invalid type: map, expected a MethodSignature

[AI-Mozi]

Hey! Every time I try to run tests or any other programs this error appears.

Error: builtin exports is broken

Caused by:
    invalid type: map, expected a MethodSignature at line 13 column 14

Is it a known issue or something related to my machine?

Oh, you may need to rebuild the core library by cargo run -- build-corelib

[AI-Mozi]

Thanks, that was it. Now I have to deal with other errors 😅 Like failed to run custom build command for 'bdwgc-alloc v0.6.0' when doing cargo build in skc_rustlib Sometimes I get sick of mac..

[AI-Mozi]

Oh, I found why. It's bdwgc-alloc = { version = "0.6.0", default-features=false, features = ["cmake"] } When i change it to { version = "0.6.0" } only its working Is it a big deal to remove default-features and features?

[yhara]

The default-features=false, features = ["cmake"] part is introduced to support Windows. So could you try brew install cmake?

[AI-Mozi]

I have cmake installed :/

cmake --version
cmake version 3.26.3

[AI-Mozi]

This is the whole message

According to the log,

1. cargo tried to build bdwgc-alloc

2. bdwgc-alloc needs bdwgc, so tried to build it with cmake

3. cmake looked for a working C compiler and tried to compile a simple test program

4. It failed with this error:

    ld: in '/opt/homebrew/opt/llvm@12/lib/libunwind.dylib', building for macOS-x86_64 
    but attempting to link with file built for macOS-arm64

Are you using Rosetta2 on M1 mac?

[AI-Mozi]

Yup

[yhara]

Maybe you need to run brew install llvm@12 and cargo run -- build-corelib both on Rosetta2, or both without Rosetta2. I have not installed Rosetta2 so this is my guess though

[AI-Mozi]

I've got it installed on both.. For now I can stay with autotools on my local machine, but I wouldn't close this issue, maybe there will be someone with similar problem :D
