cyme on Apple silicon

[applebait]

Probably I need to manage how to link libusb to where cyme is looking for it… I'm getting this output when trying "cyme" or "cyme --force-libusb":

dyld[20594]: Library not loaded: /usr/local/opt/libusb/lib/libusb-1.0.0.dylib Referenced from: <5D31FBC5-C545-38BC-A8C4-49BD63503AA7> /opt/homebrew/Cellar/cyme/1.2.7/bin/cyme Reason: tried: '/usr/local/opt/libusb/lib/libusb-1.0.0.dylib' (no such file), '/System/Volumes/Preboot/Cryptexes/OS/usr/local/opt/libusb/lib/libusb-1.0.0.dylib' (no such file), '/usr/local/opt/libusb/lib/libusb-1.0.0.dylib' (no such file), '/usr/local/lib/libusb-1.0.0.dylib' (no such file), '/usr/lib/libusb-1.0.0.dylib' (no such file, not in dyld cache) zsh: abort cyme --force-libusb

Hmm, it looks like this is due to libusb not being installed (brew install libusb) I added it as a depends_on so not sure what's going on.

If you do, brew info cyme do you get:

==> Dependencies
Required: libusb ✔

As part of the output?

[tuna-f1sh]

I think this is as you say, due to libusb not being where expected

export DYLD_PRINT_LIBRARIES=1                                                                                                                                 
cyme

Is there anything in ls -la /usr/local/opt/libusb/lib ? There should be a symbolic link created by Homebrew:

ls -la /usr/local/opt/ | grep 'libusb'

Hello. I ran into the same issue on my Apple Studio M1 Max. I have libusb installed:

➜ brew info cyme
==> tuna-f1sh/taps/cyme: stable 1.2.7
List system USB buses and devices; a modern and compatiable `lsusb`

zsh completions have been installed to:
  /opt/homebrew/share/zsh/site-functions

and get the same error when I run cyme:

➜ cyme

zsh: abort      cyme

Looks like libusb is not properly linked:

➜ ls -la /usr/local/opt/libusb/lib
ls: /usr/local/opt/libusb/lib: No such file or directory

I also tried running brew unlink libusb && brew link libusb but it doesn't help. The *.dylib file is present in /opt/homebrew/Cellar/libusb/1.0.26/lib:

➜ ls -la /opt/homebrew/Cellar/libusb/1.0.26/lib | grep libusb
-r--r--r--@  1 maciejkobus  admin  177440 19 lut 00:53 libusb-1.0.0.dylib

lrwxr-xr-x@  1 maciejkobus  admin      18 10 kwi  2022 libusb-1.0.dylib -> libusb-1.0.0.dylib

Thanks for the extra info. It looks like ARM binaries and libs are stored in a different place: https://apple.stackexchange.com/a/410829

I'll have to look into it a bit more to figure out what's going on and how tools account for both. It might be that the build workflow needs to create a binary for macOS x86 and ARM. Any extra digging by you guys would be helpful since I don't have a Apple silicon to test with.

[webhdx]

If you have anything to test just ping me. I love the project and since I mess with USB devices a lot I'd greatly appreciate being able to use it on Apple Silicon :)

[webhdx]

BTW I can confirm libusb-1.0.0.dylib is present in /opt/homebrew/lib/ on my Mac.

[tuna-f1sh]

Can you try this cross-compiled aarch64? cyme-aarch64-apple-darwin.zip - I'll look at adding a universal binary if it does.

It might also work if you export DYLD_LIBRARY_PATH=/opt/homebrew/lib before running the current release.

[webhdx]

Yup precompiled binary works. Great job. Having native aarch64 binary will be preferred over x86 Rosetta translated one. Hope this is added to homebrew soon.

Sorry for being out of communication… And a million thanks to both of you for managing the fix!
