x86용 먼저(강력한 범용 컴파일러 환경 보유한 우분투를 위해~) sudo apt install libgmp3-dev

ARM 용

export CC=arm-none-eabi-gcc

wget https://gmplib.org/download/gmp/gmp-6.2.1.tar.xz
tar xf gmp-6.2.1.tar.xz
cd gmp-6.2.1

 

./configure --host=arm-none-eabi --prefix=/home/ubuntu/arm/install/gmp ABI=32
make
make install

 

하다보면 결국 알게 된다.

걍... ARM칩 쓰는 맥 M1 을 써야 한다는 것을...
