Are Golang binaries portable?

问题 Suppose I'm a primarily Linux user, but I'm developing an application in Go that I want to be cross platform. I've searched around, but I can't seem to find information to absolve the following: If I go install a binary on my amd64 Ubuntu system, will it also work on anyone else's 64-bit Ubuntu/Debian system? How can I use go install to build an x86_64 binary that will also run out-of-the-box on 32-bit Debianlikes? If I must use Windows to make a binary which will run on Windows, how can I

i am trying to create a embedded browser using the JavaFX2.1 by using jdk1.6 update 32 however it looks like that all the programs are not working because of jdk1.6u32. but at the requirement its clearly mention that JavaFx2.1 will work with the jdk1.6update 32. Does anybody knows what is the reason? I am right now trying to run the sample programs which comes with javaFx2.1 and the below one http://docs.oracle.com/javafx/2/swing/SimpleSwingBrowser.java.htm while executing the above program with jkd1.6u32 and jdk1.7u4 program compiles and executes but doesn't display any page. I saw the below

GLFW Toggling Windowed-Fullscreen Mode

阅读更多关于 GLFW Toggling Windowed-Fullscreen Mode

问题 I am using GLFW and I would like to know how to toggle full-screen windowed mode. Not changing the resolution, but instead setting the window to be on top and without decoration. If GLFW is not capable of doing this, then what cross platform library do you suggest to achieve this? 回答1: You can tell glfw to open your window fullscreen. glfwOpenWindow( width, height, 0, 0, 0, 0, 0, 0, GLFW_FULLSCREEN ) As far as I know you would have to close and reopen this window to switch between a window

Set tkinter icon on Mac OS

阅读更多关于 Set tkinter icon on Mac OS

问题 I am trying to change the icon that appears on my tk application for Mac OS. The last time I checked this code worked for windows. The goal is for this solution to work across all platforms. root = tk.Tk() app = Application(master=root) app.master.iconbitmap("my_icon.ico") app.mainloop() The code is adding the default icon for a .pdf file which is not what I intended. The path to the my_icon.ico is correct. Why won't this work for Mac OS? Is there an ultimate solution that will work cross

“Illegal instruction” when cross-compiling Qt 4.7

阅读更多关于 “Illegal instruction” when cross-compiling Qt 4.7

问题 I'm struggling with this problem for more than a week now, and still can't find a solution... I'm trying to cross-compile Qt 4.7 embedded open-source version for an ARM device. The build process itself completes without problems, but the generated binaries seem to contain instructions that the processor does not understand. Build host is Debian 5 (Etch) on i386 (running on a virtual PC) The device is a Trimble Nomad handheld with an ARM processor (see full cpuinfo and kernel configuration) I

cordova phonegap using external web page in app while maintaining header/footer (for navigation)

阅读更多关于 cordova phonegap using external web page in app while maintaining header/footer (for navigation)

问题 So far I have tried inappbrowser and iframes. Iframes work, but I have encountered a couple of app-breaking bugs in the implementation I am using with iframes. Is there a more native-like solution for displaying external web pages inside of phonegap while still maintaining your apps navigation, such as a header with a side scrolling menu? 回答1: I believe, the easiest approach is to go with cordova themablebrowser plugin which simplifies the implementation and helps in ease of development and

Case-insensitive File.equals on case-sensitive file system

阅读更多关于 Case-insensitive File.equals on case-sensitive file system

问题 I have a file path in String form. In Java, I need to determine if that file exists on the file system (and our code needs to be cross-platform as it runs on Windows, Linux and OS X). The problem is that the case of the file path and the file itself may not match, even though they do represent the same file (presumably this is because they originated on Windows and the discrepancy was not noticed). For example, I have a file path of "ABC.txt". A file called "abc.txt" exists on the file system

Which version of windows 7 should I buy to run under vmware fusion for web dev?

阅读更多关于 Which version of windows 7 should I buy to run under vmware fusion for web dev?

问题 Does it make a difference? All I'll be doing (for the most part) is running different browsers. I would think the most stripped down one possible would be best. Update: My dev box is a MacBook Pro (2010) with 8G ram, 2.4 GHz processor running Lion. 回答1: Ordinary Windows 7 installations are shipped with a full load of crap. Even the cleanest installs have a size of at least 10 GB. For that reason, I recommend to only use Windows 7 if you want to test IE9+ (which requires Vista+). The following
