build release/9.0 android and ios local failed

[srxqds]

I have tried to build v9.0.0 tag.

hit error when build android:

the build toolchain not changed from .net8 said from the docs:

https://github.com/dotnet/runtime/blob/v9.0.0/docs/workflow/testing/libraries/testing-android.md

how can I solve it?

I use ubuntu 22.04 in wsl to build android

build android toolchain:

and build ios also hit the error:
fatal error: unicode/uidna.h file not found

I have also install the requirements:

the macos version is Monterey 12.6

I found the icuc4c@76 or icu4c folder both have the uidna.h file

I have export LDFLAGS and CPPFLAGS but not work:

i use macos 14 build ios the error disappear.

so the macos 12 is not supported for building?
