Hi I recently did a fresh install of SL6 x86_64 (formerly running SL5.3 x86_64) and realized that the 32 bit libraries were not installed. SL6 is up-to-date and I have installed the NVIDIA drivers from NVIDIA. One application returns the following when trying to run the gui version but the command line version works as expected. libSM.so.6: cannot open shared object file: No such file or directory I have looked in the "Add/Remove Software" application for the "32 bit libraries" package but could not find them. I have also tried to install the 32 bit (i686) version of the libraries using rpm. The rpm command and resulting error are: [root@SL6box ~]# rpm -i ftp://ftp.scientificlinux.org/linux/scientific/6x/x86_64/os/Packages/libSM-1.1.0-7.1.el6.i686.rpm error: Failed dependencies: libuuid.so.1 is needed by libSM-1.1.0-7.1.el6.i686 libuuid.so.1(UUID_1.0) is needed by libSM-1.1.0-7.1.el6.i686 [root@SL6box ~]# rpm -i ftp://ftp.scientificlinux.org/linux/scientific/6x/x86_64/os/Packages/libuuid-2.17.2-6.el6.i686.rpm package libuuid-2.17.2-6.el6_0.1.x86_64 (which is newer than libuuid-2.17.2-6.el6.i686) is already installed I have also tried to include the i686 repo under yum but have received the same results. Is there another way of installing the 32 bit libraries? As the missing libraries are most likely graphics related, is there a subset of libraries I should install? Or should I install SL 5.5 or Fedora? Thank you Emilio
