第一步:准备工作
gcc,装完之后,,还要装一些类库,要不会出很多错误

sudo apt-get install g++,glibc,glibc-source,build-essential,libmysql++dev,libmysqlclient15off,libmysqlclient15-dev

上面这些东西,我也不知道哪些真正有用,反正这些我都给装上了

第二步:
示例程序(别人的)

#include
#include
#include
#include

int main(){
MYSQL *mysql;
MYSQL_RES *res;
MYSQL_ROW row;
char query[1024];
int t,r;

mysql=mysql_init(NULL);
if (!mysql_real_connect(mysql,"test","root",
"123","test",0,NULL,0))
{
printf( "Error connecting to database: %s\n",mysql_error(mysql));
}
else printf("Connected...\n");

sprintf(query,"select * from first");

t=mysql_query(mysql,query);

if (t)
{
printf("Error making query: %s\n",
mysql_error(mysql));
}
else printf("Query made...\n");
res=mysql_use_result(mysql);
for(r=0;rrow=mysql_fetch_row(res);
if(rowfor(t=0;tprintf("%s",row[t]);
printf("\n");
}
mysql_close(mysql);
return 0;
}


然后gcc test.c -lmysqlclient

另外#include 这里也可能会出现问题,如果需要可以自己修改成绝对路径,再试一下子。
