After a war against Eclipse and MinGW, I managed to build a hello world program in Eclipse but now I am getting an annoying error. Sometimes when I try to build something I get:
cannot open output file *.exe: Permission denied
I have seen some answers around about this issue but none solved the problem. So here is some aditional info.
1) Usually, the first build works.
2) There is no process stuck in the task manager (as some suggessted).
3) I am using Windows 8 and MinGw.
4) No binary folder nor executable is created.
5) This problem happens chronologically.
Changed from MinGW to Cygwin and it worked.

I'm setting up the Netbeans IDE, and i downloaded Cygwin for the compiler, make and debugger (Windows 8.1). The problem is that when i try to debug or run, this error happens.
C:\\cygwin64\\bin\\bash: exec /cygdrive/C/Users/MyName/Documents/NetBeansProjects/Pi_1/dist/Serial/Cygwin-Windows/pi_1.exe: No such file or directory
RUN FAILED (exit value 127, total time: 90ms)
I don't know if i'm missing something to install or if i used wrong versions of g++, make, etc...
I had experienced a similar problem on other IDEs (haven't used Netbeans). It turned that the anti-virus was quarantining the executable generated after compilation. I just "whitelisted" (prevent anti-virus from scanning in future) the directory where i saved my programs, and that solved the problem.
I had such error. In my case the folder name in the project path was the reason. Try to change location of your project to something simple, like "c:\NetBeansProjects\prj1".
Happened to me as well. The reason, as already mentioned, was that the build folder contained characters as () and spaces.
C / Windows 10
Just to add, I had the same problem when saving my projects in a different folder than the predefined one. Example: C:\Users\username\Desktop\C_Programs\new12. This was fixed using the predefined project folder: C:\Users\username\Documents\ NetBeansProjects\new12.(Windows 10)
I'm trying to learn C++ using NetBeans but even though I have CYGWIN and everything set up in my PATH, I keep getting an error that says: "No shell found. Cannot proceed. Please install either CYGWIN or Msys."
I don't know what Msys is but since the error says "or" I assume that if I have CYGWIN that I don't need to have Msys.
I'm trying to run the basic "Hello World!" tutorial but this error from what I've seen isn't covered. I'm getting aggravated because I have a project I need to have done in a few weeks.
If anyone has any answers for me, that would be great. I can supply screenshots if you need them.
Cygwin alone is not enough, first of all you have to check if you installed C++/gcc/gdb packages in your Cygwin.
From Cygwin/Net beans docs:
Open the Control Panel (Start > Settings > Control Panel) and double-click the System program.
Select the Advanced tab and click Environment Variables.
In the System Variables panel of the Environment Variables dialog, select the Path variable and click Edit.
Add the path to the cygwin-directory\bin directory to the Path variable, and click OK. By default, cygwin-directory is C:\cygwin. Directory names must be separated with a semicolon.
Click OK in the Environment Variables dialog and the System Properties dialog.
If it fails you could try to Re-Install Netbeans from/within an cygwin/bash instance start the netbeans from a cygwin/bash instance.
Netbeans should automatically detect gdb/g++
PS: I'd prefer to use a good Gnu/Linux distro
I had the same problem with 8.1.
Adjusting the %PATH%-variable - in my case adding C:\msys64\usr\bin - solved it (as wdavilaneto's slightly verbose answer suggested).
This is not an answer but it adds to this question, I know that isn't very objective but in this case there may be a problem with Netbeans. I have 7.3 so this could be the reason. I am getting the same error but it used to work just fine, then one day it just stopped working and couldn't find the Shell. I have everything you need to make C/C++ work for Netbeans and it was working, for a while too!
It is rather old, but I've had the same issue a moment ago. It "Solved itself" by Creating a new "welcome sample" project and then made it run, then went back to my original project and made it run again. For me, it solved the problem. Probably it is related to an issue with Netbeans as Cian said.
Btw, I'm with Netbeans 8.1.
Make sure the shell is in your path! Depending whether you have Cygwin, Mingw32, Mingw32, TDM Mingw... it will be somewhere here:
c:\<installation path>\usr/bin
Hmh, I have 2 C compilers one for 64bit and one for 32bit set in NetBeans. When I had 32bit compiler without 64bit one then compiling went fine but when I have installed 64bit then NetBeans has started to do some problems, firstly everything went fine but then I started to get this problem to. For me fix is to switch from 64bit compiler back to 32bit compiler, then compile my program and then go back to 64bit compiler and now I can compile it with 64bit compile... Not sure why is this fixing it.
I have this problem with Netbeans 10.
Computer is Windows 10 x64.
Resolved by following the answer given by TNT.
Problem was when start building my project the said "no shell" (the topic of this posting) dialog box popped up. Since there was no command prompt, the build tools cannot run - process cannot spawn.
Solution was to give the correct path (environment variable). Since I am using MSYS, Since I am using MSYS, adding
F:\msys64\usr\bin
to my PATH made it work.
Running or debugging anything gives me an extremely frustrating "Launch failed. Binary not found" error. I'm using Eclipse with a CDT plugin installed (specifically, I have the MinGW package installed).
I already tried setting both the user and system PATH variables to include my (MinGW directory)/bin
I also tried building the program before running it.
I also made sure that PE Windows Parser under the project's settings was enabled.
I went to Project Properties > Run/Debug Settings > New > C/C++ Application > Environment > Select > and I selected the Path
I also tried setting the C/C++ Application in the Main tab to the executable file that is made from building the program, but no such file is made when I do build my program. I seriously doubt that this is what's causing the problem, though.
I'm running out of options, and the problem still persists. What else needs to be done? What am I doing wrong?
When I was looking through the install instructions for MinGW, the tutorial referenced the mingw base package as the package to install after installing MinGW. But mingw base was not available to me. Instead, I saw mingw32 base. Could it be that Eclipse, a 64 bit program, is trying to run 32 bit code? Is that what's going on? If that's the problem, how do I fix it?
Build
Refresh the project. A new folder named Binaries will appear now in project explorer.
Now Run :)
It took me 3 days to figure out my problem. My Hello World C program would compile in eclipse using the Windows PE Parser, but there was NO EXE FILE!!!! AVAST Antivirus was identifying the exe file as a false positive and removing it....grrrrr. The solution was to add the eclipse workspace folder to the exclusions list. Voila!! Eclipse generated my test.exe file.
save the file first before you build and run... it works with me
Check the compiler you set while you created the project . If that is MINGW or Visual Studio ; check whether they are downloaded or not . If not do so and start a new project by closing the old one . Build the new project by pressing Ctrl + B and a new file 'Binaries' is created in the package explorer . Now you can use the run option to run the project .
First the solution: install "make"
I had the same issue.
I also tried the steps you did with no luck.
After some time i found a the solution!
The problem was that i did not have the application "make".
Apparently its not installed by default on Cygwin and eclipse doesn't give any indication for that...
I have installed cygwin in order to compile C++ source code. At this stage I can run the C++ app by invoking it directly via icon. But once I type g++ on the cmd command line I receive 'Access denied' message. That command works fine on cygwin terminal window. How to deal with this issue? This questions has been trig-erred by the another issue which is present on this forum.
It is that I cannot see the output on Eclipse IDE once I run the C++ app (no errors). I though t the thing that I receive that 'Access denied' message on cmd might be the culprit for the mentioned trouble. Just trying out all the things.
Best regards
Did you add cygwin to your path in windows?
I'm not familiar to cygwin, but theres a code you can try. It is similar to "sudo" on linux, and it gives you more privileges...
It's called "runas". Take a look on this site: http://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/runas.mspx?mfr=true
I'm using Eclipse Helios on Ubuntu 10.04, and I'm trying to install CDT plugin on it. I download it from here here.
And then I go to Install New Software and select the zip file (I don'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.
You must build an executable file before you can run it. So if you don't “BUILD” your file, then it will not be able to link and load that object file, and hence it does not have the required binary numbers to execute.
So basically right click on the Project -> Build Project -> Run As Local C/C++ Application should do the trick
First you need to make sure that the project has been built. You can build a project with the hammer icon in the toolbar. You can choose to build either a Debug or Release version. If you cannot build the project then the problem is that you either don't have a compiler installed or that the IDE does not find the compiler.
To see if you have a compiler installed in a Mac you can run the following command from the command line:
g++ --version
If you have it already installed (it gets installed when you install the XCode tools) you can see its location running:
which g++
If you were able to build the project but you still get the "binary not found" message then the issue might be that a default launch configuration is not being created for the project. In that case do this:
Right click project > Run As > Run Configurations... >
Then create a new configuration under the "C/C++ Application" section > Enter the full path to the executable file (the file that was created in the build step and that will exist in either the Debug or Release folder). Your launch configuration should look like this:
Go to the Run->Run Configuration-> now
Under C/C++ Application you will see the name of your executable + Debug (if not, click over C/C++ Application a couple of times). Select the name (in this case projectTitle+Debug).
Under this in main Tab -> C/C++ application -> Search your project -> in binaries select your binary titled by your project....
You must "build" before "run", otherwise "Binary not found". You can set up "Auto build", so that it will build and run. Check this post to set up "Auto build" http://situee.blogspot.com/2012/08/how-to-set-eclipse-cdt-auto-build.html
I had this problem for a long while and I couldn't figure out the answer. I had added all the paths, built everything and pretty much followed what everyone on here had suggested, but no luck.
Finally I read the comments and saw that there were some compilation errors that were aborting the procedure before the binaries and exe file was generated.
Bottom line: Do a code review and make sure that there are no errors in your code because sometimes eclipse will not always catch everything.
If you can run a basic hello world but not your code then obviously something is wrong with your code. I learned the hard way.
If you still have an error even after building the project then try to do this:
click on Binaries in Project Explorer with the left button
click on green "Play" button (Run Debug)
I was having this same problem and found the solution in the anwser to another question:
https://stackoverflow.com/a/1951132/425749
Basically, installing CDT does not install a compiler, and Eclipse's error messages are not explicit about this.
I faced the same problem. I have Eclipse Indigo and Eclipse Luna on Ubuntu. I tried many solutions, but none worked. Here's how you can try :)
Try it in order :)
Either do Build All and then compile :)
Install G++ Compiler
Windows->Preferences->NEW CDT PRoject-> Makefile-> Binary Parsers-> Choose Cywin or Window PE depending on your Os :)
Change your toolchain to cywin gcc
Project->Properties->Environment-> Release Active
After 1,2, 3, and 4, I tried changing paths, and other stuff, but nothing worked. In the end, I noticed that it mentioned Debug Active was not configured. So when I changed it to Release Active, it worked. Do note that change in environment and path is not required.
I faced the same problem while installing Eclipse for c/c++ applications .I downloaded Mingw GCC ,put its bin folder in your path ,used it in toolchains while making new C++ project in Eclipse and build which solved my problem.

Seems like having "Build Automatically" under the Project menu ought to take care of all of this. It does for Java.
make sure you have GDB installed on your system...
If your using Linux based OS simply in a terminal type:
sudo apt-get install gdt
when finished downloading extract the file and install.
close your IDE (in this case eclipse and open it again and run your project.
Adding the compiler to the PATH fixed the problem for me...
export PATH="$HOME/opt/cross/bin:$PATH"
My problem was the same as one commenter above. I had to change the binary parser to the correct one (PE for windows, ELF for Linux, mach for mac)
