no versioned library symlinks provided for libGL in /usr/lib

[Johan Van de Wauw]

In the current lucid package libGL.so.1 is no longer installed under /usr/lib
Many programs are built against this versioned library, and the versioned library is available in debian and in ubuntu karmic.

[Scott Ritchie (scottritchie)]

The symlinks are identical to those found in /usr/lib for the native GL library though. This isn't an ia32-libs request, it's a mesa one

Hi Johan,

Please attach the output of `lspci -vvnn` and `dmesg`, and attach your /var/log/Xorg.0.log (and maybe Xorg.0.log.old) file from after reproducing this issue. If you're using a custom /etc/X11/xorg.conf please attach that as well.

The automatic reply was not to the point.
If I look to the debian packages, the versioned library is installed under /usr/lib. This is not the case in ubuntu lucid. There only libGL.so is installed, not libGL.so.1
compare eg:
http://packages.debian.org/sid/i386/libgl1-mesa-swx11/filelist
or
http://packages.ubuntu.com/karmic/amd64/libgl1-mesa-swx11/filelist
and
http://packages.ubuntu.com/lucid/amd64/libgl1-mesa-swx11/filelist

even the package description is: "On Linux, this library is also known as libGL or **libGL.so.1**.
Many programs (eg Google Earth) expect this version in /usr/lib

[Johan Van de Wauw (johanvdw)]

After some research: this bug is similar to lp:505359 . There libGL.so was added to /usr/lib, but the versioned libraries were not.

[Robert Hooker (sarvatt)]

This is not a bug, there is a ld.so.conf.d conffile pointing to the directory libGL.so.1 is installed (/usr/lib/mesa/ for mesa or the directory for whatever package provides your libGL) and things will use that which you can verify with ldd yourapp and ldconfig -p | grep libGL.so

If this is not a bug, then where is the bug in this fresh 64 bit Kubuntu 11.10 install after installing Google Earth:

 - saturn:~$ google-earth
./googleearth-bin: error while loading shared libraries: libGL.so.1: cannot open shared object file: No such file or directory

google earth may not have had correct dependencies.
