Load 32-bit shared library from 64-bit application?

I have a shared library that is compiled as 32-bit. Can I use it from a 64-bit application or do I need to compile the shared library as 64-bit as well?

Solution

  • No, you cannot load a 32-bit library in a 64-bit application through conventional means.

    There are some clever hacks out there such as having a 32-bit application which loads the library and exports the functions through an IPC interface, but if you have the option to compile the library as 64-bit, then that is by far the best choice.
