CrossCompile for 32bit on 64bit: Missing Links for .so in /usr/lib/i386-linux-gnu

[mrw]

Package: I see this bug e.g. in all libqt4-*:i386 packages that are installed into /usr/lib/i386-linux-gnu in an amd64 installation.

I cross compile for 32bit on a 63bit PC, that's why I install ia32...-packages.

With oneiric ocelot, libQtCore etc. are no more installed in /usr/lib32, instead, I find them in /usr/lib/i386-linux-gnu. but there ist no libQtXXX.so file, only libQtXXX.so.4 and libQtXXX.so.4.7.

There should be a link from libQtXXX.so.4 to libQtXXX.so, otherwise the gcc-linker cannot find the library.

BUGFIX:

I run:

cd /usr/lib/i386-linux-gnu/
for file in $(find -name '*.so.[0-9]'); do test -e ${file%.[0-9]} || sudo ln -s $file ${file%.[0-9]}; done

But this should be done automatically, when the package is installed.

Status changed to 'Confirmed' because the bug affects multiple users.

$ apt-file -a i386 search libQtCore.so
libqt4-dbg: /usr/lib/debug/usr/lib/i386-linux-gnu/libQtCore.so.4.7.4
libqt4-dev: /usr/lib/i386-linux-gnu/libQtCore.so
libqtcore4: /usr/lib/i386-linux-gnu/libQtCore.so.4
libqtcore4: /usr/lib/i386-linux-gnu/libQtCore.so.4.7
libqtcore4: /usr/lib/i386-linux-gnu/libQtCore.so.4.7.4

i think this happens for the mayority of libqt* packages
all the symlinks are on libqt4-dev instead of every particular package

maybe all this should be moved from libqt4-dev to corresponding libqt**:arch, but really dont know if all this will suffice

I also have this "bug", it's related to multiarch against -dev packages conventions.

One solution would be to provide a link to all arch in -dev package even if .so are missing on the system.

Or create a new <package>-multilib-dev with symbolic links (eg: libqt4-gui-multilib-dev:amd64, libqt4-gui-multilib-dev:i386, etc...).
