CMake无法找到mysqlclient库 [英] CMake unable to find mysqlclient library

问题描述

我正在使用 CMake 生成一个makefile，以编译使用boost，eigen和mysqlclient库的C ++项目.

I'm using CMake to generate a makefile to compile a C++ project that uses the boost, eigen, and mysqlclient libraries.

在生成过程中，代码似乎可以编译，但是在链接阶段我得到了错误

During the make process the code seems to compile, but then at the linking stage I get the error

ld: library not found for -lmysqlclient

我有一行 target_link_libraries(my_executable mysqlclient)在我的 CMakeLists.txt 文件中.当我删除该行时，我不再得到该错误消息，但是却得到了一长串未定义的符号错误(都与mysql有关).该项目可以在Xcode中正确构建，因此我知道至少在我的计算机上设置了mysql客户端库.有提示，建议吗?

I have the line target_link_libraries(my_executable mysqlclient) in my CMakeLists.txt file. When I remove that line, then I no longer get that error message, but then I get a long list of undefined symbols errors (all having to do with mysql). The project builds correctly in Xcode, so I know that at least the mysql client libraries are set up on my machine. Any tips, suggestions?

推荐答案

您将要使用Kitware中的 FindMySQL.make 包(将文件保存在此处:

You will want to use the FindMySQL.make package from Kitware (save the file here: https://cmake.org/Wiki/CMakeUserFindMySQL as ${CMAKE_SOURCE_DIR}/cmake/FindMySQL.cmake), then find the library:

set(CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH} "${CMAKE_SOURCE_DIR}/cmake/")    
find_package(MySQL)

最后，您在cmake中的链接步骤应替换为

Finally, your link step in cmake should be replaced with

target_link_library(myexecutable ${MYSQL_LIBRARY})

$ {MYSQL_LIBRARY} 应该包含要链接的库文件的标准路径.

${MYSQL_LIBRARY} should contain the fully qualified path to the library file that you want to link with
