Question

我正在尝试使用mySQL c ++连接器。我已经按照mysql指南https://dev.mysql.com/doc/connector-cpp/8.0/en/connector-cpp-installation-binary.html

下载并提取了二进制文件

当我像这样包含xdevapi时

#include <mysqlx/xdevapi.h>

我遇到以下错误

/tmp/cc6dzD4k.o：在函数mysqlx :: string :: operator std :: __ cxx11 :: basic_string，std :: allocator> abi：cxx11 const'：

中

collect2：错误：ld返回1个退出状态

Makefile：2：目标“ x86”的配方失败

make：*** [x86]错误1

我的Makefile如下：

g++ -I../../Src -I../../../Fee/Src \
-I/../../../OpenCV/include/opencv \
-I../../../OpenCV/include/opencv2 \
-I../../../mysql-connector-c++-8.0.13/include/ \
-L../../../OpenCV/lib/LinX86 \
-L../../../mysql-connector-c++-8.0.13/lib64/libmysqlcppconn8-static.a -lssl -lcrypto -lpthread \
-g -D LINUX -o extractmetadata ../../Src/extractMetadata.cpp ../../../Fee/Src/Status.cpp \
-std=c++11 \
-lopencv_world -lstdc++fs \

有人知道我在这里想念什么吗？

您未链接到MySQL库：

-L../../../mysql-connector-c++-8.0.13/lib64/libmysqlcppconn8-static.a

使用：

../../../mysql-connector-c++-8.0.13/lib64/libmysqlcppconn8-static.a

或：

-L../../../mysql-connector-c++-8.0.13/lib64/ -lmysqlcppconn8-static

使用mysql c ++连接器的未定义参考
