cross-platform

问题 Running IDE-Machine Windows 10 with Visual Studio 2019. Target-System for debugging is a Ubuntu 18.04. Using CMake available in Visual Stdio addons. Test software is the soem lib, with the simple_test programm, wich already leads to the issue (https://github.com/OpenEtherCATsociety/SOEM). After passing the eth-interface to the built programm, it stops with cause it can't get root. Already tried to pass sudo in the launch.vs.json and also pipe sudo the programm. Tried to change the access to

问题 I'm trying to accomplish the following with a Qt (C++) app, cross OS. Upon running the program a new window pops up, a fullscreen QWidget. Now I want this to be see-through/transparent, so the user won't actually see it. On this 'layer' a user can drag his/her mouse to draw a (red) rectangle to select an area which is - when the mouse is released - taken a screenshot of. The problem: The issue lays in the whole transparent layer thing since this doesn't appear to work well cross OS. Because

问题 What are techniques for determining running OS in assembly language at runtime? If there are direct ways to determine this, that'd be awesome. I was also thinking of how there are tricks in Javascript to determine what browser you're running in... Are there similar techniques for determining OS or even CPU arch in a low level language like Intel assembly? Thanks, Chenz 回答1: CPU architecture will be next-to-impossible to determine. Machine code differs greatly between CPU architectures, and so

问题 I am developing a simple standalone, graphical application in python. My development has been done on linux but I would like to distribute the application cross-platform. I have a launcher script which checks a bunch of environment variables and then sets various configuration options, and then calls the application with what amounts to python main.py (specifically os.system('python main.py %s'% (arg1, arg2...)) ) On OS X (without X11), the launcher script crashed with an error like Could not

问题 I'm trying to design a custom type that can be used in APIs which need window handles or other kinds of pointers, and which will work for all systems VBA can run on. Here's what I've got: #If (Win64 = 1) And (VBA7 = 0) Then Public Type LongLong '64-bit systems pre-VBA7 wouldn't have had LongLong LoPart As Long HiPart As Long End Type #End If Public Type Pointer 'could alternatively make a LongPtr type for pre VBA7 systems only #If VBA7 Then Address As LongPtr 'should always be correct right?

问题 My PC has two devices working like keyboard, the normal keyboard and a HID ( H uman I nterface D evice) input device (it's a remote control). I want separate the input from keyboard and from remote, capturing only the remote control. How can I write a program in C/C++ to do this task? It's not a easy task because this program is operating system dependent. I need it for Windows, but if someone knows how to do it for Linux, I would appreciate that too. 回答1: On Windows XP and later you can use

问题 I use Jenkins a lot within our organization, for building and deploying projects. I have a set of bash scripts fine-tuned to be modular and reusable for multiple projects. These are triggered by Jenkins during deploy jobs. The problem comes when the deployment environment changes from Linux to Windows. The bash scripts are no longer an option (installing cygwin on multiple/random deployment machines is also not an option). I could rewrite all the bash scripts in batch, but that would result

问题 This question already has answers here : Closed 8 years ago . Possible Duplicate: What's the best CRLF handling strategy with git? I'm currently working on a project where almost every time I merge master into my branch, I get merge conflicts where git says the entire file has changed. Often when I compare these files using Notepad++'s compare tool, it reports that only a couple of lines have actually changed and often it shouldn't even result in a conflict. For a while I've simply put up

问题 In linux, I can use lsof -i as in the following function: def FindProcessUsingPort(portnum): import os fp = os.popen("lsof -i :%s" % portnum) lines = fp.readlines() fp.close() pid = None if len(lines) >= 2: pid = int(lines[1].split()[1]) return pid Is there a cross-platform way to figure this out? As a relevant reference, once I know the process id, the psutil library is very nice and lets me determine all sorts of useful process information for it in a cross-platform way. I just can't get
