cross-platform

问题 As the title indicates, are there any C/C++ bytecode compilers/interpreters? I'm writing an application in an interpreted language that depends on certain libraries that are fully cross-compilable (there are no special flags to indicate code changes during compilation for a certain platform) but are written in C and C++. Rather than shipping n-platform-specific-libs with each platform, it would be nice to ship one set of libs which are interpreted by one platform specific interpreter.

问题 I've been searching for a while for an answer to my question: Does negative z-index have any side effects And I've already asked before here: Does negative z-index affect performance or compatibility? but it doesn't get enough attention (may be because I mixed things a little bit) And I wanted to try and asked in a other way. I am developing a web application for cross platforms (different browsers, devices), and sometimes I am in need to use a negative value for the z-index property, but I'm

问题 I am looking for a c++ library that can connect to and communicate with serial port devices. I need one that can be used on windows and linux. I have found "serialib" already but this has no feature for enumerating the available ports. So I either need a cross platform "port enumerator" library or a whole new cross platform serial port library. Does anyone know of a good one? Thanks, Dan. 回答1: http://wjwwood.io/serial/ https://github.com/wjwwood/serial This is a cross-platform serial port

问题 I'm writing some C++ code that will have to send data over TCP/IP. I want this code to be portable on Linux/Windows/Osx. Now, as it is the first time I write portable network code, I basically need some simple functions to add to certain objects like: class myclass{ ...member... public: string serialize(){ std::ostringstream out(); out << member1; out << member2; out << member3; return out.str(); } } ... which is all I need for now. Anyway I started reading ostringstream related docs and

问题 i am wondering if there is any way i can create an app that starts as a desktop application, for personal use for now. and since desktop applications can work with my HDD files which i may want to manage but don't feel secure throwing them onto a web server. but what i think i may want to do in the future is port the app to the web since that is where i think is the future of applications to come. web apps are available everywhere eg. web apps can be used on smart phones etc. facilitate team

问题 On Mac and Gnome, native applications use an application preferences dialog that immediately applies the chosen settings as they are selected. On Windows and (I think) KDE, preferences are applied only when an "Apply" or "OK" button is pressed. Are there any built-in Qt goodies to do this for you, or do you have to include several #ifdef 's in the dialog code to handle this ( Q_WS_WIN , Q_WS_MAC , Q_WS_X11 )? If you have done something like this before (even using #ifdef 's), could you share

问题 Is there a User-Agent-String parsing plugin or middleware that you can recommend. Right now I am using django-smartagent, but its dictionary is not complete and not updated very often. 回答1: The browscap files can be read by the pythong ConfigParser library and are updated regularly. http://browsers.garykeith.com/downloads.asp This is a module that shows using ConfigParser to read, from a older djangosnippet posting (267) slightly modified version to allow for easier 'finding' of the browscap

问题 In our development environment we use Windows, Mac, and Linux. I am having trouble when it comes to the commit -> pull -> push work flow. The problem is end of line characters. If someone makes an edit on Mac and some one else makes an edit on Windows they conflict when pulling. The diff shows the entire file as different because the line endings have changes. So my question is how can I setup all environments to convert all line endings to just LF when committing. And when pulling, don't

问题 I'm using sqlite to do an index of a proprietary file, and the database will be accessed with multiple threads (using different sqlite handles) for reading and writing. I know that sqlite locks the file in order to provide concurrency for readers/writers, and depends on the OS file api for locking. This is all fine on windows and linux, but on solaris and hpux I am less confident regarding how advisory locking works there. Does anyone have any idea how well sqlite works regarding concurrency
