mysql - 找不到符号 mysql_select_db@libmysqlclient_16 的版本节点

Question

我试图使用 mysql c api 在 linux 上构建我的应用程序，并在链接阶段遇到此错误，它在 windows 上工作正常。请帮忙，谢谢!

错误信息:

/bin/ld: myapp.so : version node not found for symbol mysql_select_db@libmysqlclient_16
/bin/ld: failed to set dynamic section sizes: Bad value

操作系统:CentOS 7，64 位，(虚拟机上的虚拟机)

Mysql:5.6.24(社区版，通过yum安装)

.bashrc 文件

export LIBMYSQL_INCLUDE_DIR=/usr/include/mysql
export LIBMYSQL_LIBRARY=/usr/lib64/mysql
export LD_LIBRARY_PATH=/usr/lib64/mysql:$LD_LIBRARY_PATH

cmake文件:(变量根据环境变量设置)

FILE(GLOB SRC_MYAPP myapp/*.c myapp/*.h)
INCLUDE_DIRECTORIES(${LIBMYSQL_INCLUDE_DIR})

ADD_LIBRARY(myapp ${SRC_MYAPP})
IF (MSVC_IDE)
  TARGET_LINK_LIBRARIES(myapp ${LIBMYSQL_LIBRARY}/libmysql)
ELSE ()
  TARGET_LINK_LIBRARIES(myapp ${LIBMYSQL_LIBRARY}/libmysqlclient_r.a)
ENDIF ()

将@hank 的评论作为答案

我想你应该在 add_library 之前添加 link_directories(/usr/lib64/mysql) 然后是 target_link_libraries(myapp mysqlclient_r) – hank May 12 点 12:50
