on master,
but on dylan qmake is used to generate the Makefiles. Or is
"-no-rpath" something that can be passed to "qmake"?

It's a configure argument. Unfortunately, it doesn't help in this case.
afaics, most distro are using chrpath hack to get rid of it in
QtWebProcess and QtWebPluginProcess.
A "proper" fix ins't available yet... it doesn't seem trivial, see
https://github.com/WebKit/webkit/commit/069ee433aba1ae8ae5107784b22bd6ade830a012

That's good to know. For some odd reason (as Martin pointed out) the
chrpath hack in OE doesn't always seem to kick in. In my case it
always fails so I'll try to target the "proper" fix.

Excellent! Thanks for digging this up :-)

It *appears*, however, that this patch has already been applied to the
sources obtained from meta-qt5's 5.0.2 build (although I can't seem to
verify that conclusively via the ChangeLog). If I look through the
sources the comments at the bottom of, and lack of qt4 specifics in,
Tools/qmake/mkspecs/features/rpath.prf would appear to match.

I'll create a patch based on what Marek had done and see what people
think of it. In this case, though, I'm not sure how to assign credit
(is there a "based-on-the-previous-work-of SOB-type line?).

Best regards,

I have created two patches:
