Ubuntu arm 交叉编译环境搭建
- Linaro 官网下载：http://releases.linaro.org/components/toolchain/binaries/
选择Linux解压版，gcc-linaro-arm-linux-gnueabihf-4.9-2014.07_linux.tar.xz
目前我在使用（20220308）：gcc-linaro-6.3.1-2017.05-i686_arm-linux-gnueabihf.tar.xz
百度网盘链接：https://pan.baidu.com/s/1FB_kawsPtM534pp-9wnbZA
提取码：v5hj - 解压
cd 解压目录
xz -d gcc-linaro-arm-linux-gnueabihf-4.9-2014.07_linux.tar.xz
tar -xvf gcc-linaro-arm-linux-gnueabihf-4.9-2014.07_linux.tar - 设置环境变量
vi ~/.bashrc
文件最后添加 export PATH=$PATH:解压目录/gcc-linaro-arm-linux-gnueabihf-4.9-2014.07_linux/bin
source ~/.bashrc - 完了
Arm gcc 各版本的区别：
| multiarch name | syscall ABI | instruction set | endianness | word size | description | spec documents |
| aarch64-linux-gnu | linux | ARMv8 | little | 64 | aarch64 Linux Platform | AAPCS64 (ARM IHI 005A)1 ELF for the ARM 64-bit Architecture2 |
| aarch64_be-linux-gnu | linux | ARMv8 | big | 64 | aarch64 Linux Platform | AAPCS64 (ARM IHI 005A)1 ELF for the ARM 64-bit Architecture2 |
| aarch64-linux-gnu_ilp32 | linux | ARMv8 | little | 32 | aarch64 Linux Platform | |
| aarch64_be-linux-gnu_ilp32 | linux | ARMv8 | big | 32 | aarch64 Linux Platform | |
| arm-linux-gnu | linux | ARMv7 | little | 32 | Old ARM ABI | APCS (ARM DUI 0041 chapter 9)4 |
| arm-linux-gnueabi | linux | ARMv7 | little | 32 | ARM EABI, soft-float | AAPCS (ARM IHI 0042D)5 ARM GNU/Linux ABI Supplement6 |
| arm-linux-gnueabihf | linux | ARMv7 | little | 32 | ARM EABI, hard-float | AAPCS (ARM IHI 0042D)5 and XXXXX (TBD) |
| armeb-linux-gnueabi | linux | ARMv7 | big | 32 | ARM EABI, soft-float | AAPCS (ARM IHI 0042D)5 ARM GNU/Linux ABI Supplement6 |
| armeb-linux-gnueabihf | linux | ARMv7 | big | 32 | ARM EABI, hard-float | AAPCS (ARM IHI 0042D)5 and XXXXX (TBD) |
| armv8l-linux-gnueabihf | linux | ARMv8 | little | 32 | ARMv8 EABI, hard-float | |
| arm-eabi | Bare-Metal | ARMv7 | little | 32 | ARM EABI, soft-float | |
| armeb-eabi | Bare-Metal | ARMv7 | big | 32 | ARM EABI, soft-float | |
| aarch64-elf | Bare-Metal | ARMv8 | little | 64 | ARMv8 EABI, hard-float | |
| aarch64_be-elf | Bare-Metal | ARMv8 | big | 64 | ARMv8 EABI, hard-float |
问题1：执行 arm-linux-gnueabihf-gcc -v 报错
arm-linux-gnueabihf-gcc: cannot execute binary file: Exec format error
原因1：arm-linux-gnueabihf-gcc 32位，系统Ubuntu 64位
解决1：更换32位Ubuntu系统
20220303备忘：
项目使用了c++11标准以及boost库，arm交叉编译工具链版本从4.9升级至6.3
