Yeah I found suggestions like that. But how does that work then? Does that need to be the lib compiled for the target (mips) or the machine I'm cross compiling on (darwin)?
Think I miss some knowledge here :) Sander On 22 Jul 2017, at 19:10, Ian Lance Taylor <i...@golang.org> wrote: > On Sat, Jul 22, 2017 at 4:41 AM, Sander van Harmelen <san...@xanzy.io> wrote: > Thanks Ian!

Guessing a bit here… Any pointers on how to solve this? Something like CGO_LDFLAGS="-lusb", with perhaps a -L option to the directory where the library exists.
