Can you include more information? So this is on Mac M1? What were you doing when this message came up? Can you include the entire log?

What's your rust version? Can you compile other Rust code? (see https://blog.rust-lang.org/2020/11/27/Rustup-1.23.0.html )

secp256k1 = {version = "0.20.1", features = ["std", "recovery"] }

It is in Mac M1.

rustc --version

It build successfully , and I can compile other Rust code:

$cargo build
    Finished dev [unoptimized + debuginfo] target(s) in 0.32s

It is ok！

But i run a test:

cargo test --package xxxxx_crypto --lib -- xxxx::xxx::xxxx --exact --nocapture'

error: linking with `cc` failed: exit code: 1

[elichai]

hmmmm, that won't be easy to debug without an actual mac M1 (are there VMs/qemus of it?)
Can you try these:

1. RUSTFLAGS=-Cembed-bitcode=no cargo test.
2. Building libsecp itself + running the tests(https://github.com/bitcoin-core/secp256k1).
3. Can you try testing other popular FFI crates? (like librocksdb or git2-rs with the zlib-ng-compat feature)

[real-or-random]

The three tests are interesting but in the end I suspect the problem needs to be fixed in cc. This issue here looks relevant: rust-lang/cc-rs#542

[apoelstra]

New versions of cc are incompatible with Rust 1.29 so unfortunately this means we won't be able to hit our MSRV target on the M1.

[real-or-random]

Indeed, but I wonder how important this is on MacOS (e.g., we arrived at 1.29 specifically because we were looking at Debian versions...)

[apoelstra]

We arrived at 1.29 because this is mrustc's target.

But I agree, this probably doesn't matter for users of OS X because they are already running scads of completely closed-source software.

[real-or-random]

We arrived at 1.29 because this is mrustc's target.

Oh right. But yeah, it's probably not as important on Mac as it is on Linux.

[fanatid]

It's not possible to build wasm32 target on M1 right now too:

error: failed to build archive: section too large

I have the same compilation error on a 2015 Macbook Pro on Catalina 10.15. So this may not be an M1-specific issue

Are you also targetting webassembly? can you show the output of the compilation?

FWIWI I just ran cargo test successfully on a Macbook Pro 2019 with Big Sur 11.4.

Unfortunately I changed my rustup config and now cannot reproduce the section too large issue. I was trying out BTC-Parachain when I encountered the issue. Now, instead, I get No available targets are compatible with triple "wasm32-unknown-unknown" when I cargo build the whole project, even though building/testing the crate that uses secp256k1 separately works.

No available targets are compatible with triple "wasm32-unknown-unknown"

FWIW, I believe Apple clang does not support wasm targets and produces this message; using Homebrew clang (brew install llvm and putting it in the PATH) resolves this for me, but now I'm hitting the failed to build archive: section too large error (in a different wasm project, on M1, which is what brought me here...)

Note that it's possible to run the x86_64 toolchain on M1:

arch -x86_64 /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
arch -x86_64 /usr/local/bin/brew install llvm
export PATH="/usr/local/opt/llvm/bin:$PATH"

This still gives me failed to build archive: section too large though.

See #254.

You will also need to override the archiver that is being used (AR env variable)!
