Eclipse 3.7.1
CDT 1.4.1
GCC 4.6.2

This is an example of a piece of C++11 code:

    auto text = std::unique_ptr&lt;char[]&gt;(new char[len]);

The Eclipse editor complains about:

    Function &#39;unique_ptr&#39; could not be resolved

The Makefile compilation works fine. How to make Eclipse stop complaining about these sort of errors?


How to enable C++11/C++0x support in Eclipse CDT?

I have the following boxes:

a) A Windows box with Eclipse CDT,  
b) A Linux box, accessible for me only via SSH.

Both the compiler and the hardware required to build and run my project is only on machine B.

I&#39;d like to work &quot;transparently&quot; from a Windows box on that project using Eclipse CDT and be able to build, run and debug the project remotely from within the IDE.

How do I set up that:

- The building will work? Any simpler solutions than writing a local makefile which would `rsync` the project and then call a remote makefile to initiate the actual build? Does Eclipse managed build have a feature for that?
- The debugging will work?
- Preferably - the Eclipse CDT code indexing will work? Do I have to copy all required header files from machine B to machine A and add them to include path manually?



Work on a remote project with Eclipse via SSH

When I try to build a program using `Eclipse CDT`, I get the following:

&gt; /mingw/lib/libmingw32.a(main.o):main.c:(.text+0x106):
&gt; undefined reference to `WinMain@16

Why is that? And, how can I solve this issue?


undefined reference to `WinMain@16&#39;

I set up CDT for eclipse and wrote a simple hello world C program:

    #include &lt;stdio.h&gt;
    
    int main(void){
        puts(&quot;Hello, world.&quot;);
    	return 0;
    }

The program builds and runs correctly, but eclipse keeps showing this yellow question mark by the side of inclusion statement that says `&quot;Unresolved inclusion: &lt;stdio.h&gt;&quot;` when I put mouse over it.

It doesn&#39;t affect running of the program but I find it rather annoying.

Does anyone have any idea how to remove it?

&quot;Unresolved inclusion&quot; error with Eclipse CDT for C standard library headers

I noticed that after installing cdt, Eclipse always loads the default workspace. The workspace listed in the `config.ini` in `osgi.instance.area.default`. Eclipse does not ask which workspace to open regardless if `Prompt for workspace on startup` is set or not.

How do I force Eclipse to ask which workspace to load on startup?

How do I remove the &quot;Quick Access&quot; text entry from Juno&#39;s CDT toolbar? I never use it and it consumes valuable space on my laptop screen.

Remove &quot;Quick Access&quot; entry in Eclipse Juno

EDIT: It turns out this really isn&#39;t specific to Eclipse Kepler. I had to use the same process for Eclipse Juno. The problem was that there seem to be missing steps in other posts answering this same question.

I&#39;m using Eclipse Kepler for C++ and I&#39;m trying to use C++11 and getting errors. When I compile I get the error

error: range-based-for loops are not allowed in C++98 mode

I&#39;ve followed the instructions from the post

https://stackoverflow.com/questions/9131763/eclipse-cdt-c11-c0x-support

and the solution given for Eclipse Juno isn&#39;t working. 

Different comments have suggested restarting eclipse and cleaning and rebuilding. That hasn&#39;t made a difference.

How to enable C++11 in Eclipse Juno/Kepler/Luna CDT?

I would like to make a cheat sheet presenting the most useful (and time saving) shortcut for Eclipse CDT (C++). 

Can you share what are the most useful shortcuts that you use in CDT?

Please, post only general shortcuts (available when doing C++) or CDT specific.


Most useful shortcut in Eclipse CDT

I&#39;m using Eclipse Helios on Ubuntu 10.04, and I&#39;m trying to install CDT plugin on it. I download it from here [here][1]. 

And then I go to **Install New Software** and select the zip file (*I don&#39;t extract it, just select the zip file*). And its ok, it installs, everything works fine, it shows optional features, *blah blah blah*.

And then I create a new HelloWorld project. And when I try to run it, it shows an error and says:

Launch failed. Binary not found.

Can anyone explain me how to fix it?

Thanks.

I have the eclipse CDT installed, and I would like to install Java development functionality (JDT) on top of my CDT installation. I&#39;ve been Googling from an hour but I can&#39;t figure out how to do this. 

What plugin do I need to install? What update site do I need to use?

Install Eclipse JDT on top of CDT

I&#39;m setting up a C++ project, on Ubuntu x64, using Eclipse-CDT.  I&#39;m basically doing a hello world and linking to a commerical 3rd party library.

I&#39;ve included the header files, linked to their libraries, but I still get linker errors.  Are there some possible problems here other than the obvious (e.g. I am 99% sure I&#39;m linking to the correct library).

 1. Is there a way to confirm the static libraries I am linking to are 64bit?
 2. Is there a way to confirm that the library has the class (and methods) I am expecting it to have?

Eclipse says:

&lt;pre&gt;

Using Eclipse and CDT to debug C++ code the variable windows is cumbersome and not very informative for types defined in the standard template library or in boost (e.g. shared_ptr).

Just an example how this may look like for an std::vector:

    bar	{…}
    	std::_Vector_base&lt;TSample&lt;MyTraits&gt;, std::allocator&lt;TSample&lt;MyTraits&gt; &gt; &gt;	
    		_M_impl	{…}	
    			std::allocator&lt;TSample&lt;MyTraits&gt; &gt;	{…}	
    			_M_start	0x00007ffff7fb5010	
    			_M_finish	0x00007ffff7fd4410	
    			_M_end_of_storage	0x00007ffff7fd5010	

Even if this information about the internals of those types may be useful, in almost any cases I would expect a clearer presentation here, i.e. a list of values for the std::vector. Are there any tools, plugins or other modifications around which can do this?

**EDIT**

The following solutions does not work for linux. I am using ubuntu 14.04, eclipse, g++, gdb.

I cant find a package gdb-python and linux does not use mingw

I&#39;m using Eclipse with C++ code via linked resources on Linux. The code analysis index seems to be corrupted (Goto definition lands the cursor close to, but not on, the definition) Refreshing resources doesn&#39;t fix it, neither does restarting Eclipse.

Is there a way to flush the index and rebuild it?

Clean Eclipse Index, it is out of sync with code

The error is as above. I have what should be all the necessary files include in the eclipse project:

    /usr/include/c++/4.6
    /usr/include
    /usr/include/linux
    /usr/local/include
etc. 

I tried `std::cout` and `using namespace std;` `cout` but it still says unresolved. 

I have imported `iostream` and `cstdlib`.

Also, I&#39;m on Ubuntu 12.04 with eclipse 3.7.2.

Code snippet:

    #include &lt;cstdio&gt;
    #include &lt;cstdlib&gt;
    #include &lt;cstring&gt;
    #include &lt;iostream&gt;
    #include &quot;XPLMDisplay.h&quot;
    #include &quot;XPLMGraphics.h&quot;

    int XPluginStart(char * outName,  char * outSig,  char * outDesc) {
        /* ... */
        std::cout &lt;&lt; &quot;test&quot; &lt;&lt; std::endl;
        /* ... */
    }

using namespace std;

UPDATE: I had created the eclipse project from existing code. Creating a new c++ project fixes it. I&#39;ll accept an answer that explains what setting in the existing project could cause this (so I don&#39;t have to cut &amp; paste all my projects).

Eclipse CDT: Symbol &#39;cout&#39; could not be resolved

I am running Eclipse Helios and I have g++-4.6 installed. Hope I am not wrong that g++4.6 implements C++ 11 features. I have created a C++ project which uses the nullptr and auto keywords. The build gives the following errors:-

    ../{filename}.cpp:13:13: error: ‘nullptr’ was not declared in this scope
    
    ../{filename}.cpp:14:2: warning: ‘auto’ will change meaning in C++0x; please remove it [-Wc++0x-compat]

Actually it was building fine until yesterday. I am getting these from nowhere today. Please help me solve this problem.

I have a custom builder in CDT, which adds alot of files into project directory. I want those files to be filtered out from Project Explorer, but cannot figure out how (the file mask is *.ooj).

Is it possible to add a custom filter by file mask into Customize View? Or maybe there is anther way to hide files in Project Explorer?

Eclipse: how to hide custom files in Project Explorer

When I use eclipse and see my name in the javadocs as the author, I also find the spellchecker marking my name as it does not understand that it is a proper name. Thus, I get the option of:

`Add {word} to dictionary`

but when I click on it, It says the user dictionary is missing and asks if I would like to create a new one. When I say yes, it just shows the spell checking preferences with a blank user dictionary field where I have the option to only add an existing user dictionary and no option to create a new one.

How do I create the user dictionary so that I can configure it for use in eclipse?

How to see my Eclipse version?

I&#39;ve had Eclipse for Java on my computer for a few years, and decided to install the CDT and learn C. I installed both `MinGW` and `Cygwin` and the CDT detects and tries to use them when I make a new project. 

I choose `File &gt; New C++ Project` and choose `Hello World C++ Project` and the `CygwinGCC` toolchain. I name the project &quot;asdf&quot; and hit &quot;Build Debug&quot; in the toolbar. The compiler completes without error. I hit Run and nothing happens. 

Browsing to the project directory manually and running asdf.exe gives me an error saying:  
**`&quot;The program can&#39;t start because cygwin1.dll is missing from your computer. Try reinstalling the program to fix this problem.&quot;`**  

The same thing happens using MinGW, only a different dll is missing.  
**What do I need to do to have a usable .exe?**  
(I&#39;m running Windows 7 x64 and the newest version of Eclipse and the CDT.)

EDIT:
The compiler output is as follows:

    **** Build of configuration Debug for project asdf ****
    
    make all

Is there any plugin in `Eclipse` that auto generates `interface` based on solid class/impl concrete `class`?
