usermod -a -G sudo xxxxxusermod -a -G sudo xxxxx1、进入uboot修改源码
vim include/configs/lx2160a_common.h最后增加
/*Begin:add by zhaobaoxing for env*/
#define CONFIG_SYS_MMC_ENV_DEV 0
#define CONFIG_ENV_SIZE 0x2000 /* 8KB */
#define CONFIG_ENV_SECT_SIZE 0x20000
#define CONFIG_ENV_OFFSET 0x500000
#define CONFIG_ENV_ADDR (CONFIG_SYS_FLASH_BASE + CONFIG_ENV_OFFSET)
/*End:add by zhaobaoxing for env*/
2、修改fw_env.config文件
# Configuration file for fw_(printenv/setenv) utility.
# Up to two entries are valid, in this case the redundant
# environment sector is assumed present.
# Notice, that the "Number of sectors" is not required on NOR and SPI-dataflash.
# Futhermore, if the Flash sector size is omitted, this value is assumed to
# be the same as the Environment size, which is valid for NOR and SPI-dataflash
# Device offset must be prefixed with 0x to be parsed as a hexadecimal value.
# NOR example
# MTD device name Device offset Env. size Flash sector size Number of sectors
#/dev/mtd1 0x0000 0x4000 0x4000
#/dev/mtd2 0x0000 0x4000 0x4000
# MTD SPI-dataflash example
# MTD device name Device offset Env. size Flash sector size Number of sectors
#/dev/mtd5 0x4200 0x4200
#/dev/mtd6 0x4200 0x4200
# NAND example
#/dev/mtd0 0x4000 0x4000 0x20000 2
# On a block device a negative offset is treated as a backwards offset from the
# end of the device/partition, rather than a forwards offset from the start.
# Block device example
/dev/mmcblk0 0x500000 0x2000
#/dev/mmcblk0 -0x20000 0x20000
# VFAT example
#/boot/uboot.env 0x0000 0x4000
# UBI volume
#/dev/ubi0_0 0x0 0x1f000 0x1f000
#/dev/ubi0_1 0x0 0x1f000 0x1f000
# UBI volume by name
#/dev/ubi0:env 0x0 0x1f000 0x1f000
#/dev/ubi0:env-redund 0x0 0x1f000 0x1f000

1、查看磁盘使用大小：
df -h
2、查看目录占用大小
cat /proc/kallsyms grep fib4 rule default
1、下载源文件
http://ftp.gnu.org/pub/gnu/ncurses/
Tags · mirror/ncurses (github.com)
Ncurses project files : Ncurses (launchpad.net)
2、加压并配置
./configure --prefix=/usr/aarch64-linux-gnu --host=aarch64-linux CC=aarch64-linux-gnu-gcc --without-cxx --without-cxx-binding --without-ada --without-manpages --enable-overwrite --without-debug --without-tests --with-shared --without-tests --without-progs
3、编译并安装
make&&make installmake cfg all tgt=rom ARCH=mips CROSS_COMPILE=mipsel-linux- DEBUG=-g第一部分：ARCH=mips CROSS_COMPILE=mipsel-linux- DEBUG=-g
ARCH=mips 设置了平台是mips平台
CROSS_COMPILE=mipsel-linux- 设置交叉编译器前缀，在编译时会替换成mipsel-linux-，之所以设置环境变量，一个是方便在这儿不用输入绝对路径，当找不到交叉编译器的时候，需要输入交叉编译器的绝对路径
DEBUG=-g 设置调试信息第二部分：make cfg all tgt=rom
make cfg 是配置
make all
make tgt=rom 在Makefile.inc里可以看到，是生成的二进制文件1、原因
2、解决方法
意思是新的glibc库已经不支持sys_siglist[]，使用strsignal()。
重点方括号变成了圆括号，就是由数组变成了函数。
1、下载并解压
https://github.com/mongodb/mongo-c-driver/releases/download/1.23.4/mongo-c-driver-1.23.4.tar.gz编译环境：Ubuntu 20.04
2、环境配置
sudo apt-get install cmake libssl-dev libsasl2-dev
tar xzf mongo-c-driver-1.23.4.tar.gz
cd mongo-c-driver-1.23.4
mkdir cmake-build
cd cmake-build
