In my PC there are:
-) Slackware-current with kernel "vanilla" 2.6.15.4
-) OpenOffice.org 2.0.1 (packet from http://www.slacky.it)
-) aMule 2.1.0 from source
-) wxWidgets 2.6.3-rc1 from source

If i start amule in gdb crashes with:  ;(

OpenOffice.org2.0? What it means?  ?(

If I rename OpenOffice.org directory with:
"mv /opt/openoffice.org2.0 /opt/openoffice.org2.tmp"
then aMule don't crashes and works fine!  8o

Why?  X(

Thank you for the help!

gianogli,

It means that openoffice 2.0 has its own version of libstdc++, and that you are using it, and that it has some problem with aMule. This library is in the search path before the correct libstdc++ library. There is probably some error in the openoffice package you got that is messing with your system libraries.

Cheers!

Your "real" libstdc++.so.6 (i.e., the one that came with your system and not with OpenOffice.org) is probably installed in "/usr/lib", right?

If so, you can force searching "/usr/lib" before "/opt/openoffice.org2.0/program" by putting the former into your LD_LIBRARY_PATH before the latter:

Code: [Select]

export LD_LIBRARY_PATH="/usr/lib:/opt/openoffice.org2.0/program"By the way, this OpenOffice.org package is somewhat broken. There is a consensus that packages with private libraries should not expose them system-wide.

Yes!

With the command "ldconfig -p | grep libstdc++" I see:

Code: [Select]

       libstdc++.so.6 (libc6) => /opt/openoffice.org2.0/program/libstdc++.so.6
        libstdc++.so.6 (libc6) => /usr/lib/libstdc++.so.6
        libstdc++.so.5 (libc6) => /usr/i486-slackware-linux/lib/libstdc++.so.5
        libstdc++.so.4 (libc6) => /usr/i486-slackware-linux/lib/libstdc++.so.4
        libstdc++.so.2.9 (libc6) => /usr/i486-slackware-linux/lib/libstdc++.so.2.9
        libstdc++.so.2.8 (libc6) => /usr/i486-slackware-linux/lib/libstdc++.so.2.8
        libstdc++.so.2.7.2 (libc6) => /usr/i486-slackware-linux/lib/libstdc++.so.2.7.2
        libstdc++.so (libc6) => /usr/lib/libstdc++.so
        libstdc++-libc6.2-2.so.3 (libc6) => /usr/i486-slackware-linux/lib/libstdc++-libc6.2-2.so.3
        libstdc++-libc6.1-2.so.3 (libc6) => /usr/i486-slackware-linux/lib/libstdc++-libc6.1-2.so.3
        libstdc++-libc6.1-1.so.2 (libc6) => /usr/i486-slackware-linux/lib/libstdc++-libc6.1-1.so.2The problem is the OpenOffice.Org package that expose its private libraries to the system! But I should see the OpenOffice libraries with "ldconfig -p command" or no? If yes is only a order problem?
Thank you all!

No, it should not be there, but it is.

OpenOffice.org includes this library in order to work on both GCC3 and GCC4 systems. Maybe you don't need it at all because you already have it.

Try do get rid of it:

Code: [Select]

mv /opt/openoffice.org2.0/program/libstdc++.so.6 /opt/openoffice.org2.0/program/libstdc++.so.6.bakIf OpenOffice.org still works afterwards, you don't need this extra library at all.

Otherwise you have to override the order with LD_LIBRARY_PATH, as described above.

By the way, where does this OpenOffice.org package come from? It is not built properly. Packages that need to include such libraries for whatever reason should use wrapper scripts or set their RPATH to $ORIGIN instead of adding the directory to the system-wide search path. Consider filing a bug-report against this package.
