I am running 64bit Ubuntu Karmic (9.10) and have the same problem. I get the wrong class for the libtiff file:

error while loading shared libraries: libtiff.so.3: wrong ELF class: ELFCLASS64

If you can point me to a 32bit version, much obliged.
But I am not really sure how much 32bit files need to be changed.

Kind regards - kees

hi simong,

alright, that libtiff issue seems to be resolved. I Modified the libtiff link to the 32bit library as follows:

cd /...../medusa4/medsys/med/share/
sudo mv libtiff.so.3 libtiff.so.3.bck
ln -s -f /usr/lib32/libtiff.so.4 libtiff.so.3

Hope this is correct.
Now I get a complaints about libbz2 lib not found:

/cae/medusa/medusa4/medcolraster/m2d/run/draft: error while loading shared libraries: libbz2.so.1: cannot open shared object file: No such file or directory

However, in the directory /usr/lib32 this file is present, though not in lib and lib64. Do I need to set a path to lib32 somewhere, somehow?

Is it likely that (much) more problems like this pop up?

kind regards - kees

Below the install point will be a directory master_project in there a file called login you can edit the path setting there to include the 32 lib directory.

Hi Simong

thank you very much for pointing me in the right direction.
Medusa4 is now running on my system, Ubuntu 9.10, 64bit.

What I did:
back up file login in directory
..../medusa4/master_project/login --> login.bck

In this file ..../medusa4/master_project/login added the following lines:
## added to access 32bit libraries
setenv LD_LIBRARY_PATH \
`edpath -a LD_LIBRARY_PATH /usr/lib32`

(in my file just after path to '.....java/jre/lib/i386')

Then created a link for libbz2.so.1 in the /usr/lib32 directory:
cd /usr/lib32
sudo ln -s /usr/lib32/libbz2.so.1.0.4 libbz2.so.1

Then it runs. Thank you very much again.

kind regards - kees
