experimenting with NativeAOT static libs

Requires cmake and .NET 8

Building: shared vs static

By default on Linux and Mac we build a static library using NativeAOT and link it into the main application library libhello. On Windows, the default is a static library unless you do a Debug publish (not the default).

It is possible to override the default on every platform using -p:NativeLib=[shared|static].

Note that on Windows you must build the native bits in the Release configuration to consume a static library. Otherwise there will be native linker errors due to NativeAOT components being compiled with the Release MSVC.

Building on Linux or Mac

$ dotnet publish -r linux-x64 libnaothello/libnaothello.csproj
$ cmake -S app -B app/out
$ cmake --build app/out

Building on Windows

Static library

dotnet publish -r win-x64 libnaothello\libnaothello.csproj
cmake -S app -B app/out
cmake --build app/out --config Release

Only Release config builds work with the static library.

Shared library

dotnet publish -r win-x64 libnaothello\libnaothello.csproj -p:NativeLib=shared
cmake -S app -B app/out

cmake --build app/out --config Release

Default (Debug) build:
