At this point using clearer terminology would help, as .dll refers to
both managed code (assemblies) and native code (Dynamic Link Libraries /
Shared Libraries).

For shared libraries, you don't create .dll files, you create lib.*.so
files.  If you keep the extension out of your [DllImport] declarations,
you don't need to worry about the prefix/suffix differences, e.g.

        [DllImport("foo")] static extern int Frob();

This will look for FOO.DLL on Windows, and libfoo.so under Linux.

The next problem is creating the libfoo.so file.  You can do this with
gcc (for C code) or g++ (for C++ code) along with the -fPIC and -shared
commands, e.g.

        g++ -o libfoo.so -fPIC -shared foo.cpp bar.cpp
