cgo從amd64（linux）交叉編譯到arm64（linux）

Question

我試圖使用基於arm64的“ amd64”構建“ arm64”架構的go代碼。 使用共享庫構建go代碼時，出現以下錯誤。 有人可以幫我嗎？

Go版本：go1.10.3 linux / amd64

gcc版本：gcc版本7.3.0（Ubuntu 7.3.0-21ubuntu1〜16.04）

去env：

GOARCH="arm64"
GOHOSTARCH="amd64"
GOHOSTOS="linux"
GOOS="linux"
CGO_ENABLED="1"

錯誤：建立hello.go

# runtime/cgo

驗證碼：

package main
/*
#cgo CFLAGS: -I./cgolang/include
#cgo LDFLAGS: -L./cgolang/lib  -laxxxxxx
#include "axxxxxx.h"
*/
import "C"
import "fmt"

func main() {
fmt.Printf("hello, world\n")
}

Answer 1

我像這樣#cgo LDFLAGS鏈接了數學庫：-L./cgolang/lib -lpthread -lm

那對我有用。 如果您的共享庫是由第三方提供的，請讓他們幫助您

Answer 2

env CGO_ENABLED=1 GOOS=linux GOARCH=arm64 CC=/path/to/your/arm64/gcc go build hello.go
