Eu atualizei recentemente o Qt para a versão 5.6.0 e minha Ubuntu estação de trabalho para a versão 16.04 LTS . Agora, eu sei que tenho que recompilar mysql plugin e consegui fazer isso várias vezes. No entanto, eu tinha atualização de problemas mysql server ao atualizar Ubuntu 14.04 LTS para Ubuntu 16.04 LTS e resolvi com fazer backup de bancos de dados e remover e reinstalar mysql server 5.7 de Ubuntu 16.04 LTS repositories, mysql server now funciona bem. Então eu tentei recompilar qt mysql plugin com:
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
de Como construir o plugin QMYSQL na documentação oficial do Unix e OS X e Eu recebo seguindo linker error :
