置顶贴子，此版块的贴子都看了尝试了还不行，
环境：redhat9，qt-x11-opensource-src-4.5.3，mysql-5.1.51，都已经安装成功了，
我的环境下没有如下的include 和lib的目录，
"INCLUDEPATH+=/usr/include/mysql" "LIBS+=-L/usr/lib/mysql -lmysqlclient_r" mysql.pro
而是
"INCLUDEPATH+=/usr/local/mysql/include/mysql" "LIBS+=-L/usr/local/mysql/lib/mysql -lmysqlclient_r" mysql.pro
这样的目录
报错如下：
[root@localhost mysql]# qmake "INCLUDEPATH+=/usr/local/mysql/include/mysql" "LIBS+=-L/usr/local/mysql/lib/mysql -lmysqlclient_r" mysql.pro
[root@localhost mysql]# ls
