cross-platform

I have a C program that I'm developing using Ubuntu 11.10 (Linux version 3.0.0-12-generic-pae kernel). I need to run that program in a cluster that has Debian 3.1 (Linux version 2.4.24-om2) installed, and uses Intel(R) Pentium(R) 4 CPU 3.20GHz processors. The problem is that I can't compile in the Debian cluster because it doesn't have installed the GSL library that my program needs, and I don't know how to install it (or make use of it) without root privileges. If I try to run the executable I compiled in Ubuntu (or a simple hello world program, for the case), it doesn't work, even if I

I'm learning wxPython so most of the libraries and classes are new to me. I'm creating a Preferences dialog class but don't know the best way to make sure the OK/Cancel (or Save/Close) buttons are in the correct order for the platform. This program is intended to run both on GNOME and Windows, so I want to make sure that the buttons are in the correct order for each platform. Does wxPython provide functionality that prevents me from doing a if platform.system() == 'Linux' kind of hack? The appearance of a dialog can change only if you use stock dialogs (like wx.FileDialog), if you make your

I'm looking for a cross platform file system watcher, similar to the FileSystemWatcher class in .NET. As it's for a daemon/service, I'm not keen on Qt's QFileSystemWatcher . I'd really like to avoid it as I don't want to have a dependency on Qt as my program is going to be a daemon. I've also seen a proposal for such a class to be included in Boost, but as far as I know such a class has not yet been included. Is there a cross platform C++ file system watcher? Qt is divided into modules , so using this feature doesn't mean you have to use the GUI library. QFileSystemWatcher is in QtCore , which

I'm currently working with the DJProject to put a browser into my Java Swing application. DJProject uses SWT to run and I have very little experience with SWT. I want to support Windows and Mac both 32bit and 64bit. I understand there is a swt.jar file for each of these platforms. I have all 4 swt.jar libraries added to my classpath as a library to the main application. My problem is when I try running the application on a Mac for example I get the error: Exception in thread "main" java.lang.UnsatisfiedLinkError: Cannot load 32-bit SWT libraries on 64-bit JVM how would I go about to

To my knowledge, Java's File class does not support to change the file's permission and last modified date. Is there any proper way to do this in a cross-platform style? I'm looking at the Java 6 documentation , and there is a setLastModified() method, as well as setReadable(...) and setWritable(...) and setExecutable(...) methods (all in the java.io.File class). So yes, there is a way... 来源： https://stackoverflow.com/questions/459622/how-to-change-the-files-permission-and-last-modified-in-java
