ops giving unhelpful error msg for missing linked lib on osx

[eyberg]

ops currently gives a very un-helpful error msg if it can't find a library that it is trying to load

➜  l ops run test
panic: failed building manifest: file does not exist

goroutine 1 [running]:

it should tell the user what file it is trying to load and I don't think this error wrapping lib that's in the codebase is very useful at all and should prob just be yanked

I think the error is that findlib function of lepton/ldd_darwin.go

I can work on this. Can you elaborate how to reproduce this?

Started playing around with OPS earlier today and having this issue as well. I'm on a m1 with MacOS 12.1, just installed OPS via curl https://ops.city/get.sh -sSfL | sh.

❯ ops version
Ops version: 0.1.29
Nanos version: 0.0

When I try to either ops run my-go-binary or ops image create ... I get a similar error.

❯ ops run main

Any hints on which library might be missing would be greatly appreciated.

@geoah we're working on a fix for this but if you copy your binary to a linux and run 'ldd my-go-binary' one of the libraries listed in that output it's probably not being found on your mac and will need to be copied down and put into the location it expects - on linux we parse all this output and auto-include the libraries found; typically this isn't a problem w/go unless you are doing something with possibly a cgo dependency

@eyberg thank you, building my binary with CGO disabled doesn't result in an error.
