I've downloaded Eclipse C/C++ IDE . I need to run a simple c program in this(To print welcome).
While trying to run the program its popping up an error message like "Launch failed: Binary not found" .
Need i install any compiler package. ?
Please help me to do this.
Yes, you have to install a compiler, Eclipse is only an IDE. You can get MinGW here.
http://www.eclipse.org/cdt/
Look at the above link,you will get more idea,on how to do development using C/C++ using eclipse.
You can make use of the documentation which comes along with the IDE.
Just on the start up window in Eclipse click Tutorials and then click on c/c++ development link and then read Before you Begin part.
The program you write must be converted into respective binary which is to be run on that particular architecture.This process is carried out by the compiler as a result compiler is required for eclipse IDE to compile and link the code .
Various compilers are available such as Microsoft Visual C++ MinGW GCC or Cygwin GCC in the form of chaintools in eclipse so as to compile the code.
Eclipse is an IDE.It will help you write applications in c/++,but it will not compile your program as Eclipse does not comes with a compiler pre-configured.
You need to install a compiler to run your application.
Eclipse is capable to use many c/c++ compilers,some are:
1.Cygwin
2.MingW
3.Gross
4.Microsoft Visual C++
I would advise to install mingW OR Cygwin.

I am new to programming and not familiar with IDE and developmental tools. I wanted to use Visual Studio Code, so I installed c/c++ extension and code runner offered by VS. But I get 'gcc' is not recognized as an internal or external command,
operable program or batch file.
Some of the similar questions were quite old and I wonder if there are any recent solutions.
I would really appreciate if anyone can send me suggest any tutorials or videos on how to solve this.
Thank you in advance!
Assuming you are using windows;
Most probably there's no compiler installed on your machine. If you want to use VSCode for C programming, you should install a C compliler and add it to path variable in windows.
But my suggestion is use a different IDE, like Visual Studio Commuity or DevC++.
If you want to use VSCode, you should download and install MinGW, Cygwin or any other compiler.
If you are using Mac, Try installing XCode and use VSCode or CodeBlocks.
I am new to C programming.
I was trying to use the pthread API to write some concurrent program.
I downloaded eclipse IDE for C/C++ Developers, MinGW. I have put all the library, header files into the corresponding location of the MinGW file.
When I tried to build the project, there is always an error "cannot find -lpthread", what happened?
I have added the "-pthread" to the GCC compiler.
I have searched a lot in Google but seems no one have similar problem as me.
The answer to this question by someone who is also missing MinGW pthread library should help you out! Essentially the issue is that the MinGW installer script might not download the lpthread library upon installation. Quoted from link:
Just run and open MinGW Installation Manager, which should be pre-installed with MinGW, select "All Packages" on the left panel, and on the right panel, search for "mingw32-pthreads-w32" packages and install them.
I downloaded eclipse IDE for C/C++ Developers, MinGW.
MingGW uses the Windows API. The Windows API does not provide PThreads.
You need to install PThreads for Win32 to have PThreads available under Windows, and with this available under MinGW.
Eclipse is not configured to put the -pthread argument in the gcc compilation. To solve this, go to the Menu:
view sourceprint?
1.Project -> Properties
From the bar on the left:
view sourceprint?
1.c/c++ build -> GCC C Compiler -> Miscellaneous
Add the “-pthread” argument into the beginning of the “Other Flags” Also go to:
view sourceprint?
1.c/c++ build -> Settings -> GCC C Linker -> Libraries
And include the “pthread”library into the other libraries. Click Apply and rebuild the project. Pthreads must work now.
See the question on mingw.org. I ended up with adding 'C:/cygwin/lib' to the settings for the "Library search path (-L)" at properties >> c/c++ build >> settings >> MinGW C Linker >> Libraries.
I am new to C/C++ development in Eclipse and trying to configure Eclipse. I'm working in a Linux environment with GNU GCC and my toolchain is detected by Eclipse. As given in the Eclipse documentation 1, I opened Run>>Run configurations. But the C/C++ Local tab is not there.
This is all I get.
But when I build a sample helloworld program, it's being built correctly.
Any idea why this happens?

I faced same issue as you. I was able to create and build one c/c++ project, but I couldn't run/debug it. Actually, I installed wrong CDT (CDT Visual C++ Support). Next I installed correct CDT (c/c++ development tools) and after one eclipse restart I had c/c++ application inside of Run Configuration.
Can anyone give me step by step tutorial on how to use netbeans to code and compile C code?
Also i have dev cpp but the formating is sick.
GCC is what i use.
Thanks much
netbeans tutorial: http://cnd.netbeans.org/cnd-tutorial.html
In Ubuntu, I do the following:
- Create a new C/C++ project
- Import the sources
- you already have makefiles (or cmake), netbeans you can configure that in the advanced screen.
- You can turn of automatic builds in the same advanced screen
- and build using the normal build command.
I have install the C/C++ CDT Version of Eclipse.
After making a HelloWorld.c file and get the code in there I get an error of "Launch failed. Binary not found".
I found in google that my Eclipse miss the compiler and I install MinGW on my computer and add the path to env variables (tested it with "gcc -v" in cmd and succeded).
But poorly it get the same Launch Failed error - any ideas, what step I forgot?
Some things to check:
1.) MinGW tools are installed as well. Make sure you have the C compiler and the Make program
2.) Check your Environment variables. Make sure both the compiler and Make are on the path.
3.) Eclipse is a temperamental beast at times, don't lose heart :-)
4.) If you're looking for a good IDE (without care for ideological concerns), might be worth looking at Bloodshed C++ IDE and Visual C++ 2010 express (or whatever they call their free version).
5.) Check the options menu in Eclipse to make sure it's looking at the correct environment variables for finding the Path.
IMHO, the simplest setup for eclipse on windows these days is cygwin - it seems to have been updated more recently than mingw, and works better.
Go to http://www.cygwin.com/, download the installer, select the default directory of c:\cygwin. Select 'All users'.
When it offers a list of packages, select 'gcc', 'binutils' and 'make' under the 'devel' category.
Add c:\cygwin\bin to your windows environment PATH.
Make sure Eclipse knows where to find your gcc compiler. An easier way would be to use EasyEclipse until you are more comfortable with your dev env.
I needed to move from the MinGW gcc to the CygWin gcc - all the C++2011 works and others say it is a better option too. Download the CygWin binaries etc. and then open up Eclipse.
In project properties, C/C++ Build -> Environment and set the CYGWIN_HOME variable. This worked fine for me on Eclipse Kepler Windows 7 (64Bit)
I also put the cygwin bin directory at the front of my Windows PATH variable.

You can try installing wascana. It automatically set up GNU compiler for you on Windows.
