macos support about tch-rs HOT 4 CLOSED

--allow-shlib-undefined option is not defined on mac
remove it or you will get "note: ld: unknown option: --allow-shlib-undefined" error
simply remove it from .cargo/config, it work for me.
I don't know if there is a better option.

Thanks for pointing this out. I added this --allow-shlib-undefined flag in order to get things to compile on some gpu configurations. Things have changed a bit since then so maybe it's not needed any more, I'll give it a try and remove the flags if not necessary.
Were you able to run the tests via cargo test, it would be pretty amazing if it just end up working with this small tweak on macos.

@LaurentMazare I think I can pass cargo test. It works well for me.

Fyi I just tweaked the cargo config file so that the --allow-shlib-undefined flag only applies to linux - this should hopefully make the default build work on mac.
