cross-platform

问题 I need to run Perl applications I develop on cygwin Windows on HP unix / Solaris hosts. I am not a superuser on the unix machines and I can't touch the default Perl module location nor can I install modules to the default Perl module location. Also the unix installation lacks most basic modules and I can't change that. For example, I have a Perl application that needs Expect which has native C compiled parts to it. How would I roll out this application to unix with its required dependencies

问题 I'm new to Flutter, was just wondering if it's possible. I've tried building the demo code using intellij with given instruction (https://flutter.io/setup/). It runs well on android device, but can't find the option to compile and run on my iOS device. 回答1: You can do your main development on Linux or Windows with Android Studio or Visual Studio Code. Then use git to move the code to macOS to test it with Xcode on an iOS simulator/device and deploy it to the App Store. You could do all

问题 I'm not looking for the usual answer like Web-services. I'm looking for a light solution to be run in the same machine. Edit: I'm looking for way in Java to call .NET methods 回答1: I believe Java can talk to COM and .NET can expose COM interfaces. So that may be a very light weight solution that doesn't require any 3rd party. There is also the option of using sockets to communicate between the programs which wouldn't require a heavy instance of IIS to be installed on the machine. 回答2: I am

问题 (by all mean do re-tag with the relevant technology: I don't know which ones they are :) I'll probably come later with more detailed questions, about specific details but for now I'm trying to grasp the "big picture": I'm looking for a way to enumerate "real visible windows" on Windows. By "real visible window" I mean just that: what a user would call a "window". I need a way to get a list of all these visible windows, in Z-order. Note that I do really need to do that. I've already done it on

问题 I have a C library, which I build as a shared object for Linux and a DLL for Windows with MinGW32. The API depends on a couple of data files (statistical models) which I'd really like to roll in with the SO/DLL so that deployment is just one file. It looks like I can achieve this for Windows with a "resource file" compiled with windres , but then I've got to write a bunch of resource-handling code for Windows, and I'm still stuck with the files on Linux. Is there a way to achieve the same

问题 Is there a way to modify the PATH environment variable in a platform independent way using python? Something similar to os.path.join() ? 回答1: You should be able to modify os.environ . Since os.pathsep is the character to separate different paths, you should use this to append each new path: os.environ["PATH"] += os.pathsep + path or, if there are several paths to add in a list: os.environ["PATH"] += os.pathsep + os.pathsep.join(pathlist) As you mentioned, os.path.join can also be used for

问题 Is there a way to shutdown a computer using a built-in Java method? 回答1: Create your own function to execute an OS command through the command line? For the sake of an example. But know where and why you'd want to use this as others note. public static void main(String arg[]) throws IOException{ Runtime runtime = Runtime.getRuntime(); Process proc = runtime.exec("shutdown -s -t 0"); System.exit(0); } 回答2: Here's another example that could work cross-platform: public static void shutdown()

问题 This question already has answers here : Platform independent size_t Format specifiers in c? (3 answers) Closed 2 years ago . How do you write code to compile cross-platform without warnings. For example, I don't get warnings on x64 platform, but I do on ARM (raspberry PI): warning: format ‘%lu’ expects argument of type ‘long unsigned int’, but argument 5 has type ‘size_t {aka unsigned int} Needless to say I don't want to disable warnings. More examples and scenarios: warning: format ‘%lu’

问题 I would like to generate a Static Library file in Windows using MSVC / IXX which is macOS and Linux compatible. I'm using C (Let's say C99 ) and the functions are really simple. For example: void AddArray(float* mA, float* mB, float* mC, int numElements){ int ii; for(ii = 0; ii < numElements; ii++){ mC[ii] = mA[ii] + mB[ii]; } } Is there a way to build the Library only once on Windows and use it everywhere? If not on windows, could it be done on Linux and work on Windows and macOS? The idea
