ubuntu x86_64 or linux
若要編譯一包 open source 通常會使用到
./configure --build=xxx-linux-gnu --host=xxx-linux-gnu --target=xxx-linux-gnu
這裡給出幾個解釋 讓大家真正了解定義

CHAPTER 11 COMPILING GCC P.233
The build system is the machine on which you build GCC;
the host system is the machine on which the completed compiler will run;
and the target system is the machine for which the compiler will generate code.

GCC source

AR AS LD binutils source

I have a PowerPC machine making a compiler that you will run on an x86
machine that will make binaries that run on an ARM.
That makes the PPC the build,
the x86 the host,
and the target is the ARM

./configure --build=i386-linux --host=powerpc-linux --target=powerpc-linux
利用i386-linux(--build)的編譯器對gcc進行編譯
編譯出來的gcc運行在powerpc-linux(--host)
這個gcc用來編譯能夠在powerpc-linux(--target)運行的代碼。

This script will guess the type of the 'build' machine.

Note: NetBSD doesn't particularly care about the vendor
portion of the name. We always set it to "unknown".
//
EX: ./configure --build=x86_64-unknown-linux-gnu --host=x86_64-linux-gnu
--target=x86_64-linux-gnu
build:
編譯 GCC source 與 編譯 AR AS LD source
是在 x86_64 未知製造商的 linux 系統
host:
GCC & AR AS LD 在 86_64-linux 執行 hello_world.c 的編譯
target:
hello_world 在 CPU 為 arm64 的系統下執行
