Linux arm 交叉编译（1）——常用的some tools

交叉编译语法

参考链接：
https://blog.youkuaiyun.com/liufuchun111/article/details/81509651

1、export

CROSS_COMPILE

export CROSS_COMPILE=../prebuilts/gcc/linux-x86/aarch64/gcc-arm-10.3-2021.07-x86_64-aarch64-none-linux-gnu/bin/aarch64-none-linux-gnu-

PATH

export PATH=../prebuilts/gcc/linux-x86/aarch64/gcc-arm-10.3-2021.07-x86_64-aarch64-none-linux-gnu/bin:$PATH

SYSROOT

2、./configure

–build
用来指定执行代码编译的主机，一般由config.guess自动配置

例如：
--build=x86

–host
用来指定编译出来的二进制程序所执行的主机环境

例如：
--host=arm64

–prefix
用来指定程序编译完成后安装的路径

例如：
--prefix=$PWD/install

–sysroot
用于指定逻辑工作路径

3、make install安装路径

1.Makefile工程
make install DESTDIR=/path
 
2.QT工程
make install INSTALL_ROOT=/path
 
3.ninja工程
DESTDIR=/path ninja -C . install
 
注意：./path为绝对路径

some tools的编译

1、iperf打流工具

本示例适用平台：ok4418

编译方法

克隆源码
git clone https://github.com/esnet/iperf.git

交叉编译
mkdir install
./configure --host=arm-linux CC=arm-cortex_a9-linux-gnueabi-gcc CFLAGS=-static CXX=arm-cortex_a9-linux-gnueabi-g++ CXXFLAGS=-static --prefix=$PWD/install
make;make install

用法
TBC

2、phytool

本示例适用平台：rk3399
网络phy芯片调试工具。
编译方法

克隆源码
git clone https://github.com/wkz/phytool.git

加载环境变量
source envsetup.sh

编译
make

用法

$ ./phytool
Usage: phytool read  IFACE/ADDR/REG
       phytool write IFACE/ADDR/REG <0-0xffff>
       phytool print IFACE/ADDR[/REG]

Clause 22:

ADDR := <0-0x1f>
REG  := <0-0x1f>

Clause 45 (not supported by all MDIO drivers):

ADDR := PORT:DEV
PORT := <0-0x1f>
DEV  := <0-0x1f>
REG  := <0-0xffff>

Examples:
       phytool read  eth0/0:4/0x1000
       phytool write eth0/0xa/0 0x1140
       phytool print eth0/0x1c

The `read` and `write` commands are simple register level
accessors. The `print` command will pretty-print a register. When
using the `print` command, the register is optional. If left out, the
most common registers will be shown.

ieee-phy: id:0x001cc915

   ieee-phy: reg:BMCR(0x00) val:0x1140
      flags:          -reset -loopback +aneg-enable -power-down -isolate -aneg-restart -collision-test

3、memtester

本示例适用平台：t507
内存压力测试工具。

编译方法
依托t507的sdk，使用bulidroot添加memtester到文件系统。
添加编译配置

make menuconfig

重现编译buidlroot，获取编译的可执行文件

用法

memtester size times

4、lz4

压缩工具，一般镜像编译完成后的压缩打包会用到。

编译方法

git clone https://github.com/ScottImpGreen/lz4.git
make install
sudo make install

用法

export PATH=/usr/local/bin:$PATH
