qt creator编译问题之 can not find -lQtGui

Posted 2021-03-17 7star

今天尝试在（qtcreator 4.7.0 + Qt 4.8.6）下编译，遇到找不到库文件问题，先开始想到的是环境配置问题

检查下来也没有线索， 又想是不是没有链接路径，参考网上，试了两个个命令

ld -lQtNetwork --verbose 

locate libQtNetwork

ld -lQtNetwork --verbose 

locate libQtNetwork

发现x86_64没有定位到libQtNetwork.so.4.8.6的软连接，于是

sudo ln -s /usr/lib/x86_64-linux-gnu/libQtNetwork.so.4.8.6 /usr/lib/x86_64-linux-gnu/libQtNetwork.so
sudo ln -s /usr/lib/x86_64-linux-gnu/libQtGui.so.4.8.6 /usr/lib/x86_64-linux-gnu/libQtGui.so
sudo ln -s /usr/lib/x86_64-linux-gnu/libQtCore.so.4.8.6 /usr/lib/x86_64-linux-gnu/libQtCore.so

QT可以编译，
