mysql 在 raspberryPi 上安装连接器 c++

Question

我想在我的 raspberry Pi 上设置 connector/c++ 以访问 mysql 数据库。一开始我试过：

sudo apt-get install libmysqlcppconn-dev

安装成功，但出现错误：

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

这是我正在使用的 cppconn 版本附带的，如此处所述：MySQL Connector for C++ | MySQL_Connection::setReadOnly() exception on setSchema

当我检查时：

sudo apt-cache show libmysqlcppconn-dev

它说 "version: 1.1.0-4"

然后我尝试从源安装最新的包： https://dev.mysql.com/downloads/connector/cpp/ 位于 ->Source Code -> Generic Linux (Architecture Independent), Compressed TAR Archive

我下载并执行了 "tar xvzf mysql-...."，一切正常。但是当我尝试用

构建它时

cmake .

我收到错误：

我知道这意味着，它找不到 mysql_config，但我也不知道如何告诉它文件在哪里，也不知道文件实际在哪里。

所以请帮助我。我受够了。

非常感谢。

编辑：

我尝试手动安装最新的软件包，我从以下位置下载：

https://packages.debian.org/jessie/armhf/libmysqlcppconn-dev/download

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

现在我得到：

这是好事还是坏事？

Answer 1

您需要安装 MySQL 客户端库开发文件：

apt-get install libmysqlclient-dev

尝试并确保安装所有依赖项的更简单方法是要求 apt 为它的打包版本安装所有构建依赖项：

apt-get build-dep libmysqlcppconn-dev

Answer 2

libmysqlclient-dev 软件包不再存在。估计改名了所以要安装 c++ 连接器，有这个新包：

sudo apt install libmysql++-dev

mysql 在 raspberryPi 上安装连接器 c++

mysql connector c++ install on raspberryPi

c++
