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.

Everytime I try to build and run a program, including the standard 'Hello world!' nothing happens, I get:
==== Program exited with exit code: 0 ====
Time elapsed: 000:00.000 (MM:SS.MS)
Press any key to continue...
At the bottom it says:
'ming32-make' is not recognized as an internal or external command, operable prgram or batch file.
I have Codelite version 16 on Windows 10. I also have MinGW installed to C: and have edited the Environment variables to include C:\MinGW\bin
However, in command prompt gcc --version shows me the gcc version in C:\Users\me> and not C:\MinGW
I don't know if this is relevant or not.
All the other results seem to suggest a compiler not found problem, but this does not seem to be my case. Thanks in advance.
This is what I have installed at the moment. Can I get 'make'from one of the other files?
The Installed files
Looks like you either don't have ming32-make.exe or it can't be found.
Also I notice you still use old MinGW. I would recommend switching to newer MinGW-w64 (which supports both Windows 32-bit and 64-bit).
The standalone build from https://winlibs.com/ does include ming32-make.exe, and since you can just unzip it (no installation needed) you can try it without removing the old MinGW. Just make sure you don't have anything in your PATH variable to avoid running programs from the wrong location.
ming32-make.exe is either not installed or can't be found on your Environment variable PATH.
No, there is no mingw32-make in that bin folder. When I used the Installer originally I only selected: mingw32-gcc-g++-bin although there were other bin files. Where can I get it?
mingw32-make is outdated.
See How to compile makefile using MinGW?
If you are having problems with mingw, I would recommend using MSYS2 or a package manager like Chocolatey.
Just get rid of the previous installation first. Not mandatory but prevents confusion and storage drain due to multiple copies of mingw.
To install MinGw using chocolatey, run cmd as admin and use
choco install mingw
For make
choco install make
What worked for me was also installing mingw32-base-bin from the Installer (see second option in image in the original question).
The installation tutorial I was following did not mention installing this.
I've decided to leave this here as an answer in case someone else runs into a similar problem.
MSYS is a good option for compilers in recent CodeLite or VS-Code installation. https://www.msys2.org/.
Once you downloaded the compiler using the following steps from the installer but still have the problem with the make then follow these steps:
Reopen the MSYS2 terminal from your windows if that is previously installed.
Run the command pacman -S --needed base-devel mingw-w64-x86_64-toolchain
You will be asked to select the option from the list. You should select the option which refers to mingw-w64-x86_64-make.
Once the installation is successfully done, then open CodeLite settings->Buid Settings and check your Make file location. If that is empty or showing an unknown location then click the three dots at the very right of that box. The browse and navigate to location or where you installed the make by pacman. In my case it is C:/msys64/usr/bin/make.exe.
Click Apply and Save.
Now it might be needed to create a fresh workspace and re-run your code.
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'm trying to compile a downloaded program in Windows. The program is usually run in Linux, but is programmed to also run in Windows (the code has #if defined(_WIN32)'s in it, and claims to work with borland free tools). When I try to use make from the command line, it tells me "Incorrect command line argument: -C". In the makefile, there are many lines that say "make -C" followed by a directory name. Does this syntax not work in Windows? What is a correct way to do this? Is there any way to compile this for native use in Windows with this makefile?
Windows itself doesn't come with a make utility. Microsoft does have a 'make' utility that comes with their development tools (such as Visual Studio, the Platform SDK, or the Windows Driver Kit) but it's called nmake.
You probably need GNU make to process those makefiles. you can get a copy for Windows here:
http://unxutils.sourceforge.net/
However, if the makefile isn't written to be able to be run on Windows, it'll probably not work well. You'll also need to make sure you have whatever other development tools the makefile calls upon (maybe the Borland compiler or GCC), and there may be other configuration that needs to be done specific to the project you want to build. It's probably not a matter of just having the correct make utility.
-C is "change working directory" only for the gmake command (from the GNU package). You should take a look in the manual for your Make-Utility and see, wheather it supports something äquivalent.

Are you using cygwin?
Are there any instructions for installing on windows(perhaphs in a README file)?
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.
I haven't done C in a long time. I'd like to compile this program, but I have no idea how to proceed. It seems like the makefile refers to GCC a lot and I've never used GCC.
I just want an executable that will run on windows.
You may need to install either cygwin or mingw, which are UNIX-like environments for Windows.
http://www.mingw.org/
http://www.cygwin.com/
When downloading/installing either cygwin or mingw, you will have the option of downloading and installing some optional features; you will need the following:
gcc (try version 2.x first, not 3.x)
binutils
GNU make (or gmake)
If it requires gcc and you want it to run on Windows, you could download Cygwin.
That's basically an emulator for GNU/Linux type stuff for Windows. It works with an emulation DLL.
http://www.cygwin.com/
In order to compile this program you need a C compiler. It does not have to be gcc, although you are already given a makefile set up to use gcc. The simplest thing for you to do would be the following:
Install cygwin
Open the cygwin command prompt
go into the directory where you have your makefile
type 'make'
That should compile your program
If you are not comfortable with using command line tools then you can download the free version of MS Visual Studio and import the source files into a new Visual Studio project. This way you would not need to install cygwin and use gcc, but you would need to know how to create projects and run programs in Visual Studio.
You almost certainly don't need all of cygwin to compile using gcc. There are plenty of standalone gcc clones for Windows, like gcw.
If it's reasonably portable C code (I haven't looked at it), then you may be able to just ignore the included Makefile and feed the source into whatever compiler you do want to use. What happens when you try that?
Dev-C++ provides a simple but nice IDE which uses the Mingw gcc compiler and provides Makefile support. Here are the steps I used to build the above code using Dev-C++ (i.e. this is a "how-to")
After downloading the source zip from NIST, I
downloaded and installed the Dev-C++ 5 beta 9 release
created a new empty project
added all the .c files from sts-2.0\src
Then under Project Options
added -lm in the Linker column under Parameters
added sts-2.0\include to the Include Directories in Directories
set the Executable and Object directories to the obj directory under the Build Options
and then hit OK to close the dialog. Go to Execute > Compile and let it whirl. A minute later, you can find the executable in the sts-2.0\obj directory.
First, there is little chance that a program with only makefiles will build with visual studio, if only because visual studio is not a good C compiler from a standard POV (the math functions in particular are very poorly supported on MS compilers). It may be possible, but it won't be easy, specially if you are not familiar with C. You should really stick to the makefiles instead of trying to import the code in your own IDE - this kind of scienfitic code is clearly meant to be compiled from the command line. It is a test suite, so trying things randomly is NOT a good idea.
You should use mingw + msys to install it: mingw will give you the compilers (gcc, etc...) and msys the shell for the make file to run correctly. Contrary to one other poster, I would advise you against using gcc 2 - I don't see any point in that. I routinely use gcc 3 (and even 4) on windows to build scientific code, it works well when the code is unix-like (which is the standard platform for this kind of code).
