What version of Go are you using (go version)?

go version go1.6.3 windows/386

What operating system and processor architecture are you using (go env)?

set GOARCH=386
set GOBIN=
set GOEXE=.exe
set GOHOSTARCH=386
set GOHOSTOS=windows
set GOOS=windows
set GOPATH=E:\go
set GORACE=
set GOROOT=C:\Program Files\Go
set GOTOOLDIR=C:\Program Files\Go\pkg\tool\windows_386
set GO15VENDOREXPERIMENT=1
set CC=gcc
set GOGCCFLAGS=-m32 -mthreads -fmessage-length=0
set CXX=g++
set CGO_ENABLED=1

What did you do?

%GOPATH%\bin\gomobile.exe init

What did you expect to see?

E:\go\bin\gomobile.exe: go install -gcflags=-shared -ldflags=-shared -pkgdir=E:\go\pkg\gomobile/pkg_android_arm64 std failed: exit status 2

your computer's system information to see whether you need a x86 (32-bit) or x64 (64-bit) version of the program, and then contact the software publisher.

Go itself supports XP and newer. This error is coming from the Android NDK that gomobile uses. What Windows are you on? XP 32-bit?

This is unfortunate but we cannot support a version of windows unless the NDK toolchain is supported on it.

@crawshaw: From the error message I was wondering if what actually happened is we incorrectly downloaded the 64-bit NDK on a 32-bit arch.

I've got 32-bit Vista.

I was wondering if what actually happened is we incorrectly downloaded the 64-bit NDK on a 32-bit arch.

What is actually happening gomobile downloads gomobile-ndk-r12b-windows-x86.tar.gz wich contains both 32-bit (clang_32.exe) and 64-bit (clang.exe) versions of clang:

But gomobile always copy clang.exe to be used on both 32-bit and 64-bit versions of windows.
