Build fails with "error: implicit declaration of function 'nanosleep'" #32

Closed SCP002 closed 2 years ago

SCP002 commented 2 years ago

On attempt to cross-compile a program with clipboard in dependencies from windows to linux amd64:

Set GOOS=linux
Set GOARCH=amd64
Set CGO_ENABLED=1

go build main.go

Gives:

# runtime/cgo
gcc_libinit.c: In function '_cgo_try_pthread_create':

I don't think it is not possible to do cross-compilation directly. If you really need a compilation environment, it is recommended to use Docker. See https://github.com/golang-design/clipboard/blob/main/Dockerfile as an example.
