I'm developing a internal SDK and I have to build it for iOS:

IPHONEOS_DEPLOYMENT_TARGET=13.0 cargo build --target=aarch64-apple-ios

I expected the static library output would follow the IPHONEOS_DEPLOYMENT_TARGET all the way through when checking with otool:

Instead, some object files were compile with a different IOS target version (17.2) as we can see in the minos of LC_BUILD_VERSION:

In total 1578 but only 145 had these behavior of setting the minos 17.2. Is this behavior expected?

Addtional information that can be relevant:

  • In this project I use OpenSSL v3 compilied locally and exposed to the SDK by a sys crate for it, the bindings for the OpenSSL code were done using bindgen (ref)
  • I also use UniFFI to generate native bindings to Swift (ref)

Those object files are part of the precompiled compiler-builtins crate. They probably need to be compiled with IPHONEOS_DEPLOYMENT_TARGET set to the minimum iOS version we support.

Good, I'm trying to validate this but so far I didn't find the usage of the compiler-builtins crate, I've tryied the command cargo tree --target=aarch64-apple-ios --all-features and I've got the following output:

I know that some of those crates can use the compiler-builtins, like the bitflags crate, but is an optional dependency, so I can say for shure if the compiler-builtins is or isn't in use. There is another way to check its usage? And what crate is using it? If I knew this I can compile the dependency if the right iOS target.

edit: forgot to put the output in a code block

Compiler-builtins is a part of the standard library which is shipped in precompiled form with rustc.

I can be wrong but this way how compiler-builtins is shipped with rustc looks like a core part of the compiler, not being easy to change, right?

I'm thinking how I can circunvent this issue for now, maybe downgrade the compiler version to a older one that compile with the iOS target that I need or compile everything (compiler-builtins + rustc) by myself and compile the project with it. Any of these solutions would work?

If you are using nightly, you can use IPHONEOS_DEPLOYMENT_TARGET=13.0 cargo build -Zbuild-std=std --target=aarch64-apple-ios to rebuild the standard library including compiler-builtins with the lower deployment target.

I think this is a duplicate of #128419, which was fixed in #133092. Please try the latest nightly? Then the pre-compiled files should have the version 10.0.

Otherwise, as @bjorn3 said, if you want all files to have the same deployment target (usually unnecessary), you will need -Zbuild-std.

With the -Zbuild-std=std worked, thank you everyone 😁 . I think that we can close the issue.
