Cross Compiling 環境設定 (MAC)

目前自己的作法是，採用ubuntu的docker

然後安裝該裝的cc工具：

Operating System	Architecture	Needed package(s)
Linux	armhf	gcc-arm-linux-gnueabihf
		libc6-dev-armhf-cross
Linux	arm64	gcc-aarch64-linux-gnu
		libc6-dev-arm64-cross
Linux	i386	gcc-multilib
		libc6-dev-i386
		linux-libc-dev:i386
Windows	amd64	gcc-mingw-w64-x86-64
Windows	i386	gcc-mingw-w64-i686

 

然後就可以輕鬆build了...

附註：

對於mips平台(例如MTK7688)

就尋找gcc-mips / libc6-dev-mips...

具體看你的mips平台支援哪種 (Linux下用uname -a看一下)

更新：ARM系列與X86-64系列的，Mac下直接安裝套件就好
https://github.com/osx-cross/homebrew-arm
https://github.com/messense/homebrew-macos-cross-toolchains

brew tap messense/macos-cross-toolchains
# install x86_64-unknown-linux-gnu toolchain
brew install x86_64-unknown-linux-gnu
# install aarch64-unknown-linux-gnu toolchain
brew install aarch64-unknown-linux-gnu

然後在/usr/local/bin 查一下要用的cc

GOOS=linux GOARCH=arm64 GOARM=7 CGO_ENABLED=1 CC=aarch64-unknown-linux-gnu-cc go build
