本文介绍了在配置PHP过程中遇到的MySQL支持问题及其解决方案。主要原因是编译Apache时使用了--with-mpm模块，需要在编译MySQL时添加--enable-thread-safe-client参数。此外还提供了一种简便的方法通过创建符号链接解决libmysqlclient_r.so库文件的问题。

配置php的时候出现以下问题解决方案

checking for MySQL support... yes
checking for specified location of the MySQL UNIX socket...no
checking for MySQL UNIX socket location... no
configure: error: Cannot find libmysqlclient_r under/usr/local/mysql. Note that the MySQL client library is not bundledanymore!

其实这跟PHP没有关系，那是因为在编译APACHE的时候，使用--with-mpm模块，所以就必须在编译MYSQL的时候加上--enable-thread-safe-client.参数
这是PHP5.2的一个改进，在PHP5.2.0之前的版本都不需要MYSQL启用安全线程。关于--enable-thread-safe-client项的官方介绍如下:如何生成线程式客户端库总是线程安全的。最大的问题在于从套接字读取的net.c中的子程序并不是中断安全的。或许你可能希望用自己的告警中断对服务器的长时间读取，以此来解决问题。如果为SIGPIPE中断安装了中断处理程序，套接字处理功能应是线程安全的。SupeSite/X-为了避免连接中断时放弃程序，MySQL将在首次调用mysql_server_init()、mysql_init()或mysql_connect()时屏蔽SIGPIPE。如果你打算使用自己的SIGPIPE处理程序，首先应调用mysql_server_init()，然后安装你的处理程序.


还有第二种解决方法比较方便：编译之前，先处理一下mysql的库，默认查找libmysqlclient_r.so，可是mysql默认为libmysqlclient.so，内容完全一样，做个链接即可
# cd /usr/local/mysql/lib/mysql/ 
# ln -s libmysqlclient.so.15.0.0 libmysqlclient_r.so

<think>好的，我现在要解决用户在编译过程中遇到的链接错误问题，具体是关于libcgroup.so.2未找到以及libcmcommon.so中的多个未定义引用，比如etcd_open、cgroup_attach_task_pid等函数。用户还提到需要调整CMakeLists.txt配置。我需要一步步分析可能的原因，并提供解决方案。 首先，用户提到的错误分为两部分：一个是libcgroup.so.2未找到，另一个是多个未定义的函数引用。这两个问题通常都与链接器的配置有关，可能涉及到库的安装路径、链接选项的设置，或者依赖库的缺失。 针对libcgroup.so.2未找到的问题，可能的原因是这个库没有安装在系统的标准库目录中，或者编译时没有正确指定库的路径。解决方案可能包括安装对应的开发包，比如libcgroup-dev，或者在CMakeLists.txt中通过link_directories命令添加库的路径。另外，检查库文件是否存在，比如使用find命令搜索libcgroup.so.2的位置，然后确保CMake能正确找到。 接下来是未定义的引用错误，比如etcd_open、cgroup_attach_task_pid这些函数。这些错误通常是因为链接器找不到实现这些函数的库。需要确认这些函数属于哪个库，并确保该库被正确链接。例如，cgroup_attach_task_pid可能在libcgroup中，而etcd_open可能在libetcd或其他相关库中。用户需要检查是否安装了这些库的开发版本，并在CMake中使用target_link_libraries将对应的库添加到项目中。 另外，用户提到了CMakeLists.txt的调整，可能需要检查是否有正确的find_package命令或者pkg_check_modules来查找这些依赖库。如果CMake无法自动找到这些库，可能需要手动设置库的路径和名称。 可能的解决步骤包括： 1. 安装缺少的依赖库，如libcgroup-dev、libetcd-dev等。 2. 在CMakeLists.txt中添加库的搜索路径，使用link_directories。 3. 确保target_link_libraries中包含了所有必需的库，比如cgroup、etcd等。 4. 检查库文件的实际名称和路径是否正确，可能需要使用绝对路径。 5. 使用ldd或nm工具验证库中是否包含所需的符号。 还需要考虑动态库的运行时路径问题，是否需要在编译时指定rpath，或者设置LD_LIBRARY_PATH环境变量。此外，检查CMake的版本和配置是否合适，有时候不同的CMake版本处理依赖的方式不同。 用户可能需要具体指导如何修改CMakeLists.txt，例如添加include_directories和link_directories，以及正确设置target_link_libraries的顺序，因为链接顺序也可能影响解决依赖关系。例如，依赖其他库的库应该放在前面，被依赖的库放在后面。 此外，如果某些库是第三方或自行编译的，可能需要手动指定它们的路径，或者使用find_library命令在CMake中显式查找。如果存在多个版本的库，还需要确认链接的是正确的版本。 总结来说，解决步骤可能包括安装依赖、调整CMake配置确保正确的链接路径和库名称，以及验证符号的存在。需要分步骤指导用户进行操作，并建议他们检查每一步的结果，比如安装包后确认文件存在，修改CMake后重新生成构建系统并重新编译，观察错误是否解决。</think>### 分步解决方案 #### 一、解决libcgroup.so.2未找到问题 1. **安装缺失的开发包** 通过包管理器安装`libcgroup`开发包： ```bash sudo apt-get install libcgroup-dev # Debian/Ubuntu # 或 sudo yum install libcgroup-devel # CentOS/RHEL ``` 2. **验证库文件路径** 确认库文件存在并记录路径： ```bash find /usr -name "libcgroup.so*" 2>/dev/null # 典型路径：/usr/lib/x86_64-linux-gnu/libcgroup.so.2 ``` 3. **修改CMakeLists.txt** 在`CMakeLists.txt`中添加库搜索路径（根据实际路径调整）： ```cmake link_directories(/usr/lib/x86_64-linux-gnu) # 添加库所在目录 ``` --- #### 二、解决未定义引用错误（如etcd_open、cgroup_attach_task_pid） 1. **确认依赖库归属** - `cgroup_attach_task_pid`属于`libcgroup` - `etcd_open`可能属于`libetcd`或其他第三方库，需安装对应开发包： ```bash sudo apt-get install libetcd-dev # 示例，具体包名需根据实际情况调整 ``` 2. **链接缺失的库** 在`CMakeLists.txt`的`target_link_libraries`中添加所有依赖库： ```cmake target_link_libraries(your_target_name PRIVATE cgroup # 链接libcgroup.so etcd # 链接libetcd.so cmcommon # 链接libcmcommon.so ) ``` 3. **处理库依赖顺序** **确保基础库在前，依赖库在后**。例如若`libcmcommon`依赖`libcgroup`，则： ```cmake target_link_libraries(your_target_name PRIVATE cmcommon cgroup etcd ) ``` --- #### 三、高级调试技巧 1. **验证符号是否存在** 使用`nm`检查库文件是否包含缺失符号： ```bash nm -D /path/to/libcgroup.so | grep cgroup_attach_task_pid nm -D /path/to/libetcd.so | grep etcd_open ``` 2. **强制指定库路径** 若库不在默认路径，直接指定绝对路径： ```cmake target_link_libraries(your_target_name PRIVATE /custom/path/libcgroup.so ) ``` 3. **设置运行时库路径** 在CMake中通过`RPATH`指定运行时库搜索路径： ```cmake set(CMAKE_INSTALL_RPATH "$ORIGIN:/custom/path") ``` --- #### 四、完整CMake配置示例 ```cmake cmake_minimum_required(VERSION 3.10) project(your_project) # 添加头文件搜索路径 include_directories(/usr/include/cgroup) # 添加库搜索路径 link_directories(/usr/lib/x86_64-linux-gnu /custom/libs) # 生成可执行文件 add_executable(main main.cpp) # 链接依赖库 target_link_libraries(main PRIVATE cmcommon cgroup etcd ) ``` ---
