问题

在以下代码片段（用于 ARM 嵌入式芯片的 C 代码）中，

```c
typedef struct __attribute__((__packed__)) MyStruct_S
{
    int MyFirstField;
    int MySecondField;
} MyStruct_Type;

VS Code 对 MyStruct_S 标识符之后的属性发出投诉。投诉内容为"expected a ';'C/C++(65)"。

然而，即使设置了 -Wall 和 -Wextra 编译器标志，这段代码仍然可以编译并正常运行。

VS Code 做错了什么？ 我们可以修复 IntelliSence 以识别这是正确的语法吗？

我在此工作区中安装的扩展如下：

• Arm Assembly
• C/C++
• Doxygen Documentation Generator
• GNU Linker Map files
• Makefile Tools
• WSL

祝好！

In the following code snippet (C, for ARM embedded chips)

typedef struct attribute((packed)) MyStruct_S
{
int MyFirstField;
int MySecondField;
} MyStruct_Type;

VS Code complains on the MyStruct_S identifier, following the attribute. The complaint says "expected a ';'C/C++(65)".

And yet this code compiles and runs just fine even with -Wall and -Wextra compiler flags set. 

**What is VS Code doing wrong?** Can we fix the IntelliSence to see that this is correct syntax?


The extensions I have for this workspace are the following:

 - Arm Assembly
 - C/C++
 - Doxygen Documentation Generator
 - GNU Linker Map files
 - Makefile Tools
 - WSL

cheers!

你应该更改C/C++扩展配置。在`Intellisense Mode`下选择一个合适的配置。在Windows上，默认设置为`windows-msvc-x64`，而在Linux上为`linux-gcc-x64`。创建一个新的C/C++配置（使用`C/C++: Edit Configurations`命令），并将Intellisense Mode设置为`linux-gcc-arm`。然后针对你的项目，使用`"C/C++: Select a configuration..."`命令更改你的配置。

You should change the C/C++ Extension Configurations. Select a suitable one under the `Intellisense Mode`. On Windows, it is by default set to windows-msvc-x64, and on Linux, linux-gcc-x64. Create a new C/C++ configuration (`C/C++: Edit Configurations` command), and set the Intellisense Mode to `linux-gcc-arm`. Then for your project, using the `&quot;C/C++: Select a configuration...&quot;` command change your configuration.
