I can't get the following code to run:
#include <iostream>
int main()
{
std::cout << "Hello World" << std::endl;
return 0;
}
There are no compile errors.
The build output:

I get the dreaded "Launch failed. Binary not found." dialog. I've been over google for hours now, but nothing works.
In my project folder, a debug or release folder are created (depending on what I set it to) but it's always empty. No 'binaries' folder is created, as some posts mentioned it should.
No proposed solution worked, and disabling the antivirus didn't solve it.
How do I fix this? Thank you.
EDIT
Eclipse Version Kepler Severive Release 1
Build id: 20130919-0819
CDT Version: 8.3.0.201402142303

EDIT2
Changing the "current builder" in properties>c/c++ build>tool chain editor from CDT internal builder to Gnu Make Builder does generate a makefile.

Which compiler are you using? It appears that you are only compiling your code, not linking it too. You must build and link in order for it to work.
The -c flag only compiles the source file. It doesn't link with the object file into an executable. Add this:
g++ -o "..\\Hello.exe" "..\\Hello.o" && "..\\Hello.exe"
Just remove -c flag from your compile line and change -o Hello.o to -o Hello.exe (guess you use Windows).

I'm trying to compile my project in eclipse(linux) for windows.
I followed a guide, then I'm able to compile for windows from command line. I tried to create my project using GCC-toolchain and selecting my prefix/directory
Output on the eclipse console is:
Building file: ../src/provagcc2.cpp
Invoking: Cross G++ Compiler
x86_64-w64-mingw32-g++ -O3 -Wall -c -fmessage-length=0 -MMD -MP -MF"src/provagcc2.d" -MT"src/provagcc2.o" -o "src/provagcc2.o" "../src/provagcc2.cpp"
Finished building: ../src/provagcc2.cpp
Building target: provagcc2
Invoking: Cross G++ Linker
x86_64-w64-mingw32-g++ -o "provagcc2" ./src/provagcc2.o
Finished building target: provagcc2
however, it generates a .o file instead of a .exe
-o "provagcc2" looks like you did not specify an extension for the output. There should also be a provagcc2 without extension lying around somewhere as a result. The provagcc2.o file you have found is likely the is the result of compiling. provagcc2.cpp
-o "provagcc2.exe" is what you want on the command line.
To tell Eclipse to name the file correctly, you need to navigate to Project->Properties on the menu. In the Properties dialog that pops up, expand C/C++ Build and select Settings. Select the Build Artifact tab and type exe into the Artifact extension field. Apply and Close and rebuild the project.
i have a problem with eclipse CDT and cygwin, when i try to build a simple hello world project i have this error:

Cygwin is in the path and commands like 'g++' or 'make' works fine.
Thank in advance for your help.
Follow this tutorial to properly set up cygwin with Eclipse CDI. After completing all the steps, add one more path dependency on: Project Properties -> C/C++ General -> Paths and Symbols -> Includes GNU C++ with the value to : ${CYGWIN_HOME}/usr/i686-pc-cygwin/sys-root/usr/bin. This solved all the issues arising on Eclipse CDT with CYGWIN.
resolution: pass "-static" in miscellanious linker options

I am using Eclipse with the MinGW-w64 Toolchain. My GCC version is 4.8
I want to create a application that consists out of 2 Threads. I've allready tried to implement this into my actually application. Thus it didnt work i decided to make a new test app.
Source(main.cpp):
#include <iostream>
#include <thread>
using namespace std;
void test() {
cout << "works.." << endl;
}
int main() {
thread t(test);
t.join();
return 0;
}

When running i get the following error:
This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.
terminate called after throwing an instance of 'std::system_error'
what(): Operation not permitted
btw: the many -pthread etc. commands come from a couple of trys to make it work.
im running win vista 32 bit
I really appreciate if some one knows how to resolve my problem.
Thanks in advance!

I have installed minGW and msys. In eclipse CDT I created c++ project that uses cross gcc toolchain.
Eclipse created make file which I can use through command line, so if I run make all project is correctly compiled, but if I use eclipse to build, it fails with following message
**** Build of configuration Debug for project cpp ****
make all
Building file: ../src/main.cpp
Invoking: Cross G++ Compiler
g++ -O0 -g3 -Wall -c -fmessage-length=0 -MMD -MP -MF"src/main.d" -MT"src/main.d" -o "src/main.o" "../src/main.cpp"
make: *** [src/main.o] Error 1

I have chosen wrong toolchain in project, changed to mingw gcc and now it works
I just installed cygwin and eclipse on my win7 x64 machine, and after importing my code from svn, I get this weird error:
**** Build of configuration Default for project platform ****
make all
g++ -O2 -g -Wall -fmessage-length=0 -c -o platform.o platform.cpp
process_begin: CreateProcess(C:\cygwin\bin\g++.exe, g++ -O2 -g -Wall -fmessage-length=0 -c -o platform.o platform.cpp, ...) failed.
make (e=5): Access is denied.
make: *** [platform.o] Error 5
I've tried running eclipse as administrator, but that doesn't make any difference. Any clue how to fix this?
My windows PATH variable is C:\WinAVR-20100110\bin;C:\WinAVR-20100110\utils\bin;c:\Program Files (x86)\NVIDIA Corporation\PhysX\Common;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\;C:\Program Files\Java\jre6\bin\;C:\cygwin\bin
C:\cygwin\bin\g++.exe is a Cygwin symbolic link pointing to either g++-3.exe or g++-4.exe. Native Windows functions such as CreateProcess() don't understand Cygwin symbolic links though. Hence you need to configure Eclipse to execute g++-3.exe or g++-4.exe directly.
