Description Andrew Savchenko gentoo-dev

2009-12-06 19:03:15 UTC

Hello, it dies with the following:

/var/tmp/portage/x11-libs/qt-core-4.6.0/work/qt-everywhere-opensource-src-4.6.0/bin/lrelease: symbol lookup error: /var/tmp/portage/x11-libs/qt-core-4.6.0/work/qt-everywhere-opensource-src-4.6.0/bin/lrelease: undefined symbol: _ZN9QListData7detach3Ev

and ldd var/tmp/portage/x11-libs/qt-core-4.6.0/work/qt-everywhere-opensource-src-4.6.0/bin/lrelease shows:
        linux-gate.so.1 =>  (0x6f6eb000)
        libQtXml.so.4 => /usr/lib/qt4/libQtXml.so.4 (0x6f6b7000)
        libQtCore.so.4 => /usr/lib/qt4/libQtCore.so.4 (0x6f4df000)
        libpthread.so.0 => /lib/libpthread.so.0 (0x6f48c000)
        libstdc++.so.6 => /usr/lib/gcc/i686-pc-linux-gnu/4.4.2/libstdc++.so.6 (0x6f3a0000)
        libm.so.6 => /lib/libm.so.6 (0x6f378000)
        libgcc_s.so.1 => /usr/lib/gcc/i686-pc-linux-gnu/4.4.2/libgcc_s.so.1 (0x6f35b000)
        libc.so.6 => /lib/libc.so.6 (0x6f1f0000)
        libz.so.1 => /lib/libz.so.1 (0x6f1de000)
        libgthread-2.0.so.0 => /usr/lib/libgthread-2.0.so.0 (0x6f1da000)
        librt.so.1 => /lib/librt.so.1 (0x6f1d0000)
        libglib-2.0.so.0 => /usr/lib/libglib-2.0.so.0 (0x6f0ff000)
        libdl.so.2 => /lib/libdl.so.2 (0x6f0fb000)
        /lib/ld-linux.so.2 (0x6f6ec000)

So it tries to use system-wide old qt-core libraries instead of its own. System library doesn't contain _ZN9QListData7detach3Ev symbol, but /var/tmp/portage/x11-libs/qt-core-4.6.0/work/qt-everywhere-opensource-src-4.6.0/lib/libQtCore.so.4.6.0 does:

objdump -T libQtCore.so.4.6.0 | grep _ZN9QListData7detach3Ev
00081090 g    DF .text  0000008f  Base        _ZN9QListData7detach3Ev

So this should be fixed, probably by a proper LD_LIBRARY_PATH

Hmm, simply setting LD_LIBRARY_PATH="${S}/lib" doesn't help, maybe emake redefines it somewhere.

What's the output of scanelf -r /var/tmp/portage/x11-libs/qt-core-4.6.0/work/qt-everywhere-opensource-src-4.6.0/bin/lrelease ?

Disable ccache and try again

(In reply to comment #7)
> Disable ccache and try again

I tried to disable distcc, ccache and use -j1. Failure was the same. After all of this I unmerged x11-libs/qt-* from my system and emerged them again. The latter helps.

(In reply to comment #6)

Due to workaround above it is very hard to answer your question now: I need to remove x11-libs/qt-*4.6.0*, emerge 4.5.3, check and than switch all things back, and all of this without distcc and ccache -- sorry too hard to realize.

Comment 9 Andrew Savchenko gentoo-dev

2010-01-10 17:05:28 UTC

I hit this bug on another system during update from qt-core-4.5.3-r2 to 4.6.0-r1.

# scanelf -r /var/tmp/portage/x11-libs/qt-core-4.6.0-r1/work/qt-everywhere-opensource-src-4.6.0/bin/lrelease 
 TYPE   RPATH FILE 
ET_EXEC /usr/lib/qt4 /var/tmp/portage/x11-libs/qt-core-4.6.0-r1/work/qt-everywhere-opensource-src-4.6.0/bin/lrelease

Will try without ccache and distcc later, though I doubt this will help.

Hmm, without ccache and distcc and with -j3 it works this time, strange.
Anyway you may consider this issue as a closed one.
