Linux .Net Core calling 32bit .so library file issue

[yb101]

I'm using .Net Core in Linux and able to invoke the functions of my .so library file (64bit). But it will fail if I call the 32bit .so library. The error is simply saying the function can't be found. We would like to know if it's by design. Or if there is a way to call 32bit .so library from Linux .Net Core program? Please kindly advise. @yizhang82 Thanks.

I think this is by design. You cannot call a 32bit native binary in a 64bit process with P/Invoke on Windows, either.

The runtime itself is actually a native process, and being a native process it can only load libraries that match its architecture. .NET Core for Linux only supports 64-bit (and community supports ARM) as far as I know so the libraries it loads must also be 64-bit. You need a 32-bit runtime (which does not exist) if you are going to load 32-bit libraries.

Does anyone know if there is a plan to roll out 32bit .Net Core runtime in Linux?

Looks like on the roadmap It is listed as a "goal" to have a high quality x86 port.

@yb101 As mentioned this is by design since the process is 64 bit , 32 bit coreclr is a much bigger issue . I am closing this bug assuming your question is answered.
