ubuntu x86_64架构的编译 aarch64架构的程序

1.安装arm64的gcc g++

sudo apt install gcc-aarch64-linux-gnu g++-aarch64-linux-gnu

2.要修改makefile 和对应的链接的库都要是对应架构的目录和库

bash 复制代码

# ==============================================================================
# Created By QMCY @20260730
# ==============================================================================
# 默认值设置 (可以在命令行通过 make VAR=value 覆盖)

IO ?= NIO
MQTT ?=no
VERSION ?=V3
SDK ?= no
PARSER ?=JS_LEDV3
TOKEN ?=         yes
TYPE ?= LED

SYNC ?= no
CLIENT ?= no
REDIS ?= no
WS ?=no

CC ?= g++

# x86_64 aarch64 armv7l
ARCH ?= $(shell uname -m)

# 2. 根据架构映射到库目录名

顺带一个freetype的编译脚本

bash 复制代码

./configure --prefix=/home/qmcy/freetype-2.13.3/install \
  --without-png --without-bzip2 --without-brotli --without-zlib
