Siu*_*ji- 6 android cross-compiling go cgo 

adb shell

0. Go(Golang)来源

package main

import (
    "fmt"
)

func main() {
    fmt.Println("Hello, world!")
}

1A.构建命令

$ CGO_ENABLED=0 GOOS=android GOARCH=arm GOARM=7 go build .

1B.输出(换行重新排列以防止滚动条)

# github.com/asukakenji/cross
warning: unable to find runtime/cgo.a
/usr/local/go/pkg/tool/darwin_amd64/link: running clang failed: exit status 1

1C.再一次构建命令

以下命令给出相同的结果:

$ env CGO_ENABLED=0 GOOS=android GOARCH=arm GOARM=7 go build .

2.构建命令(详细)

"-v"
$ CGO_ENABLED=0 GOOS=android GOARCH=arm GOARM=7 go build \
      -x -ldflags "-extldflags -v" .

go buildclangXcode

3A.构建命令(成功,但......)

$CC
$ CGO_ENABLED=0 GOOS=android GOARCH=arm GOARM=7 \
      CC=/path/to/arm-linux-androideabi/bin/clang go build .

arm-linux-androideabimake_standalone_toolchain.pymake-standalone-toolchain.sh

3B.输出

cross
# github.com/asukakenji/cross
warning: unable to find runtime/cgo.a

adb pushadb shell

我的问题

$ CGO_ENABLED=0 GOOS=linux GOARCH=amd64 go build .

谢谢!
