I installed CodeLite and was rightfully put in the direction to install MinGW. I installed MinGW right from where CodeLite suggests/links to it and everything went well there. I then click "scan" on CodeLite to find the just installed compiler and it says it can't find any on the system -- lost already here.
I then just tried to configure the directory of the compiler to one which is provided with MinGW, such as gcc. I try to compile any basic hello world or such and get the error that, "The system cannot find the file path specified." When trying by default it would compile even before actually properly setting up the compiler, so it seems completely backwards on the face of it. Maybe it's some cross/directory issue?
The log shows CMD.exe looking to cd to some weird/incorrect directory. I've changed environment variables to only include MinGW's path and the issue persists. I've changed around global settings/include paths/build settings to point to the compiler, but it just won't get past this.
Aside from manual setup not working and CodeLite being unable to find MinGW despite it being 100% verified and installed properly, I am basically lost here.
I have prior programming experience, but usually with everything out of the box. I'm now trying to get back in but wanted to learn the process of setting up a compiler/getting more "hands on."
I'm pretty sure it's something set up wrong by me, but the problem is clearly that I have no idea what.
CodeLite does not need the compiler to be in the path. You can "tell" CodeLite where it is installed by pointing it to the right folder from Settings->Build Settings
See this wiki page, note that the build settings dialog is a bit outdated, the drop down button does not exist anymore, instead you have a toolbar with green + button, click it instead.
Once you added the compiler, right click on your project and and select Project Settings, under the General tab, choose the compiler you just configured.
I had the same issue where I had MinGW installed and working, then I downloaded CodeLite and went into the setup wizard, where it could not find MinGW.
Essentially the fix I found was closing and re-opening CodeLite.
I saw on the CodeLite site that the compiler should not be in a folder path with spaces in it, so I moved my compiler from "Program Files" to "ProgramFiles" and manually pointed to it using Settings -> Build Settings. However, CodeLite's scan still couldn't find it until I restarted it.
Then I moved my compiler back to its original folder and restarted CodeLite again, it worked.
I'm having issues with setting up Eclipse for C++ editing. I am using Cygwin and Eclipse (obviously), and I've gotten to the point of making the example project Hello World. However, when I try to create a new project I always get the message "Launch Failed. Binary Not Found". I know this is a common issue, but why would the default hello world project work and not mine?
Thanks for any help.
First Build the project ( project menu in navigation bar)
then, A new folder named Binaries will appear now in project explorer. (refresh if needed)
Now you can try running your project, and no errors will appear.

Hi This is my first time working with C++ on eclipse. I'm using cygwin.
I'm just trying to create a simple hello world program. The build is successful but when I try to run, it says "launch failed. binary not found".
In settings which I check the run configuration, there's nothing listed on clicking "search project..". Am I doing something wrong?
Would really appreciate any help on this. Thanks!
You probably found your solution, but here's for anyone else who might have the same problem:
If you want to use cygwin toolchain then you'll have to build a makefile first, and then build your project. You can follow the official guide here: http://help.eclipse.org/indigo/index.jsp (C/C++ Development User Guide >> Getting Started >> Creating a Makefile project)
If you don't mind changing the cygwin toolchain: The fastest way to build and run a C/C++ project would be to create another project, this time un-ticking the show project types and choose as MINGW GCC toolchain (check 1st image below). After you create your project, you just right click on project and choose the rebuild option (check 2nd image below).
When programming in eclipse (c++), I would like to just hit f5 (run) and have the project I'm working on save, build and (if there are no errors) run. If there are errors I want it to show the problems window and stop.
This all works at the moment except for the part where it shouldn't run when there are errors.
Is there a way to make eclipse never run the project when there are errors? Perhaps with an addon?
EDIT: Forgot to mention the prompt... The prompt does show but I want it to not show at all. If you look at the preference window you'll see that there's no 'never' option, there is one for all the other options but not for the 'launch if project contains errors'.
By default, Eclipse CDT does not run code with build errors, but maybe you have checked the option Always launch without asking checkbox.
You should go to Windows menu->Preferences->Run/Debug->Launching->Continue launch if project contains errors and check Prompt option instead of Always. Using this, Eclipse CDT will prompt you if errors exists during building or launch your binary if it has been compiled without errors.
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)
