编译QT时遇到的问题自我解决 [复制链接]

最近安装qt-x11-2.3.2,文件存储路径为/usr/qtopia/qt-2.3.2,我用的操作系统是Ubuntu8.04,设置好环境变量，诸如QTDIR，可是在执行命令：./configure -no-opengl时总是出现如下错误：
strive@strive-laptop:/usr/qtopia/qt-2.3.2$ ./configure -no-opengl
touch: cannot touch `.test.qt.': Permission denied
rm: cannot remove `.test.qt.': No such file or directory


   The environment variable $QTDIR is not set correctly. It is currently
   set to "/usr/qtopia/qt-2.3.2", but it should be set to this directory,
   which is "/usr/qtopia/qt-2.3.2".

   Please read the INSTALL file for instructions on how to set $QTDIR
   correctly. If you have set $QTDIR in your .profile or .login, you
   will need to log out and log in again to make the setting effective.
通过错误提示认为是因为自己权限不够，于是执行如下命令：
strive@strive-laptop:/usr/qtopia/qt-2.3.2$ sudo ./configure -no-opengl
[sudo] password for strive:


   The environment variable $QTDIR is not set correctly. It is currently
   set to "", but it should be set to this directory,
   which is "/usr/qtopia/qt-2.3.2".

   Please read the INSTALL file for instructions on how to set $QTDIR
   correctly. If you have set $QTDIR in your .profile or .login, you
   will need to log out and log in again to make the setting effective.
显然依然不可以，网上搜索未果。
后来发现可以如此解决:
首先，启用ROOT用户：$sudo passwd root
这样设置ROOT密码，然后执行如下命令：su
切换到ROOT用户,然后再以root身份设置QTDIR环境变量即可！

昨天我发帖居然没有人理我，自己顶！！

编译安装QT/e，出现上述kernel/qwsutils_qws.h:37:41: error: qwssocet_qws.h: No such file or directory错误怎么办？求大家了

不用root用户身份，而只是你登陆时的身份，应该也是可以设置环境变量的。
