ubuntu安装unixodbc-gui-qt的时候出错，提示configure: error: cannot compile a Qt program!

Posted 2023-04-06

：./configure --with-qt-dir-include=/usr/include/qt4 --with-qt-dir-lib=/usr/lib/qt4 --with-qt-dir-bin=/usr/share/qt4/bin
以下是运行./configure之后所有的提示（由于长度限制的问题，省略了前面正确提示的部分）：

重点就是最后几句：
configure: checking for Qt
yes (/usr/include/qt4)
yes (/usr/lib/qt4)
yes (/usr/share/qt4/bin)
checking for /usr/include/qt4/QtGui/QWizard... yes
checking for /usr/include/qt4/QtGui/QMdiArea... yes
configure: qt_dir_lib=/usr/lib/qt4
configure: LDFLAGS=
configure: X_LIBS=
checking whether a simple Qt program compiles... no
configure: error: cannot compile a Qt program!
高分求解，拜托了

参考技术A 最后几句的解释也就是在检查是否能够编译QT程序的时候出的错，配置问题也就是不能编译QT程序，问题可能是出在安装过程了吧，要不你重新安装下试试，或者下载的安装包有问题。 参考技术B --with-qt-dir=/usr/lib/qt4 看能不能通过configure
不行的话，把你的 /etc/ld.so.conf 和 /etc/ld.so.conf.d/qt-i386.con本回答被提问者采纳 参考技术C sudo 试试

ubuntu下播放h264,h265文件

vlc可以播放h264,h265文件, 并且既可以在win下,可以在ubuntu下

1. 安装vlc
   在ubuntu软件中心,搜索vlc,既可以看到vlc media player,点击安装
2. 对于h264结尾的文件,可以直接使用命令播放
   vlc *.h264
3. 对于h265文件, 我安装的时v2.1.6版本,不支持h265, 需要安装一库,采用ppa的方式
   sudo add-apt-repository ppa:strukturag/libde265
   sudo aptitude update
   sudo apt-get install vlc-plugin-libde265
   
   1. 然后就可以用vlc命令播放h265文件了
      vlc *.h265
