what's the reason for this property? why would we want to skip the prefix?

In case of coreclr, the prefixes were not added in the original version. Apparently, there is a job on CI that crosscompile clrjit.so (Linux version) on Windows. That one was failing, so I restored it by skipping the prefix here. It will require a bit more investigation and it can be avoided (at least in theory) 😅

would lib.System.Native (and so forth) be better? more readable than libSystem.Native perhaps

no, this is not the Linux convention. usually `lib' is prefixed without dots.

plus adding the . might make it such that the loader won't find the library automatically as for anybody PInvoking to System.Native, I believe the runtime will try either System.Native or preappending lib, but it won't find it if it also needs to pre-append a dot.

This change, overall, makes me sad. We intentionally stripped off the lib prefix as part of "these aren't general purpose libraries, don't look here". But if we need to, we need to, I guess.

The alternative may be to statically link these libraries into the runtime for Android where it is causing problems. We are going to have this option for single file flavor of CoreCLR anyway, so doing it for Android as well (or even everywhere) should not be a big deal.

statically link these libraries into the runtime

Xamarin.Android does not support this mode. I think this would be nice but we won't be in a position to deliver this for .net5. This looks more like .net6 enhancement because we would need to do native linking during publish phase (this depends on Android NDK, etc).

For CoreCLR, the plan is to statically link the libraries as part of the dotnet/runtime build (see #32823). We are not planning to do native linking during publish phase.

That won't work for us. The thinking right now is to copy the dynamic libs which are used (during publish) and extend that to full static linking for Android as we plan to do for iOS (and wasm) during publish

Just curious - why it does not work for you?

Primary because of size. If an app uses no crypto we should not link libSystem.Net.Security.Native and you can apply that to all native libs where System.IO.Compression.Native is probably the biggest one.

The moment someone brings in any managed HTTP implementation, client or server, it's going to end up requiring both of those. Presumably then the size concern would only be if they were using a platform-specific implementation (e.g. AndroidHttpHandler) where the platform provided all of that support?

Same comment here, this is not only adding lib as a prefix, it is removing our override

I'm not too familiar with this so probably @bartonjs should take a look, but looks like in here you are also changing the override of the default name

and override default name

this part of the comment refers to the line below. There are two variants of this library produced by this script: shared and static. We have prefix override for each which this delta is removing.

Yes this change is correct. We could however preserve the override default name part of the comment for the next line which sets the OUTPUT_NAME on the static lib.
