Compile a 32-bit shared library from a 64-bit Linux machine with 64-bit MATLAB installed

Hi, I have a 64-bit MATLAB (with compiler) installed on a 64-bit Linux machine. I would like to compile my scripts into a 32-bit shared library so it can be deployed to a 32 bit linux machine. I have tried to pass -m32 to the gcc compiler by modifying the mbuild options file but that doesn't seem to work. I'm just wondering if it's possible to do what I just described? Or shall I just install a 32-bit MATLAB? Thank you.

Hi,

it's at least difficult, but I guess probably not possible at all. It will definetely simpler to just install a 32 Bit MATLAB in parallel ...

I agree. 32-bit MATLAB is the way to do. Especially because the 32-bit library will need to link against MATLAB runtime libraries which also need to be 32-bit.

Thank you guys for your helpful suggestions.

I had also come to the conclusion that installing a 32-bit MATLAB is much easier than anything else.

Worth mentioning is my 64-bit machine runs a CentOS that comes with SELinux. SELinux prevents 32-bit MATLAB to start and here's a whole page dedicated on how to work around this problem.
