Question

我想在我的raspberry Pi上设置connector / c ++来访问mysql数据库。起初我试过了：

sudo apt-get install libmysqlcppconn-dev

已成功安装，但我收到错误：

ERR: MySQL_Connection::setReadOnly() (MySQL error code: 0, SQLState:  )

附带cppconn我正在使用的版本，正如其中所述：MySQL Connector for C++ | MySQL_Connection::setReadOnly() exception on setSchema

当我检查时：

sudo apt-cache show libmysqlcppconn-dev

它说＆＃34;版本：1.1.0-4＆＃34;

然后我尝试从源代码安装最新的软件包： { - 3}}下的＆gt;源代码 - ＆gt;通用Linux（独立于架构），压缩TAR存档

我下载了它并且做了＆＃34; tar xvzf mysql -....＆＃34;一切正常。但是当我尝试使用

构建它时

cmake .

我收到了错误：

我知道这意味着，它无法找到mysql_config，但我也不知道如何告诉它文件的位置，也不知道文件的实际位置。

所以请帮助我。我很讨厌这个。

非常感谢。

编辑：

我尝试手动安装最新的软件包，我从以下网址下载：

https://dev.mysql.com/downloads/connector/cpp/

sudo dpkg -i libmysqlcppconn7_1.1.3-6_armhf.deb
sudo dpkg -i libmysqlcppconn-dev_1.1.3-6_armhf.deb

现在我明白了：

这是好还是坏？

Answer 1

您需要安装MySQL客户端库开发文件：

apt-get install libmysqlclient-dev

尝试确保安装所有依赖项的更简单方法是要求apt为其打包版本安装所有构建依赖项：

apt-get build-dep libmysqlcppconn-dev

Answer 2

libmysqlclient-dev软件包已不存在。我猜它已重命名。因此，要安装c ++连接器，请使用以下新软件包：

sudo apt install libmysql++-dev

在raspberryPi上安装mysql连接器c ++
