RT-Thread添加软件包编译出现uint8_t uint16_t uint32_t size_t NULL未定义错误解决方法

描述：
RT-Thread添加软件包会出现uint8_t uint16_t  uint32_t size_t未定义
大致出错内容,如下:

原因：
RT-Thread定义数据类型，使用rt前缀，如rt_uint8_t rt_uint16_t rt_uint32_t rt_size_t等
而开源代码是的大家常用，标准C库定义的uint8_t uint16_t uint32_t size_t数据类型
RT-Thread移植未改过来数据类型定义，头文件也没有加

解决方法：
添加头文件
#include <stdint.h>
#include <stddef.h>

当然添加上面的头文件,不能解决所有问题,像这个问题,就要自己在代码里找了. RT-Thread Studio 方法: 双击错误内容, 在源码里选中这个变量,cltr+双击,定位到定义的位置, 把对应的的头文件加上即可.

千万不要像图中说的,删除掉,这样会影响功能的.

如果还找到定义头文件, 可以临时,注释掉, 让编译通过,也不能删除掉哦.
还有个方法, 没定义的话,自己定义一下, 也可以的. 不过这样话, 也有风险, 原本定义过的, 再定义会出错:重复定义.

还有很可能是配置时,少加载了驱动 \BSP\软件功能包, 这个方法比较复杂, 具体问题要具体分析. 要了解整个开源项目代码结构,相关依赖项目. 这种问题, 网上找答案, 或我们谷动谷力\RT-Thread\电子发烧友....等发贴资咨询. 也可以私信我们.

建议：
RT-Thread官可以统一用标准C库定义的uint8_t uint16_t uint32_t size_t数据类型, 使用我们的代码更有通用性。
大家写代码也用标准C库定义的uint8_t uint16_t uint32_t size_t数据类型，不用使用rt前缀，如rt_uint8_t rt_uint16_t rt_uint32_t rt_size_t NULL等

解决方法, RT-Thread, 编译错误, uint8_t, uint16_t, uint32_t, size_t, NULL
