问题 On my server (Debian) I had some problem with the execution of php files, I thought I would check if the latest version was installed so I wrote: apt-get install php5-cli It turned out that php5 wasn't even installed yet.

问题 Currently working on the GPIOs of a SBC (Olimex A20), I have a problem with QSocketNotifier. On my GPIOs, I'm using a pin with interruption abilities (For those who want to know more : https://developer.ridgerun.com/wiki/index.php/How_to_use_GPIO_signals ) and a QSocketNotifier to monitor the changes.

问题 I have a source tree structure like - /src /moduleA /moduleB /common where moduleA and moduleB need packaged separately but share the common code. Is it possible to create 2 separate binary packages using dpkg-buildpackage? Thanks! 回答1: It is possible. In order to do it, you should modify the control file.
