error while loading shared libraries, file too short

- by tommyk

From one of my customers I got an application. When I try to run it I got following error error while loading shared libraries: ./libvtkWidgets.so.5.4: file too short In my project structure I see following: -rwxrwxrwx 1 tomasz tomasz 20 2011-02-01 10:44 libvtkWidgets.so -rwxrwxrwx 1 tomasz tomasz 22 2011-02-01 10:44 libvtkWidgets.so.5.4 -rwxrwxrwx 1 tomasz tomasz 2147103 2011-02-01 10:44 libvtkWidgets.so.5.4.2 Is my shared library libvtkWidgets corrupted ?

apt-get does not work with proxy

- by tommyk

For a command sudo apt-get update I get following error W: Failed to fetch http://ch.archive.ubuntu.com/ubuntu/dists/maverick-updates/multiverse/binary-i386/Packages.gz 407 Proxy Authentication Required ( The ISA Server requires authorization to fulfill the request. Access to the Web Proxy filter is denied. ) I am running Ubuntu 10.10 installed on Windows XP using VirtualBox. For internet connections I am using proxy server with an authentication. I tried to use gnome-network-proxy tool to set proxy settings system-wide. After that /etc/environment has been updated by http_proxy variable with the format http://my_proxy:port/, there were no authentication data. I checked this with firefox. Browser asked my for login and password and everything was working fine. It was unfortunately not the case for apt-get. I have also tried to do as described here. Unfortunately it does not work. May it be somehow related to the fact that a proxy is in a Windows domain, any ideas ? EDIT: My proxy name is http-proxy. Is '-' a special character here ?

Smart pointer class predeclaration

- by tommyk

I have a header file: class A { public: DeviceProxyPtr GetDeviceProxy(); }; DeviceProxyPtr is defined in a different header file like this: typedef SmartPtrC<DeviceProxyC> DeviceProxyPtr; I don't want to include DeviceProxyPtr definition header. If a return type was DeviceProxy* I could simply use predeclaration class DeviceProxy. Is there any way to do the same with my smart pointer class?
