I have just started using Rust and find it to be an exciting language. I am compiling code on Mac M1 laptop. However, the executables created are not running on Apple Silicone Macs, though they are running well on M1 and Intel macs. Where is the problem and how can it be solved? Thanks for your help.
This isn't meaningful. M1 is an Apple Silicon CPU. (It's like saying that your x86 code doesn't run on Intel.) Specifically what CPU doesn't your executable run on?
Can you show us the exact commands you have been running and any output that has been printed to the terminal?
Also, if you run
rustc --version --verbose it'll print out a bunch of information including your laptop's "target triple". That'll tell us what type of architecture and OS the Rust compiler is compiling for.
I'm using Rust on an M1 Mac (i.e. apple silicon) right now and haven't had any issues, so the issue might be related to the way Rust was installed or the commands you are running.
I just use command: "cargo build --release"
Okay, so how do you know it won't run? Can you copy/paste all the commands you execute while building the program and running it, as well as the output you get from each command?
There's a good chance all the information people need to troubleshoot this will be printed to the terminal, but by saying "I just use command: cargo build --release" we don't really have much to go on other than "it doesn't work".
You also didn't show the output from
rustc --version --verbose.
I run following commands:
cargo new myappl
cargo add dependency_pkg
I just edit the main.rs file till there are no errors and warnings and the output is ok. Then I just run the command "cargo build --release" and the executable file is built. I find it very elegant.
The output of rustc command is as follows:
$ rustc --version --verbose
rustc 1.68.2 (9eb3afe9e 2023-03-27)
LLVM version: 15.0.6
I copy the executable to other Macs and try to run them by double-clicking the file. Surprisingly, the executables created by above system runs well on Intel macs but not on AppleSilicon macs.
Correction: my mac is MacBook Air Apple M2 and not M1
Usually the problem is that when you migrated macOS from an Intel Mac, you have Intel-only Rust installation migrated, running under Rosetta. But your
rustc --version looks okay, and is seems to be aware of Apple Silicon (Rust calls it
To be 100% sure, you can run
cargo build --target aarch64-apple-darwin --release and it will build ARM-only executables in
Note that Cargo doesn't support making Universal Binaries. To make one, you need
lipo command from Xcode:
cargo build --target aarch64-apple-darwin cargo build --target x86_64-apple-darwin lipo -create target/aarch64-apple-darwin/release/yourexe target/x86_64-apple-darwin/release/yourexe -output yourexe
Yes, it's really surprising. But the real surprise here is that it runs on Intel Mac.
Code which is not specifically signed for the distribution is not supposed to be usable on devices other than where it was built. This is just how macOS works novadays and has nothing to do with Rust, specifically.
P.S. It's not impossible to run unsigned software (or software signed for other Mac), but by default it's forbidden. You can google about ways to disable these checks, they are not that hard to find. And they are not Rust-specific at all.
@kornel : Thanks for very useful commands. They worked well on my system. I will be trying the newly created universal binary on other Macs tomorrow and will post feedback here.
@khimru : If universal binary does not work, I will try to disable the checks.
The universal binary created by lipo command works very well on both types of Mac. Thanks for your help.
