Please attach the crash log so that we can see why it's crashing.

[sainnhe (Sainnhe Park)]

Very strange, the process get killed in zsh but if I use lldb to launch it, then it won't get killed and entered into REPL environment as expected.

I tried to search for related issues in their repository and found that the possible reason might be

“Julia-1.2” can’t be opened because Apple cannot check it for malicious software.

But I didn't see such prompt window when the process get killed. And I also tried to navigate to /opt/local/bin and right click the binary and select open, still no success.

Related issues here:

Any ideas?

Crash log

[kenniskoldewyn (Kennis Koldewyn)]

See attached crash log. TLDR; SIGKILL (Code Signature Invalid). (I built with +gcc11, so it's not gccdevel, and I'm on MacOS 12.1, but I'm guessing it's the same problem.)

Same issue; codesign shows the signature for libjulia is borked:

> codesign --verbose=4 /opt/local/lib/libjulia.1.7.dylib                                                                                 
/opt/local/lib/libjulia.1.7.dylib: invalid signature (code or signature have been modified)
In architecture: arm64

I worked around it by resigning (adhoc) the .dylib:

> codesign -s - /opt/local/lib/libjulia.1.7.dylib

This happened with a source build as well, so I'm guessing something is modifying the dylib after (linker) signing as part of the build.

[i0ntempest]

The portfile calls install_name_tool after destroot on the binary which might be the reason of this. We could adhoc sign the dylib and binary after destroot, like what I'm doing with my qbittorrent ports.
Shall I add it in?

julia: manually fix code signature on arm
