Ubuntu下交叉编译Go1.19.4遇到的问题
I.MX6开发板上没有Go运行环境，需要先编译GO环境源码，本次编译的是Go1.19.4版本，根据网上资料在编译如下步骤的时候出现问题：forlinx@ubuntu:/usr/local/go/src$ sudo GOROOT_BOOTSTRAP=/usr/local/go1.4CC_FOR_TARGET=arm-poky-linux-gnueabi-gcc CXX_FOR_TARGET=arm-poky-linux-gnueabi-g++ CGO_ENABLED=1 GOOS=linux GOARCH=arm GOARM=7 ./make.bash
Building Go cmd/dist using /usr/local/go1.4. (go1.4-bootstrap-20170531 linux/amd64)
go tool dist: cannot invoke C compiler ["arm-poky-linux-gnueabi-gcc"]: exec: "arm-poky-linux-gnueabi-gcc": executable file not found in $PATH
Go needs a system C compiler for use with cgo.
To set a C compiler, set CC=the-compiler.
To disable cgo, set CGO_ENABLED=0.
arm-poky-linux-gnueabi-gcc等编译器都已安装正常
不知道如何下手排查这个问题！！！
交叉编译的时候不用sudo
install 的时候才需要
用sudo 后等于切换一个使用者
PATH里面没有 arm-poky-linux- 的路径了
或是指定 CC_FOR_TARGET & CXX_FOR_TARGET 带上路径
CC_FOR_TARGET=<full_path>/arm-poky-linux-gnueabi-gcc CXX_FOR_TARGET=<full_path>/arm-poky-linux-gnueabi-g++ 感谢，的确是这样原因。不过又出现新的问题了：
GOROOT_BOOTSTRAP=/usr/local/go1.4CC_FOR_TARGET=arm-poky-linux-gnueabi-gcc CXX_FOR_TARGET=arm-poky-linux-gnueabi-g++ CGO_ENABLED=1 GOOS=linux GOARCH=arm GOARM=7 ./make.bash

arm-poky-linux-gnueabi-gcc: error: unrecognized command line option '-m64'
go tool dist: FAILED: /usr/local/go/pkg/tool/linux_amd64/go_bootstrap install std cmd: exit status 2
网络上针对此种问题是：
打开Makefile文件，在 makefile中查找所有的“-m64”，然后删除即可。
可Go源码编译目录下没有makefile文件呀？能否再指导一下
试试下面指令
find . -type f -exec grep -nH -e "\-m64" {} \;
