cross-platform

问题 I wrote a script for a Linux bash shell. One line takes a list of filenames and sorts them. The list looks like this: char32.png char33.png [...] char127.png It goes from 32 to 127. The default sorting of ls of this list is like this char100.png char101.png [...] char32.png char33.png [...] char99.png Luckily, there is sort , which has the handy -V switch which sorts the list correctly (as in the first example). Now, I have to port this script to OSX and sort in OSX is lacking the -V switch.

问题 I need some mechanism reminiscent of Win32 reset events that I can check via functions having the same semantics with WaitForSingleObject() and WaitForMultipleObjects() (Only need the ..SingleObject() version for the moment) . But I am targeting multiple platforms so all I have is boost::threads (AFAIK) . I came up with the following class and wanted to ask about the potential problems and whether it is up to the task or not. Thanks in advance. class reset_event { bool flag, auto_reset; boost

问题 We are developing a cross platform app on a PCL, but for the time being we are only using android devices for testing. Our concern is that its taking about 6 to 8 seconds (depending on which device we test it) to start the app, which is very slow. After placing a few breakpoints we saw that the timing is consumed pretty evenly. We did notice this particular parts took longer: 1s before reaching onCreate() on MainActivity (there's a splash screen before which only has one image and a

问题 How get current ip-address for Xamarin.Forms ( Cross Platform) ? WifiManager I can't use and can't WifiManager include? 回答1: public string MyIp; foreach (IPAddress adress in Dns.GetHostAddresses(Dns.GetHostName())) { MyIp = "IP Adress: " + adress.ToString(); SettingsTab.IP_Adress = MyIp; break; } 回答2: try to do this: public static string GetIPAddress() { var AllNetworkInterfaces = Collections.List(Java.Net.NetworkInterface.NetworkInterfaces); var IPAddres = ""; foreach (var interfaces in

问题 I'm using unity 5.3 and I'm trying to change the Rendering Order of two overlayed cross platform controls which each reside in their own canvas. In previous versions you could bring the window into focus using GUI.FocusWindow(0); However this does not work with the new system. I've also tried modifying the order in the editor window which has done nothing. Does anyone know how I can move a control to be on top of the other? 回答1: After doing some research I found the proper way to change the

问题 Im new to python, but I was thinking about making a program with python to give to my friends. They don't know much about computers so if I asked them to install python by them selves they couldn't do it, but what if I could make an installer that downloads some version of python that only has what is needed for my file to run and make an exe file that would run the .py file in its own python interpreter . I also did a Google search and saw the freezing applications I could use to make the

问题 OpenMP is supported in GCC which is cross-platform... but does that mean OpenMP is supported on all target platforms? Specifically, iOS and Android**... as phones/tablets move to quad-core, not using all the cores in games will be a huge disadvantage. ** As a non mobile-developer I don't know if you can write C++ apps for Android in the first place? 回答1: This is not necessarily the case. Example: http://groups.google.com/group/android-ndk/browse_thread/thread/a547eac5446035b4?pli=1 OMP is not

问题 I want to write a C++-Program that can interact/call Lua-scripts during execution. A key concept of the program is complete platform independence, but I seem to be unable to locate a Lua-build that actually offers something that. The Lua-builds I found so far are either based on environment-variables or specific libraries like .lib , .dll or .so . The official Lua-source from lua.org also is not what I'm looking for as it defines a main-function… Is there a simple - best case would be

问题 I can get the home with os.path.expanduser("~") but is there a standard way to get the config directory? Like ~/.config in most unices, or the value of $XDG_CONFIG_HOME in (recent?) Linux and C:\Users\<user>\AppData\Local\Roaming in Windows), etc 回答1: You can take advantage of python third party library appdirs which does all the heavy lifting for you across multiple platforms ( Windows, Linux & Mac ) 来源： https://stackoverflow.com/questions/31866115/is-there-a-standard-way-to-get-the-user
