I cannot seem to figure out how to use Eclipse CDT.
I am on Mac OS X, and am trying to print "Hello World" in C but I get an error:
Program "gcc" not found in PATH.
What can I do to use C in Eclipse?
I had the same problem. It may be because you don't have GCC compiler installed on your computer.
On OSX, you just have to open the Terminal and check which gcc. If it doesn't return a path, then install GCC from here.
Once installed, this command should return the path :
I just had to restart Eclipse and everything worked well then.
Have you installed XCode on your machine
update
I would suggest following this tutorial to install brew. You can skip the ruby part if you don't need it.
This is how i got rid of it.
Install the MinGW.
Select all files in the Basic Setup and select apply the changes.
Select new C++ Project You will be able to see "MinGW GCC" in the toolchain section select the same and create project.

I get the following error :
Error:Neither MinGW nor Cygwin is selected
Do you have idea for resolve this issue?
To elaborate on the answer provided by "uta" you need either MinGW or Cygwin in order to compile your code. MinGW can be obtained from here: MinGW
Or Cygwin from here:
Cygwin
For simplicity I will describe MinGW. Install MinGW then navigate like so in CLion:
File -> Settings -> Build, Execution, Deployment -> Toolchains
And select the directory you have MinGW installed. I believe by default on Windows it's C:\MinGW. Once you've done this CLion will scan the directory and detect it.
If you already have them installed then you need only select the folders they're installed in in CLion.
Hope this helps.
Please, start from menu:
File | Settings... | Build, Execution,... | Toolchains | Environment:
Please note: Although I'm specifically talking about the Eclipse CDT plugin, I'm almost 100% confident that any Windows/C/MinGW programmer can answer this question.
I'm on Windows 7 and am trying to write and compile a simple "Hello, C!" C application using Eclipse's CDT plugin. I'm reading their docs which state that having GCC installed is a prerequisite.
I just installed MinGW, making sure to include the following packages:
mingw-developer-toolkit
mingw32-base
mingw32-gcc-g++
msys-base
Back in the CDT docs (under the section titled Windows configuration), it states that I need to add g++, make and GDB to my PATH.
I'm wondering where MinGW installs these utilities, so that I can add them to my system PATH, and make the Eclipse CDT recognize their location at startup.
When using the Eclipse CDT plugin, you need GCC and its 3 specific utilities installed locally. These three utilities are: g++, make and gdb.
On Windows you can choose to install these utilities via Cygwin or MinGW. For a MinGW-based solution, go to their site and download the MinGW Package Manager. Then open the manager and install the following packages:
mingw-developer-toolkit
mingw32-base
mingw32-gcc-g++
msys-base
Then go to File >> Apply Updates and apply them. This will install the 3 utilities to the following directories on your machine:
C:\MinGW\bin\g++
C:\MinGW\bin\gdb
C:\MinGW\msys\1.0\make
Add these 3 binaries to your system PATH, restart Eclipse and you are all set.
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 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.
How do I compile a .c file on my Mac?
You'll need to get a compiler. The easiest way is probably to install XCode development environment from the CDs/DVDs you got with your Mac, which will give you gcc.
Then you should be able compile it like
gcc -o mybinaryfile mysourcefile.c
You will need to install the Apple Developer Tools. Once you have done that, the easiest thing is to either use the Xcode IDE or use gcc, or nowadays better cc (the clang LLVM compiler), from the command line.
According to Apple's site, the latest version of Xcode (3.2.1) only runs on Snow Leopard (10.6) so if you have an earlier version of OS X you will need to use an older version of Xcode. Your Mac should have come with a Developer Tools DVD which will contain a version that should run on your system. Also, the Apple Developer Tools site still has older versions available for download. Xcode 3.1.4 should run on Leopard (10.5).
In 2017, this will do it:
cc myfile.c
Just for the record in modern times,
for 2017 !
1 - Just have updated Xcode on your machine as you normally do
2 - Open terminal and
$ xcode-select --install
it will perform a short install of a minute or two.
3 - Launch Xcode. "New" "Project" ... you have to choose "Command line tool"
Note - confusingly this is under the "macOS" tab.
Select "C" language on the next screen...
4- You'll be asked to save the project somewhere on your desktop. The name you give the project here is just the name of the folder that will hold the project. It does not have any importance in the actual software.
5 - You're golden! You can now enjoy c with Mac and Xcode.
You can use gcc, in Terminal, by doing gcc -c tat.c -o tst
however, it doesn't come installed by default. You have to install the XCode package from tour install disc or download from http://developer.apple.com
Here is where to download past developer tools from, which includes XCode 3.1, 3.0, 2.5 ...
http://connect.apple.com/cgi-bin/WebObjects/MemberSite.woa/wo/5.1.17.2.1.3.3.1.0.1.1.0.3.3.3.3.1
Ondrasej is the "most right" here, IMO.
There are also gui-er ways to do it, without resorting to Xcode. I like TryC.
Mac OS X includes Developer Tools, a developing environment for making
Macintosh applications. However, if someone wants to study programming
using C, Xcode is too big and too complicated for beginners, to write
a small sample program. TryC is very suitable for beginners.
You don't need to launch a huge Xcode application, or type unfamiliar
commands in Terminal. Using TryC, you can write, compile and run a C,
C++ and Ruby program just like TextEdit. It's only available to
compile one source code file but it's enough for trying sample
programs.
Use the gcc compiler. This assumes that you have the developer tools installed.
STEP 1
Just check wheater your MacBook has the compiler or not using this command 👉🏻 clang --version in your command line interface. If the tool exists then you will be able to see the version like this
STEP 2
Next, go to the directory where your source code exists using CMD Interface, then run the command make "filename" without the .c extension.
STEP 3
The final command to run your source code after compiling it is ./filename without the .c extension.
This is how you can compile and run your program on the Macintosh system.
