ftdi depends on cgo #17

Closed schmidtw closed 1 year ago

schmidtw commented 1 year ago

Describe the bug The host package depends on periph/d2xx which depends on cgo. https://github.com/periph/d2xx/blob/86eb5ae2a9f0cabc315eff6641cd8aea22df5b6c/d2xx_linux_amd64.go#L5

This dependency should probably be fixed or removed to maintain the No C dependency, doesn’t use cgo. policy.

To Reproduce

  1. Install go compiler on a fresh RPI install. Do not install c compiler.
  2. git clone https://github.com/periph/cmd.git
  3. cd cmd
  4. go build ./...
  5. See error: 
    # periph.io/x/d2xx
cgo: C compiler "gcc" not found: exec: "gcc": executable file not found in $PATH

Expected behavior Build succeeds.

Platform (please complete the following information):

Additional context The ftdi libraries are neat, but probably shouldn't be in the periph projects unless you segment out "here are projects that are related but use cgo".

d2xx depends on cgo only if cgo is enabled. Set the environment variable CGO_ENABLED=0 to not depend on the cgo enabled code. Is this good enough for you?

Yes, I missed that I could do that. Thank you.
