New SDR driver - do I make a DLL/SO or a lib/a or an exe or what?

[Jim Davies]

I'm writing a Soapy driver for an ethernet-connected SDR. All the functions to implement are straightforward and clear, so that's simple enough. But what I cannot work out is what I am supposed to build.

In other words, what type of file is a 'driver'?

Is it a dynamic library, ie dll/so (windows/Linux) or a static library (lib/a) or a kernel driver or what?

I'm building it in VC++ 2022 and/or GCC (ubuntu), if it matters.

Thanks

Jim
