macos release not self-contained -- requires llvm installed on the system

[hasenj]

Context

Downloading the macos build from this page:

https://github.com/odin-lang/Odin/releases/tag/dev-2021-06

The assumption here is that someone who just wants to use the language, and not build it from source.

• Operating System: macOS
• Please paste odin version output: N/A. See below. Release number mentioned above.

Expected Behavior

Compiler works out of the box.

Current Behavior

• The executable does not have the executable permission

  • The user must manually run chmod u+x odin

• The executable is not self-contained. It requires a specific version of llvm to be installed in a specific location

$ odin
dyld: Library not loaded: /usr/local/opt/llvm@11/lib/libLLVM-C.dylib
  Referenced from: /Users/hasenj/odin/odin
  Reason: image not found
Abort trap: 6

$ odin version
dyld: Library not loaded: /usr/local/opt/llvm@11/lib/libLLVM-C.dylib
  Referenced from: /Users/hasenj/odin/odin
  Reason: image not found
Abort trap: 6

Steps to Reproduce

Please provide detailed steps for reproducing the issue.

1. Have a macOS system without llvm installed
2. Download the release and unzip it to a reasonable location, e.g. ~/odin and make sure it's added to the $PATH variable
3. Invoke the odin command

I suspect it would make sense to have a llvmlib directory in which this library goes ideally setup with rpath‘s so that it doesn’t require a fixed position for the library.

in case anyone else runs across this issue trying out Odin, you can fix it by doing the following:

Download version of LLVM Odin is using

brew install llvm@11

add to PATH

echo 'export PATH="/usr/local/opt/llvm@11/bin:$PATH"' >> ~/.zshrc

add execute permission to Odin

chmod +x odin

Profit

./odin run examples/demo/demo.odin -file

In case anyone is trying this in 2023, I was trying to install Odin in my M2 Macbook with asdf and asdf-odin.

I got an error saying that a llvm@11/lib/libLLVM-C.dylib file was needed. I had the file, but the error said it was (mach-o file, but is an incompatible architecture (have 'arm64', need 'x86_64')).

That's when I realized that the GitHub releases don't currently include arm64 builds, but maybe that'll change someday? 😄

Sooooo, for now I'll just have to compile Odin from source on my arm64 machine.

Since the 2024-03 macOS releases are now self contained, it now also supports arm64 so this can be closed.
