问题 How portable is weak linking? #pragma weak my_symbol I see that question: how-to-make-weak-linking-work-with-gcc discusses how to get it working. But is there a good way to do this such that gcc is not required? What is the difference between weak linking and guarding the declartion with an #ifdef? #ifndef my_weak_fn void my_weak_fn(){/* Do nothing */ return;} #endif 回答1: #pragma is, by definition, not portable. And weak linking is done at link time (surprisingly enough). It allows a function

问题 How can I set up the < localRepository > tag with an environment user var. I tried this path: %myRepo%/repo but it doesn't works (myRepo=C:/maven/repo). I can't use an absolute path for portability issues but I can setup %myRepo% to the correct place on each system in which the absolute path may vary but the /repo stays the same. Can someone help me? Thanks. Using windows. Maven 2.2.1. 回答1: You can use ${env.HOME} to refer to the environment variable %HOME%, and similarly any other

问题 I have some Django middleware code that connects to a database. I want to turn the middleware into a reusable application ("app") so I can package it for distribution into many other projects, without needing to copy-and-paste. I don't understand where a reusable application is supposed to configure itself. Since it's intended for redistribution I don't have the ability to write the central settings.py myself. Looking at the Django documentation I see there's settings.configure but it appears

问题 This question already has answers here : Who determines the ordering of characters (6 answers) Closed 5 years ago . I see nothing wrong with the following program, and this being non-portable is really confusing to me. According to the book by Mike Banahan (GBdirect C Book, Section 2.4.2), the following program is non-portable. Reason given is: Another example, perhaps. This will either print out the whole lower case alphabet, if your implementation has its characters stored consecutively, or

问题 Is there a portable wchar_t in C++? On Windows, its 2 bytes. On everything else is 4 bytes. I would like to use wstring in my application, but this will cause problems if I decide down the line to port it. 回答1: If you're dealing with use internal to the program, don't worry about it; a wchar_t in class A is the same as in class B. If you're planning to transfer data between Windows and Linux/MacOSX versions, you've got more than wchar_t to worry about, and you need to come up with means to

问题 I'm using __get_cpuid() to get info on the x86 and x86_64 processors my programs run on. With GCC on Linux and Mac OS, it seems to compile and run OK without include any header, but how portable is that? Would it work with other compilers? Should I include a header for that? 回答1: It has two leading underscores. Any leading underscore at all is a big hint that the variable or function is not portable. 来源： https://stackoverflow.com/questions/8407001/how-portable-is-get-cpuid

问题 Is there an mechanism or trick to run a function when a program loads? What I'm trying to achieve... void foo(void) { } register_function(foo); but obviously register_function won't run. so a trick in C++ is to use initialization to make a function run something like int throwaway = register_function(foo); but that doesn't work in C. So I'm looking for a way around this using standard C (nothing platform / compiler specific ) 回答1: If you are using GCC, you can do this with a constructor

问题 One of my favorite things about owning a USB flash storage device is hauling around a bunch of useful tools with me. I'd like to write some tools, and make them work well in this kind of environment. I know C# best, and I'm productive in it, so I could get a windows forms application up in no time that way. But what considerations should I account for in making a portable app? A few I can think of, but don't know answers to: 1) Language portability - Ok, I know that any machine I use it on

问题 Suppose I have this: <Window stuff Icon="Resources\myicon.ico"> If I run the program on Windows 7, it's fine. If I run it on Windows XP SP2, it crashes. Removing the Icon property, it works fine on Windows XP, but then it doesn't have my myicon on the Windows 7 taskbar or on the Window. Also, setting the application icon on the VS project menu doesn't work for W7, but works for XP. In summary: <Icon> = broken XP, ok W7 No <Icon> = ok XP, ugly W7 VS project icon option = doesn't work for W7,
