Can 32-bit and 64-bit code be mixed? [duplicate]

Answer 1

No its not possible. You cant call any 32 bit lib from 64 bit code. You have to put them in different address space.

One way to utilize it is to use interprocess communication (pipe, socket etc).

Answer 2

Basically, no, you can't link, statically or dynamically, 32bit and 64bit code, not on x86 anyway.

What you can do is write a wrapper that runs in a separate process and uses RPC to "link" the library to your code. nspluginwrapper on Linux does something like that for Flash.
