All you need to do instal install package libxml2-dev for example:

    sudo apt-get install libxml2-dev

On CentOS/RHEL:
    
    sudo yum install libxml2-devel

For the latest versions it is needed to install libxml++2.6-dev like that:

    apt-get install libxml++2.6-dev

 

I had the same issue when I used a DockerFile. 
My Docker is based on the php:5.5-apache image.

I got that error when executing the command `RUN docker-php-ext-install soap`

I have solved it by adding the following command to my Dockerfile:

```
RUN apt-get update &amp;&amp; apt-get install -y libxml2-dev

Ubuntu, Debian:

    sudo apt install libxml2-dev

Centos:

    sudo yum install libxml2-devel



this solution it gonna be ok on Redhat 8.0

sudo yum install libxml2-devel

OpenSuse

&quot;**sudo zypper install libxml2-devel**&quot;

It will install any other dependencies or required packages/libraries

I am trying to set a Spring Boot applications context root programmatically. The reason for the context root is we want the app to be accessed from `localhost:port/{app_name}` and have all the controller paths append to it. 

Here is the application configuration file for the web-app.

    @Configuration
    public class ApplicationConfiguration {

      Logger logger = LoggerFactory.getLogger(ApplicationConfiguration.class);

      @Value(&quot;${mainstay.web.port:12378}&quot;)
      private String port;

      @Value(&quot;${mainstay.web.context:/mainstay}&quot;)
      private String context;

      private Set&lt;ErrorPage&gt; pageHandlers;

      @PostConstruct
      private void init(){
          pageHandlers = new HashSet&lt;ErrorPage&gt;();
          pageHandlers.add(new ErrorPage(HttpStatus.NOT_FOUND,&quot;/notfound.html&quot;));
          pageHandlers.add(new ErrorPage(HttpStatus.FORBIDDEN,&quot;/forbidden.html&quot;));
      }

      @Bean
      public EmbeddedServletContainerFactory servletContainer(){
          TomcatEmbeddedServletContainerFactory factory = new TomcatEmbeddedServletContainerFactory();
          logger.info(&quot;Setting custom configuration for Mainstay:&quot;);
          logger.info(&quot;Setting port to {}&quot;,port);
          logger.info(&quot;Setting context to {}&quot;,context);
          factory.setPort(Integer.valueOf(port));
          factory.setContextPath(context);
          factory.setErrorPages(pageHandlers);
          return factory;
      }

      public String getPort() {
          return port;
      }

      public void setPort(String port) {
          this.port = port;
      }
    }

Here is the index controller for the main page. 

    @Controller
    public class IndexController {

      Logger logger = LoggerFactory.getLogger(IndexController.class);
      
      @RequestMapping(&quot;/&quot;)
      public String index(Model model){
          logger.info(&quot;Setting index page title to Mainstay - Web&quot;);
          model.addAttribute(&quot;title&quot;,&quot;Mainstay - Web&quot;);
          return &quot;index&quot;;
      }

    }


The new root of the application should be at `localhost:12378/mainstay`, but it is still located at `localhost:12378`. 

What am I missing that is causing Spring Boot to not append the context root before the request mapping?


Add context path to Spring Boot application

I am trying my very first formal python program using Threading and Multiprocessing on a windows machine. I am unable to launch the processes though, with python giving the following message. The thing is, I am not launching my threads in the __main__ module. The threads are handled in a separate module inside a class.


**EDIT**: By the way this code runs fine on ubuntu. Not quite on windows

    RuntimeError: 
                Attempt to start a new process before the current process
                has finished its bootstrapping phase.
                This probably means that you are on Windows and you have
                forgotten to use the proper idiom in the main module:
                    if __name__ == &#39;__main__&#39;:
                        freeze_support()
                        ...
                The &quot;freeze_support()&quot; line can be omitted if the program
                is not going to be frozen to produce a Windows executable.

My original code is pretty long, but I was able to reproduce the error in an abridged version of the code. It is split in two files, the first is the main module and does very little other than import the module which handles processes/threads and calls a method. The second module is where the meat of the code is.

    extractor = parallelTestModule.ParallelExtractor()
    extractor.runInParallel(numProcesses=2, numThreads=4)

I am trying to get Composer do download the latest commit for the Behat/MinkSelenium2Driver package. That particular repo only has a master branch. I have tried every method I can think of, including deleting the files and letting it pull them back in, to get it to work but it doesn&#39;t.

How would I get it to pull in latest committed files or at least those from the commit I list below?

Specifically I want to get this commit:
https://github.com/Behat/MinkSelenium2Driver/commit/2e73d8134ec8526b6e742f05c146fec2d5e1b8d6

How do I get Composer to download the latest commit in the master branch from GitHub for a package?

I&#39;m in the process of converting one of our web applications from CodeIgniter to Laravel. However at this moment we don&#39;t want to add the `updated_at` / `created_at` fields to all of our tables as we have a logging class that does all this in more depth for us already. 

I&#39;m aware I can set `$timestamps = false;` in:

    Vendor\laravel\framework\src\illuminate\Datebase\Eloquent\Model.php

However I&#39;d rather not change a core file for Laravel, or have everyone of my models have that at the top. Is there any way to disable this elsewhere for all models?

Current Codes:

    &lt;?php

      // See the AND operator; How do I simplify/shorten this line?
      if( $some_variable !== &#39;uk&#39; &amp;&amp; $some_variable !== &#39;in&#39; ) {
    
        // Do something
    
      }

    ?&gt;

And:

    &lt;?php
    
      // See the OR operator; How do I simplify/shorten this line?
      if( $some_variable !== &#39;uk&#39; || $some_variable !== &#39;in&#39; ) {
    
        // Do something else
    
      }
    
    ?&gt;

Is there a simpler (i.e. shorter) way to write the two conditions?

**NOTE:** Yes, they are different, and I am expecting different ways to shorten the codes.

Simpler way to check if variable is not equal to multiple string values?

I am developing Windows Phone 8 app. I want to upload SQLite database via PHP web service using HTTP POST request with MIME type multipart/form-data &amp; a string data called &quot;userid=SOME_ID&quot;. 

I don&#39;t want to use 3rd party libs like HttpClient, RestSharp or MyToolkit. I tried the below code but it doesn&#39;t upload the file &amp; also doesn&#39;t give me any errors. It&#39;s working fine in Android, PHP, etc so there&#39;s no issue in web service. Below is my given code (for WP8). what&#39;s wrong with it?

I&#39;ve googled and I&#39;m not getting specific for WP8

        //var file = await ApplicationData.Current.LocalFolder.GetFileAsync(DBNAME);

How to upload file to server with HTTP POST multipart/form-data?

This is my first work with Symfony 2. All I am trying to do here is whenever the user clicks on the submit button he will go to another page.

But my index page isn&#39;t loading. They are saying there is something wrong with my routing file, specifically:

&gt; A YAML file cannot contain tabs as indentation

I don&#39;t know what I have done wrong. Here is my routing file.

    community_online_shop_homepage:
        pattern: /
        defaults: { _controller: CommunityOnlineShopBundle:Page:index }
    _login:
    	pattern: /login
    	defaults: { _controller: CommunityOnlineShopBundle:Page:login}


A YAML file cannot contain tabs as indentation

I have a problem understanding this piece of code:

    int[] it = new int[][]{{1}}[0];

Why is it compileable, and how can I understand such a declaration?


Two dimensional array initializer followed by square brackets

I encountered an odd situation where appending `OPTION (RECOMPILE)` to my query causes it to run in half a second, while omitting it causes the query to take well over five minutes.

This is the case when the query is executed from Query Analyzer or from my C# program via `SqlCommand.ExecuteReader()`. Calling (or not calling) `DBCC FREEPROCCACHE` or `DBCC dropcleanbuffers` makes no difference; Query results are always returned instantaneously with `OPTION (RECOMPILE)` and greater than five minutes without it. The query is always called with the same parameters [for the sake of this test].

I&#39;m using SQL Server 2008.

I&#39;m fairly comfortable with writing SQL but have never used an `OPTION` command in a query before and was unfamiliar with the whole concept of plan caches until scanning the posts on this forum. My understanding from the posts is that `OPTION (RECOMPILE)` is an expensive operation. It apparently creates a new lookup strategy for the query. So why is it then, that subsequent queries that omit the `OPTION (RECOMPILE)` are so slow? Shouldn&#39;t the subsequent queries be making use of the lookup strategy that was computed on the previous call which included the recompilation hint?

Is it highly unusual to have a query that requires a recompilation hint on every single call?

Sorry for the entry-level question but I can&#39;t really make heads or tails of this.

**UPDATE: I&#39;ve been asked to post the query...**

    select acctNo,min(date) earliestDate 
    from( 
    	select acctNo,tradeDate as date 
    	from datafeed_trans 
    	where feedid=@feedID and feedDate=@feedDate 
    
    	union 
    
    	select acctNo,feedDate as date 
    	from datafeed_money 
    	where feedid=@feedID and feedDate=@feedDate 
    
    	union 
    
    	select acctNo,feedDate as date 
    	from datafeed_jnl 
    	where feedid=@feedID and feedDate=@feedDate 
    )t1 
    group by t1.acctNo
    OPTION(RECOMPILE)

When running the test from Query Analyzer, I prepend the following lines:

    declare @feedID int
    select @feedID=20
    
    declare @feedDate datetime
    select @feedDate=&#39;1/2/2009&#39;

When calling it from my C# program, the parameters are passed in via the `SqlCommand.Parameters` property.

For the purposes of this discussion, you can assume that the parameters never change so we can rule out sub-optimal parameter smelling as the cause.




OPTION (RECOMPILE) is Always Faster; Why?

Despite specifying JDK 1.7 in all project settings (including in `File -&gt; Project Structure -&gt; Project :: Project SDK`), the following error is produced by `IntelliJ 13` when trying to compile some simple Java 7 code which does use the diamond operator:

    java: diamond operator is not supported in -source 1.5
    (use -source 7 or higher to enable diamond operator)

Is there any other place in the configuration where the expected `-source 7` option should be enabled?

IntelliJ IDEA 13 uses Java 1.5 despite setting to 1.7

GCC, MSVC, LLVM, and probably other toolchains have support for link-time (whole program) optimization to allow optimization of calls among compilation units.

Is there a reason not to enable this option when compiling production software?


Is there a reason why not to use link-time optimization (LTO)?

I am wondering why is the following code allowed in Java, without getting compilation error?
In my opinion, this code breaks method signature by not returning any `String`.
Could someone explain what I&#39;m missing here?  

    public class Loop {

      private String withoutReturnStatement() {
        while(true) {}
      }

      public static void main(String[] a) {
        new Loop().withoutReturnStatement();
      }
    }
