Hello! Does anyone know how to compile go "hello world" binary for armv5
processors? Mine setup fails all the time for armv5 and works on armv7.
export TOOLCHAIN=$PWD/tools/
export NDK=~/Library/Android/sdk/ndk-r16b/
$NDK/build/tools/make_standalone_toolchain.py --arch arm --api 14
--install-dir $TOOLCHAIN
CC="$TOOLCHAIN/bin/arm-linux-androideabi-clang -march=armv5 -mfpu=vfpv2
-mfloat-abi=soft -mno-thumb" CGO_ENABLED=1 GOOS=android GOARCH=arm GOARM=5
go build main.go
*main.go*
package main
import "fmt"
func main() {
fmt.Println("123")
}
I dig around a bit. And got answer from google ARMV5 is supported by Golang
(https://github.com/golang/go/issues/29729) but it is still not working.
How I understand golang creates binary blobs which linked into resulting
binary. If we assume blobs are ok, and toolchain getting correct arguments
to produce final binary file here should be no problems. But something is
wrong. If we break build process step by step then we will see that last
clang call producing '_cgo_.o' file size of 31072, but resulting final
'main' binary is 1957471 bytes. Who is making this final step and probably
with incorrect arm archeticture flags?
