我有一个用 C++ 编写的嵌入式应用程序（在 Linux 环境中的 PowerPC 上运行），它访问外部数据库。所以我的应用程序需要 mysql++ 库，这些库需要使用 powerpc 编译器构建。在构建库之前，我想在我的 Ubuntu VM 上为 linux 构建 mysql++ 库以检查过程。我从官网下载了最新的包。然后我按照提到的步骤进行操作。
- 从根目录运行 ./configure，我收到以下错误。
*检查 MySQL 库目录...配置：错误：在 '/usr/lib64 /usr/lib /usr/lib64/mysql /usr/lib/mysql /usr/local/lib64 /usr/ 中找不到 mysqlclient 库local/lib /usr/local/lib/mysql /usr/local/mysql/lib /usr/local/mysql/lib/mysql /usr/mysql/lib/mysql /opt/mysql/lib /opt/mysql/lib/ mysql /sw/lib /sw/lib/mysql' *
我尝试查找 mysqlclient 并没有找到任何参考，因此我按照其他论坛中给出的说明并尝试使用以下命令安装 libmysqlclient15-dev。
sudo apt-get install libmysqlclient15-dev
输出如下图
读取包列表...完成构建依赖树
读取状态信息...完成注意，选择'libmysqlclient-dev'而不是'libmysqlclient15-dev' libmysqlclient-dev 已经是最新版本。

After this I tried to locate libmysqlclient and I still couldn't find the libraries (.so files). I tried ./configure again and it failed in the same location with the same error message. How can I install libmysqlclient ?
Once this is solved I will rebuild the mysql++ library using my toolchain for powerpc. Has anyone tried this ? To build mysql++ library I need mysqlclient, in the earlier example I would install it by executing the command apt-get, but the libraries would be compiled using a gnu compiler ? How to cross compile mysqlclient for powerpc ? I guess I need to do the below
- Build mysqlclient for powerpc.
- Use those libraries and build mysql++ libraries for powerpc.
- Use mysql++ and mysqlclient libraries in my application and compile for powerpc.
I am new to linux and databases.
