我正在尝试使用mysql c++连接器。我已经按照mysql指南下载并提取了二进制文件https://dev.mysql.com/doc/connector-cpp/8.0/en/connector-cpp-installation-binary.html
当我像这样包含xdevapi时


# include <mysqlx/xdevapi.h>

我得到以下错误
/tmp/cc6dzd4k.o:在函数中mysqlx::string::operator std::u cxx11::basic_string,std::allocator>abi:cxx11 const': /git\u repos/fhm/camera/software/extractmatadata/build/linux/../../../mysql-connector-c++-8.0.13/include/mysqlx/devapi/common.h:115:未定义对mysqlx::string::impl::to\u utf8的引用[abi:cxx11](mysqlx::string const&)'

makefile:2:目标“x86”的配方失败
make:**[x86]错误1
我的makefile如下所示:

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 \

有人知道我错过了什么吗?

您没有链接到mysql库:

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

用途:

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

或:

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