MySQL库没有链接

我使用cmake来构建我的项目文件。

这是我的附加链接库：

kernel32.lib
user32.lib
gdi32.lib
winspool.lib
shell32.lib
ole32.lib
oleaut32.lib
uuid.lib
comdlg32.lib
advapi32.lib
..\boost\Debug\boost_lib_thread.lib
..\boost\Debug\boost_lib_system.lib
..\global\Debug\global.lib
C:\Program Files (x86)\OpenSSL-Win32\lib\VC\libeay32MD.lib
C:\Program Files (x86)\OpenSSL-Win32\lib\VC\ssleay32MDd.lib
C:\Program Files (x86)\OpenSSL-Win32\lib\VC\libeay32MDd.lib
C:\Program Files\MySQL\MySQL Server 5.5\lib\libmysql.lib

我在尝试编译时遇到以下错误：

答案 0 :(得分：0)

除了libmysql之外，尝试添加libmysqlpp。这是C ++ API，它来自您尝试使用的链接器错误。
