arm64 support

[brennanjl]

When running this, I am getting the following warning:

ld: warning: ignoring file ~/.wasmedge/lib/libwasmedge.dylib, building for macOS-arm64 but attempting to link with file built for macOS-x86_64

I then get a long stack trace, and the errors:

ld: symbol(s) not found for architecture arm64 clang: error: linker command failed with exit code 1 (use -v to see invocation)

AFAIK this means that I have to rebuild this library for my architecture. I can't seem to find where to do this in the docs, is this supported?

Update: it seems this was a known issue a while ago, as found here: https://github.com/second-state/WasmEdge-go/issues/18

The issue still occurs for me.

Hi @brennanjl Thanks for raising this issue. How did you install the wasmedge library? We provide both aarch64 and x86_64 libraries for macOS. But the error message shows that ld is trying to link with different arch versions.

I installed by running curl -sSf https://raw.githubusercontent.com/WasmEdge/WasmEdge/master/utils/install.sh | bash -s -- -e all, as found here: https://wasmedge.org/book/en/quick_start/install.html.

I am able to use the tool just fine; if I have a wasm file called main.wasm, I can run wasmedge main.wasm and it works as expected. The issue seems to be when using this SDK.

It could be a local configuration issue for CGo, I am unsure.

I've taken a look through all of the files in ~/.wasmedge/lib directory and they all seem to be built for x86_64

Edit: It also seems that my wasmedge executable is for x86_84. I am not sure how it is running on my machine (I guess using Rosetta 2?), but this could be why it is not working in cgo.

Got it working. Here's a recap for anyone else who might run into this:

• The bash command for installing in the quickstart docs installed the x86_64 version (at least for me).
• Mac will run this fine in the Terminal using Rosetta 2.
• Golang will NOT compile this using CGO, since the dylibs are for x86_64.
• If you manually install the arm64 version, it works as expected.

Hi @brennanjl Could you try to run the installer with -D? Because I cannot reproduce the result on my M2 MacBook.

Here is the command I used:

$ curl -sSf https://raw.githubusercontent.com/WasmEdge/WasmEdge/master/utils/install.sh | bash -s -- -D
