Could not open library 'sodium': dlopen(sodium, 5): image not found. (LoadError) on Apple Silicon M1 #216

Hey there,

I'm trying to get rbnacl to function on my M1, but I am hitting the following error message:

While at first, this looks like I don't have libsodium installed, I want to point out that I do have it installed via brew.

ole@Oles-MBP-2 test % brew test libsodium          
==> Testing libsodium
==> /usr/bin/clang test.c -I/opt/homebrew/Cellar/libsodium/1.0.18_1/include -L/opt/homebrew/Cellar/libsodium/1.0.18_1/lib -lsodium -o test
==> ./test

Any pointers or workarounds would be appreciated šŸ‘

Haha, oh joy, this is like the third M1-related issue I've seen today šŸ˜‚

The other ones were C extensions with the system ruby so I'm not really sure what the state of things is with FFI on the M1.

Are you using the system ruby or one you installed with e.g. ruby-install? The latter seems way less problematic for C extensions.

OleMchls commented 3 years ago

@tarcieri thanks for your prompt reply. I am afraid the M1 won't go away that fast :D That ruby comes from asdf, which I assume builds it using ruby-build.

tarcieri commented 3 years ago

Huh, interesting. I wonder if there are any relevant upstream issues on FFI itself.

Can you locate the actual .dylib on your filesystem and check that it's named one of the things FFI is trying:

Could not open library 'libsodium.dylib': dlopen(libsodium.dylib, 5): image not found.
Could not open library 'libsodium.so.18': dlopen(libsodium.so.18, 5): image not found.
Could not open library 'libsodium.so.18.dylib': dlopen(libsodium.so.18.dylib, 5): image not found.

What's the best way to locate it? That's not my particular area of expertise šŸ˜…

OleMchls commented 3 years ago

I found those files

/opt/homebrew/lib/libsodium.dylib
/opt/homebrew/Cellar/libsodium/1.0.18_1/lib/libsodium.dylib

There are even more:

ole@Oles-MBP-2 dnsimple % ls -lhas /opt/homebrew/lib/libsod*  
0 lrwxr-xr-x  1 ole  admin    51B Feb  4 23:04 /opt/homebrew/lib/libsodium.23.dylib -> ../Cellar/libsodium/1.0.18_1/lib/libsodium.23.dylib
0 lrwxr-xr-x  1 ole  admin    44B Feb  4 23:04 /opt/homebrew/lib/libsodium.a -> ../Cellar/libsodium/1.0.18_1/lib/libsodium.a
0 lrwxr-xr-x  1 ole  admin    48B Feb  4 23:04 /opt/homebrew/lib/libsodium.dylib -> ../Cellar/libsodium/1.0.18_1/lib/libsodium.dylib

But I assume I am missing the bit that connects ruby to those, I assume that is .dylib? I just don't know what's next

tarcieri commented 3 years ago

Those look fine, so this seems like it might be some sort of FFI (or homebrew, or FFI + homebrew) issue on the M1. Unfortunately I can't help debug.

@tarcieri thanks for putting in the effort. It gave me the first pointers <3
