Question

我尝试将DEV c ++与mysql连接，但它不断显示错误“在C：/ Program Files / MySQL / MySQL Server 8.0 / include / mysql.h中包含的文件中

C：\ Program Files \ MySQL \ MySQL Server 8.0 \ include \ mysql_com.h [错误] mysql / udf_registration_types.h：没有这样的文件或目录“

#include <iostream>
#include <windows.h>
#include <C:/Program Files/MySQL/MySQL Server 8.0/include/mysql.h>

using namespace std;

int main(){

    system("PAUSE");

    return 0; 

}

我对Dev-C ++不熟悉。

在项目属性中，找到选项“包含目录”（在“编译”部分的某个位置，然后添加以下条目：

return GridView.builder(
gridDelegate: SliverGridDelegateWithFixedCrossAxisCount(
crossAxisCount: 1,mainAxisSpacing: 0.0,crossAxisSpacing: 0),
shrinkWrap: false,
itemCount: map.values.toList().length,
padding: EdgeInsets.all(2.0),
itemBuilder: (BuildContext context, int index) {
  return new Column(
      mainAxisSize: MainAxisSize.min,
      children: <Widget>[
      Flexible( child: Card(
    child: new InkWell(
      onTap: () {
        Navigator.push(
          context,
          MaterialPageRoute(builder: (context) => ContactUsPage(map.values.toList()[index]["articleUrl"])),
        );
      },
      child: new Padding(
        padding: const EdgeInsets.all(4.0),
        child:new Column(
          mainAxisSize: MainAxisSize.min,
          mainAxisAlignment: MainAxisAlignment.start,
          crossAxisAlignment: CrossAxisAlignment.start,
          children: <Widget>[
        Flexible(
        child:
            Container(
              alignment: Alignment.topCenter,
              width: double.infinity,
              height: 500,

            SizedBox(

            SizedBox(

                    IconButton(icon: Icon(Icons.thumb_up,), onPressed: (){

                    IconButton(icon: Icon(Icons.comment,), onPressed: (){

                    IconButton(icon: Icon(Icons.share,), onPressed: (){

                  ],
                ),
              fit: FlexFit.loose,
              flex: 2,

      ),
    ),
  ),
    fit: FlexFit.loose,
      ),

  );
},

} else {
return Center(
child: CircularProgressIndicator()

}

}));

在互联网上找到的图片（可能需要使用C:\Program Files\MySQL\MySQL Server 8.0\include标签）：

将您的include语句更改为：

C++ Includes

别忘了添加链接程序的路径和库以链接sql库。
