I have open SuSE 10.2 32 and 64 bit installed on the same machine.
I compile a small matlab example under 32b (either by booting 32b linux or
-m32 compiler flag) and run under 32 and 64 bit linux. The code compiles
under both environments.
However, the code runs normally under 32b linux, but the 64b linux runtime
causes an error condition and the sample code exits.
As a workaround, you can install and run the 32-bit version of Matlab under
64-bit openSUSE. On our servers, we put the 32-bit version
into /lw/matlab/7.4 and the 64-bit one into /lw64/matlab/7.4. The command
that simulates the 32-bit environment under 64-bit linux is "linux32":
$ /lw64/matlab/7.4/bin/matlab # start 64-bit matlab
$ linux32 /lw/matlab/7.4/bin/matlab # start 32-bit matlab
To install the 32-bit version of Matlab, run "linux32 install".
If I remember it right, several Matlab toolboxes were available for the 32-bit
version only some time ago. In other words, they were 32-bit and didn't run
under the 64-bit Matlab---just as your code. Mathworks may tell you more.
