怎么解决keil中的unknown type name uint8_t

在Keil中，`uint8_t`是一个无符号8位整数类型，它的定义来自于标准C库。如果编译器出现了“unknown type name uint8_t”这个错误，可能是因为编译器不能找到`uint8_t`类型的定义。

解决这个问题的方法是包含stdint.h头文件。stdint.h头文件中定义了各种整型类型，包括`uint8_t`类型。在您的代码中包含这个头文件，就可以使用`uint8_t`类型了。

在Keil中包含stdint.h头文件的方法是在代码中添加以下行：

#include <stdint.h>

这样就可以使用`uint8_t`类型了。

This error usually occurs when the compiler doesn't recognize the data type `uint8_t`. To fix this, you need to include the appropriate header file that defines this type.

In Keil uVision, you can include the `<stdint.h>` header file at the beginning of your source code. This header file defines standard integer types, including `uint8_t`. Make sure that you have the necessary libraries and header files included in your project settings.

Here's an example of how to include `<stdint.h>` in your code:

#include <stdint.h>

int main(void) {
    uint8_t myVariable;
    
    // Rest of your code
    
    return 0;
}

By including `<stdint.h>`, the compiler will recognize the `uint8_t` type and you won't encounter the "unknown type name" error.

回答: 在移植LVGL时，您遇到了一个问题，即在Keil编译时提示“uint8_t is not a type name”和“inline is undefined”。这个问题的原因是您在设置中没有勾选C99 Mode，导致出现了两千多个错误。解决这个问题的一个方法是在项目的Building setting中，将Searchpaths下的HeaderSearchpaths中的/usr/local/lib改为非递归(non-recursive)。\[1\]\[2\]这样做可以解决该问题。
