Best platform for Android builds

[SvenCarstensen]

Hello everyone,

I have just tried to create a version for Android. But both under macOS and Linux I get error messages when building mdbx-sys.

Under macOS (M4 Pro):

Compiling mdbx-sys v0.0.0 (/Users/svencarstensen/Entwicklung/Source/flutter/isar/isar/packages/mdbx_sys)
error: failed to run custom build command for mdbx-sys v0.0.0 (/Users/svencarstensen/Entwicklung/Source/flutter/isar/isar/packages/mdbx_sys)

Caused by:
process didn't exit successfully: /Users/svencarstensen/Entwicklung/Source/flutter/isar/isar/target/release/build/mdbx-sys-980b6e7dc74ac1cb/build-script-build (exit status: 101)

Under Linux Mint (aarch64):

Compiling mdbx-sys v0.0.0 (/home/sven/dev/isar/packages/mdbx_sys)
error: failed to run custom build command for mdbx-sys v0.0.0 (/home/sven/dev/isar/packages/mdbx_sys)

What have I overlooked? Which platform is best suited for creating this?

Thank you very much!

See you then
