Eclipse can't find index libraries of GCC or G++

eclipse gcc g++ eclipse-cdt

Solution 1

I had a similar problem with the HelloWorld example. "namespace Std" and "cout" gave a "not resolved" error. I fixed this by simply restarting eclipse. Seems it does not recognize all include paths after a fresh installation / project creation.

Solution 2

Try restart eclipse, clean all, and recompile every target.

Solution 3

I managed to get rid of the unresolved inclusion error, under the project properties C/C++ General -> Paths and Symbols, includes tab add a new a directory and choose /usr/include/c++/4.6.1

Now I don't have the unresolved warning but have all the Symbol could not resolved Ex:

#include <iostream>                //
#include <stack>                   //these 3 lines are ok
using namespace std;               //

list<int> newList;                 //get Symbol 'list' could not be resolved
cout<<"message"<<endl;             //the same for 'cout' and 'endl'

It can build and debug just fine, but what is the point of having and IDE if it won't give you any help while coding

I have the following code which works well.

The code is to display all the data from the database in input text field format. User is able to edit and update the details by clicking the update button at the end of each row to update the specific row.

Instead of clicking the update buttons one by one (if user wants to edit and update more than one row), now I would like to create a hyperlink which will update ALL the data at once.

The problem now is I dunno how to pass the value of $_post to the "update.php" since I already have

<form name="form1" action="submitAction.php" method="post">

I am not sure is it possible to do so. Or are there any other alternative ways?

<html>
<script language="javascript" >
<!-- hide
function submitRequest(id) {
document.forms[id].submit();
}
// end hide -->
</script>

<!-- The Javasript (Onclick) to Remove the Readonly Attribute-->
<script language="JavaScript">
  function removeAlignment(id){
   document.getElementById("ProjectName_"+id).removeAttribute("readonly",0);
   document.getElementById("DeviceType_"+id).removeAttribute("readonly",0);
  }
</script>

<body>
<?php

$counter=1;
//Connecting and Accessing the Database 
$con = mysql_connect("localhost","root","");
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }

mysql_select_db("Project", $con);

$result = mysql_query("SELECT * FROM Project where status='Ongoing'");

?>

It would help to change the language of messages gcc LC_MESSAGES=C gcc

you can try to install g++ youtu.be/wl75o1Yc218 sometimes it happen based on compiler issue.

That is not a smart thing to do. Search engines for example tend to visit every url on a page, which will result it to update everything when it visits this page.

Yes, but in a back office or in a logged page it's not a problem

It's still a hack, and not where GET requests are meant for. It is asking for all sorts of problems. Use POST requests for actions that have consequences.

W3C rules ! ^^ so the solution for his problem could be a form with hidden input ?
