问题描述
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
I'm trying to use the mySQL c++ connector.I have downloaded and extracted the binaries following the mysql guide https://dev.mysql.com/doc/connector-cpp/8.0/en/connector-cpp-installation-binary.html
当我像这样包含xdevapi时
When i include the xdevapi like so
#include <mysqlx/xdevapi.h>
我遇到以下错误

collect2:错误:ld返回1个退出状态

Makefile:2:目标"x86"的配方失败
Makefile:2: recipe for target 'x86' failed
make:*** [x86]错误1
make: *** [x86] Error 1
我的Makefile如下:
My Makefile look like this:
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?
Does anyone know what I'm missing here?
推荐答案
您未与MySQL库链接:
You are not linking with the MySQL library:
-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
