objective c - How can I share code across static libraries without duplicate symbol errors? -

September 15, 2015

I am new to creating stable libraries and I would like to create 2 (+) libraries, each of which has unique code and Some of the shared codes are my intention that other projects can link to one or more of these stable libraries.

  UTHLH / M & LT; - Shared Implant H / M & LT; - Unique ImplTwo.h / m for 'ImplOn' - Unique to 'ImplTwo'    I am using XCode and libraries to  Util.m  and  ImplOne. M  In the case, and  Util.m  and  ImplTwo.m  in another.  
 The problem is that I can not use these libraries together because they have duplicate symbols. What is a better architecture for this situation?   
 
  I think the clean alternative would be to create a separate library  Utills.h / The drawbacks for m  are that your users will need to link to  utils  with  implone  and / or  impltwo  And it is necessary to compile both libraries with  utils  in order to link  impoone  and  impltwo  in return , Sources of libraries Nice and clean living.  
 To avoid the linkir errors, an option macros must be used to change the function and variable names in  utils . The most important result is code repeat: both  implone  and  impltwo  will link the code of the same code under different names. The second is a readability: it will be a great loss, because in the  utils , each reference to a function will need to be wrapped in a macro, it makes the second approach dirty, so I definitely have the  utils  will recommend making a separate library.

apache - How to do an URL rewrite that works with a
pre-existing .htaccess file? -



    I have a platform that is currently available through the URL:    Www.websitecom / index.php? App = forum    Instead, I want people to be able to go here:      & lt; Ifmodule mod_rewrite.c & gt; Option - Multi Views RewriteEngine RewriteBase / RewriteCond on% {REQUEST_FILENAME}! -f Rewrite Convert% {REQUEST_FILENAME}! -d rewriteable /index.php [L] & lt; / IfModule & gt;    It seems that it should be possible, but I'm not sure how to do it.   Thank you!      This has not been tested, but something like that should be done. Add it before the first Rev.Directivity.    RewriteRule ^ forum $ /index.php?app=forums    Alternatively, you redirect from a 301 / forum to index.php URL .   By doing this:    301 / redirect the forum "http://www.website.com/index.php?app = forum    However, it seems that you want to make a proper rewrite, so the first option is better,     






c# - EventSource's response has a MIME type ("text/html") that is
not "text/event-stream" -



    When I try to hook my controller to EventSource, it keeps saying:    EventSource Response contains a MIME type ("text / html") that is not "text / event-stream" canceling connection.    I have created the following class to help in handling a handle and preparing the reaction. In this class I believe that I set the  text / event-stream  according to the response.    public class ServerSentEventResult: ActionResult {public representative string GetContent (); Public GetContent Content {get; Set; } Public int version {get; Set; } Public Override Zero ExecuteResult (Controller Context Reference) {if (context == null) {New argument NullException ("Reference"); } If (this.

    I want to create an APK with some big configurations with an XML file.  I want to know if there is any method which can control the APK's building process or encoding at our source, there is no way to create APK with our source from our source, with a slight variation based on our SQF XML file. . Or any other way to create an APK file    When the app is running, I do not want to read my config file every time, I have to include a change in the application        If you want to manually create your application:    If you are developing in Eclipse, then the ADT plugin The enhanced project as you make changes to the source code. Eclipse automatically produces an .apk file in the project's bin folder, so you do not need to do anything extra to generate .apk.   If you are developing in a non-eclipse environment, then you create your project with the Generated Build.xml Ant file in the project directory that creates ant file calls which automatically targets you for Call the buil...
