I am Trying to execute a Visual aplication, but I got the next message:

./track: error while loading shared libraries: libInventor.so: cannot open shared object file: No such file or directory

I execute "ldd" command and I got these message:

linux-gate.so.1 =>  (0xffffe000)
        libInventor.so => not found
        libInventorXt.so => not found
        libpthread.so.0 => /lib32/libpthread.so.0 (0xf76cf000)
        libsfbcomm.so => not found
        librt.so.1 => /lib32/librt.so.1 (0xf76c5000)
        libxvidcore.so.4 => /usr/lib32/libxvidcore.so.4 (0xf75e2000)
        libstdc++.so.6 => /usr/lib/gcc/x86_64-pc-linux-gnu/4.4.4/32/libstdc++.so.6 (0xf74eb000)

        /lib/ld-linux.so.2 (0xf7721000)

How can I to assign the files not found? And also I have to change from libInventorXt.so to libInventorQt.so, How can I do that? I am not root

I hope someone can help me

You need to install the packages that contain libInventor and so on. You can use aptitude or apt-file to find which package you need:

$ apt-file search libInventor.so
inventor-dev: /usr/lib/libInventor.so
libinventor0: /usr/lib/libInventor.so.0
libinventor0: /usr/lib/libInventor.so.0.0.0
$ apt-get install inventor-dev

Should do the trick. Ditto with the rest of the libraries. Clearly installing your programme with apt-get would be ideal if there were a package for it under Ubuntu/Debian.

  • Thanks for answer, I forget tell that I have the Inventor library installed, but it is installed in /usr/include/Inventor, I think that I only need the soname libInventor.so, but I dont know how can I make the soname..

  • In that case you need to set the LD_LIBRARY_PATH variables and add /usr/include/Inventor/lib/ or where ever the library is installed. However, I would recommend against install things manually on a Ubuntu system. Please use the packaging system provided, in the long run it will save you hours of hassle.

  • export LD_LIBRARY_PATH=/path/to/library/directory/:$LD_LIBRARY_PATH

  • I introduce this: export LD_LIBRARY_PATH=/usr/include/Inventor/lib/:$LD_LIBRARY_PATH since the sell, but I get the same error: ./track: error while loading shared libraries: libInventor.so: cannot open shared object file: No such file or directory
