Hi,

We are facing a problem with the library generated by cctools as it's doesn't contain arm64 simulator architecture, which is expected by simulators on the M1 mac machine.
Does cctools generate iPhone simulator arm64 arch slice for a library?

Here is the error:
building for iOS Simulator, but linking in object file (libxyz.a(filename.o)) built for iOS

Thanks,
Dayananda

iPhone Simulator is currently not supported. Do you depend on Simulator support? I might be able to get it working.

@tpoechtrager Thanks for the response.
I've a M1 based macbook whose simulator also has arm64 so wanted to try it out. That will be cool if it works.

Thanks a lot.

@tpoechtrager I have the same issue while trying to build arm64 tvOS simulator binary.
Resulting binary is considered to be built for tvOS. arm64 tvOS and x86_64 tvOS simulator binaries are built correctly.

@naithar To be honest, I don't know. I can't do any testing either. Maybe it's just a warning and we have to wait for the next ld64 open source release.

Could you try building with Apple's Compiler instead of Mainline LLVM? https://github.com/apple/llvm-project

I will try, thanks. But I don't have any experience in this, so it might take a while.

Could the problem be related to the way target platform gets determined in some way? Using arm64 arch for simulator platform seems to force device platform. Is there a way to trace where target platform gets incorrectly defined?

Yes, absolutely possible. You could start with adding -v to the compile command.

For which command should I use this flag? For https://github.com/tpoechtrager/cctools-port/blob/master/usage_examples/ios_toolchain/build.sh or somewhere else? Thanks :)

Edit:
I think I've found flags that I need -tvos_simulator_version_min? But it didn't help.
Changing PlatformSupport.cpp to return only simulator platforms, since it seems like the only place where platform is used, didn't help also.

The compiler is (probably) doing something wrong not the linker. You must examine the compiler.

Add -v to the compiler args.

For the record, as of Apple Clang based on LLVM 15.0.0, I seem to be able to build iPhoneSimulator for arm64 (using SDK 16.4 from Xcode 14.3.1).

I haven't tried with upstream LLVM 15.0.0.

Edit: It builds, but doesn't work it seems. Building an app for iOS simulator with our Godot library built with ioscross, we get:

building for iOS Simulator, but linking in object file built for iOS, file 'libgodot.a'

Are you using the correct SDK and correct target triple? According to ChatGPT it should be something like x86_64-apple-iosXX.Y-simulator

I can build for arm64 iOS simulator just fine with upstream clang 16.0.6 on Linux, the ChatGPT target triple is correct except for the arch, which should be arm64 as they are building for arm64.
You can also use darwinXX as the OS instead of iosXX.Y-simulator, but you might have to add -mios-simulator-version-min=XX to clang arguements

I'm using the correct SDK, but I'm not sure I'm using the target triple correctly.

I was using the default in usage_examples/ios_toolchain/build.sh, after patching the SDK dir:

git clone --progress https://github.com/tpoechtrager/cctools-port
cd /root/cctools-port
git checkout f28fb5e9c31efd3d0552afcce2d2c03cae25c1ca
sed -i '/WRAPPER_SDKDIR/s/iPhoneOS/iPhoneSimulator/' usage_examples/ios_toolchain/build.sh
usage_examples/ios_toolchain/build.sh /root/files/iPhoneSimulator16.4.sdk.tar.xz arm64

Now reading you I see that I might need to patch usage_examples/ios_toolchain/build.sh further, or do all build steps manually to fully control the parameters.

But I can't seem to pass a target triple as suggested for the cctools-port build:

$ ../../cctools/configure --target="arm64-apple-ios16.4-simulator" --prefix=$TARGETDIR --with-libtapi=$TARGETDIR
checking build system type... x86_64-pc-linux-gnu
checking host system type... x86_64-pc-linux-gnu
checking target system type... Invalid configuration `arm64-apple-ios16.4-simulator': machine `arm64-apple' not recognized
configure: error: /bin/sh ../../cctools/config.sub arm64-apple-ios16.4-simulator failed

It seems my Clang install (from latest osxcross with Apple Clang 15.0.0) doesn't recognize arm64-apple as a valid machine. arm-apple works. But then I can't find a system variant that works for the simulator. The default arm-apple-darwin11 works ok.

For the record, this is my current setup:

It's actually autogen that doesn't recognize the architecture. The best way to work around this would be to use --target=aarch64-... instead of arm64 and then in the wrapper add -arch arm64 to the compiler flags. There might be a chance aarch64- works out of the box without the need of -arch arm64. Depends on what Clang does in the compiler driver.

Or use --target=arm-.... and when compiling stuff add -arch arm64 to the compiler flags.
