无法在Ubuntu 16.04 LTS – 64bit中编译Qt 5.6.0 mysql插件
我最近将Qt升级到5.6.0版，将我的Ubuntu工作站升级到版本16.04 LTS 。 现在，我知道我必须重新编译mysql plugin并且我已成功完成了几次。 但是，在将Ubuntu 14.04 LTS升级到Ubuntu 16.04 LTS同时升级 mysql server时遇到了问题我已经通过备份数据库并从Ubuntu 16.04 LTS存储库中清除并重新安装mysql server 5.7来解决它， mysql server现在工作正常。 然后我尝试重新编译qt mysql plugin ：
user@work002:/opt/Qt/opensource/64bit/5.5/5.6/Src/qtbase/src/plugins/sqldrivers/mysql$ clear && make clean && /opt/Qt/opensource/64bit/5.5/5.6/gcc_64/bin/qmake "INCLUDEPATH+=/usr/local/include" "LIBS+=-Lusr/local/lib -lmysqlclient_r" mysql.pro && make all && make install
从如何在Unix和OS X官方文档上构建QMYSQL插件 ，我得到以下链接器错误 ：

根据用户adonis评论 ，我已将compilation command更改为

这肯定是一些愚蠢的错误，但我根本找不到它，为什么我会得到这个错误，我可能错过了一些包吗？
libmysqlclient_r.so不是ubuntu 16.04中libmysqlclient一部分。 在使用以下命令运行命令之前，可以为兼容的libmysqlclient.so创建符号链接：
sudo ln -s /usr/lib/x86_64-linux-gnu/libmysqlclient.so /usr/lib/x86_64-linux-gnu/libmysqlclient_r.so
在Kubuntu 16.04
cp /opt/Qt/5.5/gcc/plugins/sqldrivers/libqsqlmysql.so /opt/Qt/5.5/gcc/plugins/sqldrivers/libqsqlmysql.so.ori cp /usr/lib/i386-linux-gnu/qt5/plugins/sqldrivers/libqsqlmysql.so /opt/Qt/5.5/gcc/plugins/sqldrivers/libqsqlmysql.so
