libraries

问题 Is it possible to load an library from within a library in code igniter? If I do $this->validator = $this->CI->load->library('validators/'.$params['validator']); from within another library $this->validator is NULL. Why would this be? 回答1: Check out the CI_Loader class's signature for the library() method you refer to: /** * Class Loader * * This function lets users load and instantiate classes. * It is designed to be called from a user's app controllers. * * @access public * @param string

问题 I'm writing a simple Erlang program that requests an URL and parses the response as JSON. To do that, I need to use a Library called Jiffy. I downloaded and compiled it, and now i have a .beam file along with a .app file. My question is: How do I use it? How do I include this library in my program?. I cannot understand why I can't find an answer on the web for something that must be very crucial. Erlang has an include syntax, but receives a .hrl file. Thanks! 回答1: You don't need to include

问题 Right, well. First time I'm actually using Java to fix a problem. I bought a new headphone set called Sennheiser 120 HD; but there's an issue. If there isn't a constant emission of audio then the base for the headphones will eventually time out and turn off. The headphones are spammed with static, which is horrible on the ears. The solution to this for me currently is playing music 24/7 to prevent the static of death. Maybe I'm weird, but I don't want to listen to music 24/7. I believe a

问题 I have many external libraries and SDKs in my project. And some of them does not support bitcode . So I have to disable bitcode . But some libraries like ParseCrashReporting , does require it to symbolicate the crash reports. I want to disable and enable bitcode for specific libraries. How I can achieve that? Is it even possible? Thanks 回答1: You can't. The library itself has to be built with support of bitcode. However, in case you have to ship you app right now and you don't have time for

问题 I've always wondered how the dependencies are managed from a programming language to its libraries. Take for example C#. When I was beginning to learn about computing, I would assume (wrongly as it turns out) that the language itself is designed independently of the class libraries that would eventually become available for it. That is, the set of language keywords (such as for , class or throw ) plus the syntax and semantics are defined first, and libraries that can be used from the language

问题 I have a project whose output is a library (.lib). The project depends on a third party library (also a .lib). In order to avoid projects built on top of my library having to worry about this third party dependency, I have used the librarian to include it in mine (Project Properties > Librarian > General > Additional Dependencies). However, when I build a separate executable project which links to my library, I get a bunch of warnings along the lines of: MyProject.lib(someThirdPartyObjectFile

问题 I have found the code which links against of 'g2c' library. Why do I need it? Just would like to understand why it might be important and what it does in general. Thanks! 回答1: What is GNU Fortran? g77 consists of several components: A modified version of the gcc command, which also might be installed as the system's cc command. (In many cases, cc refers to the system's “native” C compiler, which might be a non-GNU compiler, or an older version of gcc considered more stable or that is used to
