Support for macOS 10.14 (Mojave)

[Anuken]

Unsure if the output is useful for non-10.14 users

I had someone test it on a 10.13 machine, and it appears to work - looks like an issue specific to compilation on Catalina and above. I'll use the dylib from your branch, thanks.

Seems like something which might be possible to automate on a cloud build farm with macOS support, right?

Github Actions doesn't support anything below Catalina as far as I'm aware, and I don't know what other services to use.

when the build targets macOS 10.15.

It does not. In fact, the build has always targeted 10.9. Every single build flag points to 10.9 as a minimum. The latest MacOS versions seem incapable of targeting 10.14 or below, and the only thing that worked for me in the past was compiling these natives on an ancient Macbook running High Sierra. This laptop is completely dead now, so there's no way for me to do that.

@Anuken: ah, yes. Figured it was something in the build environment for these prebuilt files, rather than in the source code.

I hear you on outdated and failing hardware. Only clinging on to this old installation to play games which broke when the "new 10.15" was released. Seems the issue is now that the "old 10.14" isn't supported...

It'd be nice to know if there's another compatibility flag or workaround available, but this issue may be closed at your convenience as that seems unlikely.

[joelpurra]

@Anuken: by the way, which is the effective minimum macOS version now? The Steam store page for Mindustry still says 10.9, but guess that'll change when v7 stable is publicly released.

I've tried many different flags & build types, but none of them made a difference. You could try compiling it yourself (brew install ant sdl2 glew ./gradlew backends:backend-sdl:jnigenBuild) and see what happens with the dylib in backend-sdl/libs/macosx64.

[joelpurra]

Sure!

brew install ant sdl2 glew

# NOTE: using OpenJDK.
brew install openjdk
export PATH="/usr/local/opt/openjdk/bin:$PATH"

./gradlew backends:backend-sdl:jnigenBuild

With the rebuilt backends/backend-sdl/libs/macosx64/libsdl-arc64.dylib library files in ../Arc, the latest Mindustry commit on master (Anuken/Mindustry@47dc9c7) works! =)

Unsure if the output is useful for non-10.14 users but feel free to cherry-pick the commit, or ask and I'll create a pull-request with the same.

Outdated arm64 build details

Seems @Anuken performed the same (effective) change in backends/backend-sdl/build.gradle at the same time; rebased on top of the current master. Ignore the below, only kept for possible arm64 build issue reference.

Build failed for arm64 with #error architecture not supported (full output below). Excluding arm64 from the build by removing -arch arm64 worked, although that deleted the built library file too.

Have some (presumably outdated) build tools on this old macbook, but arm64 supports seems to require something newer. Reinstalling/updating Apple's Command Line Tools didn't bring arm64 support, and the latest XCode in the App Store says 10.14 isn't supported.

./gradlew backends:backend-sdl:jnigenBuild with arm64

Welcome to Gradle 7.2!

Here are the highlights of this release:
 - Toolchain support for Scala
 - More cache hits when Java source files have platform-specific line endings
 - More resilient remote HTTP build cache behavior

For more details see https://docs.gradle.org/7.2/release-notes.html
