libstdc++.so.5 is missing from gcc-4.3.3_multilib-x86_64-4alien.txz

I play Neverwinter Nights and in order for the movies to play they require libstdc++.so.5, but only libstdc++.so.6 is included in gcc-4.3.3_multilib-x86_64-4alien.txz. I have looked at the slackbuild but cannot see what to do to get the earlier libraries. Does anyone know how to do this?

libstdc++.so.5 is provided by the 3.X.X versions of gcc. The 4.X.X versions of gcc provide libstdc++.so.6 as you have already discovered. You can install just the libstdc++.so.5 from earlier versions of gcc. Here is how I do it on my (non-Slackware) machine

Code:

tar xf gcc-3.3.6.tar.bz2 && 
mkdir gcc-build &&
cd gcc-build &&
../gcc-3.3.6/configure --prefix=/opt/gcc-3.3.6 \
    --enable-threads=posix --enable-multilib \
    --enable-shared --enable-languages=c,c++ &&
make bootstrap &&
cp -av $(gcc -dumpmachine)/libstdc++-v3/src/.libs/libstdc++.so.5* /usr/lib64

Hopefully it gets you started.

Have you tried creating a symlink to .6 and see if it works? I've tried stuff like this in the past. Sometimes it works and sometimes not.

Hi!

Perhaps it is enough to run convertpkg-compat32 on Slackware's 32bit cxxlibs package and install the resulting -compat32 package.
I will add cxxlibs to the list of packages in the massconvert32.sh script so that a -compat32 package will be created automatically from now on.

Cheers, Eric

This resulted in a use-able libstdc++.so.5 in /usr/i486-slackware-linux/lib/, linking this to /usr/lib/ allowed the first movie to play, NWN then froze. So I guess my problem is fixed with regard to Slackware64 I will now try to fix the NWN problem.

Thanks Eric.

I've updated my compat32-tools package so that it will now properly deal with the libraries in the 32bit cxxlibs package. Your manual symlink creation should no longer be needed.
