I am new to Eclipse CDT. I did some online search but I got lost. I installed MinGW (works fine with command window), then I installed Eclipse Helios wascana. I did add path/enviroment to Properties->C/C++ build -> enviroment (C:\MinGW\bin)
Eclipse underlines
#include <stdlib.h>
#include
#include
unresolved inclusion. I guess I did not link it to MinGW libraries.
Can anyone help?
In my case, I did the following: Properties->C/C++ Build -> Tool Chain Editor then I chose MinGw GCC as the current toolchain. It looks like it works now. Give it a show
Go to:- properties> C/C++ Build> Tool Chain Editor>
then, select :-
Current Tool chain as --> Cygwin GCC
and,
Current builder as --> CDT Internal Builder
it worked for me. hope it will work for u and others as well!! :)
EDit : for linux users
I got this error even when the compiler was certanly ok, so only build/rebuild (sometimes) and starting new project could help. May be it's not your case, but Eclipse "loves" this error so much, that's wat i found out about it

Alright, hello guys. I've been using Eclipse Luna for some time now while programming in Java. Recently, due to school work, I decided to download the C/C++ for the eclipse as well. I have installed it and all went well. Then I wrote a simple programme and Eclipse will not run it.
Each time there is a pop up: Launch failed. Binary not found.
Also, Eclipse says there is the following error: Program "make"not found in PATH.
Now, I have tried everything to fix it. I'm using the MinGW. I also downloaded Msys.I added all the necesarry paths into the System enviroment variables and done the same thing in the Eclipse.
I went into the Window -- Preferences -- C/C++ -- New C/C++ project and under Binary Parsers selected the PE Windows Parser. I've tried other things as well, like adding the following line into the eclipse.ini as someone suggested:
-DMINGW_HOME=C:\Program Files (x86)\CodeBlocks\MinGW
Nothing seems to be working though and I sadly cannot run even the simplest of programs. Haalp, please.
Kind regards,
George.
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 just installed Dev C++ and I am learning C programming.
the code i used was
#include <stdio.h>
int main()
{
printf("Hello world");
getch();
}
I saved it as a .c file. When I compile it works fine, but when I compile and run it says source file not compiled. So I googled buncha things and came across this video on youtube which shows you how to fix it. I also saw other forums on google which suggest the same thing... However, after doing whats asked, Now I can't even compile my code. I get this error
Compiler: Default compiler
Executing C:\Dev-Cpp\bin\gcc.exe...
C:\Dev-Cpp\bin\gcc.exe "C:\Users\ubaid\Documents\C\Untitled1.c" -o "C:\Users\ubaid\Documents\C\Untitled1.exe" -I"C:\Dev-Cpp\include" -L"C:\Dev-Cpp\lib"
gcc.exe: Internal error: Aborted (program collect2)
Please submit a full bug report.
See <URL:http://www.mingw.org/bugs.shtml> for instructions.
Execution terminated
I have also used what is asked on this link, and still no luck..

I am using windows 8
I was having this issue and fixed it by going to:
C:\Dev-Cpp\libexec\gcc\mingw32\3.4.2
, then deleting collect2.exe
Install new version of Dev c++. It works fine in Windows 8. It also supports 64 bit version.
Download link is http://sourceforge.net/projects/orwelldevcpp/ .
I guess you're using windows 7 with the Orwell Dev CPP
This version of Dev CPP is good for windows 8 only. However on Windows 7 you need the older version of it which is devcpp-4.9.9.2_setup.exe
Download it from the link and use it.
(Don't forget to uninstall any other version already installed on your pc)
Also note that the older version does not work with windows 8.
This maybe because the c compiler is designed to work in linux.I had this problem too and to fix it go to tools and select compiler options.In the box click on programs
Now you will see a tab with gcc and make and the respective path to it.Edit the gcc and make path to use mingw32-c++.exe and mingw32-make.exe respectively.Now it will work.
The reason was that you were using compilers built for linux.
You can always try doing it manually from the command prompt. Navigate to the path of the file and type:
gcc filename.c -o filename
I found a solution. Please follow the following steps:
Right Click the My comp. Icon
Click Advanced Setting.
CLick Environment Variable. On the top part of Environment Variable Click New
Set Variable name as: PATH then
Set Variable Value as: (" the location of g++ .exe" )
For ex. C:\Program Files (x86)\Dev-Cpp\MinGW64\bin
Click OK
This error occurred because your settings are not correct.
For example I receive
cannot open output file Project1.exe: Permission denied
collect2.exe: error: ld returned 1 exit status
mingw32-make.exe: *** [Project1.exe] Error 1
Because I have no permission to write on my exe file.
After some investigation, and with Dr.Topaz's help, I have learned that you will want to confirm that the program set for g++ in the Compiler Options really does compile the source code. In my case, the C:\Dev-Cpp\bin\g++.exe program did not create an exe, but the C:\Dev-Cpp\bin\c++.exe program did. Either program appears to be intended to take the same arguments and options as GNU g++. I would love to find an actual doc on the Dev-C++ compiler programs, but I have not so far.
You can test the compiler program with a simple example like this:
C:\Dev-Cpp\bin\c++.exe hello.cpp -o hello.exe
Currently in 2021, the Dev-C++ site invites you to download either original Dev-C++ or a newer fork by a group named Embarcadero.
I decided to try the Embarcadero version and the experience was slightly better. The UI is still a tad dated, but the g++.exe program it came with was able to compile programs without issue. Again, take note of where the program is being installed, but in my case, the Embarcadero compiler programs were in C:\Program Files (x86)\Embarcadero\Dev-Cpp\TDM-GCC-64\bin.
Both original Dev-C++ and Embarcadero come with mingw-32 versions of the compiler programs that from what I see do work in a Git Bash console, with slight differences such as not recognizing a default locale when using the command std::cout.imbue(std::locale("")).
I faced this similar error, and none of the solutions worked.
so I tried to download the latest version from here, https://www.bloodshed.net/
I rerun the program.
and everything is now working correctly.
I was facing the same issue as described above.
It can be resolved by creating a new project and creating a new file in that project.
Save the file and then try to build and run.
Hope that helps. :)
I am using Eclipse for a C project. I created a new Project by going to New->C project->Executable->Empty Project, Linux gcc toolchain.
When I add a new .c file, I get "program 'g++' not found in path".
How do I get rid of this? I'm not even using C++.
I had similar problem and it is solved by
Installing g++ The GNU C++ complier using ubuntu software centre and
Changing in -
Window -> Preferences -> C/C++ -> Build -> Settings -> Discovery -> CDT GCC Build in Complier Settings [Shared]
From: ${COMMAND} -E -P -v -dD "${INPUTS}"
To : /usr/bin/${COMMAND} -E -P -v -dD "${INPUTS}"
I hope it helps.
For posterity I'm going to post my own solution to this problem. None of the answers above or on related StackOverflow questions helped; most referred to menu entries that didn't exist, and the ones I could try did nothing. I searched other sites as well; there were about 6 different answers repeated many times, and none helped.
Short answer: I blew away the Eclipse install and replaced it. Then it worked. For me at least it wasn't a project or configuration option (at least not one I could get to from the GUI); something in the Eclipse program folder had gotten tweaked and only a new install could repair the problem.
I'm doing Android development using the "ADT" (Android Developer Tools) build of Eclipse. I did something to the configuration that made it start giving the above error (actually two errors, for gcc and g++ both). And I tried plenty of potential solutions (in addition to my own searching for options that might help) with no success.
Thing is, I didn't NEED gcc or g++ in the path. I'm doing Android development, and while both are used in the build process, I'm not using Eclipse to do the builds; I use the Android build system. And the C/C++ Build/Discovery options didn't even give me an option for setting paths for gcc or g++. Other answers I found elsewhere referenced menu entries that don't exist, and most seemed to be about helping people to use the normal C/C++ build within Eclipse, which I didn't need to do.
So I used this opportunity to download the latest ADT package from Google, and then I ran the new one, importing the existing project into a new workspace (just in case the old workspace was corrupted or otherwise part of the problem). No more annoying gcc/g++ error.
I got the same error while I was using "Eclipse IDE for C/C++ Developers."
Install Eclipse from Ubuntu Software Center and then download and install Eclipse CDT.
To install CDT, open Eclipse -> Help -> Install New Software -> Add -> Archieve...
Then give CDT path to there. That's all
I was able to fix the problem by selecting
project(right click in Project Explorer on your project)->properties->Tool Chain Editor
and switching the Current Toolchain: to Android GCC and Current Buolder: to Android Builder
I also had the same problem. I did not have this error running my program but after a adding, including different Api and paths , probably unintentionally some changes happened in my Path that I could not fix it.
I could fix this error by going to Properties and just restore default for all the Tabs.
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.
