Current having issues with Eclipse. I installed eclipse oxygen (32 bit), installed Cygwin and MinGW (Yes I updated the catalog), both compilers are found by Eclipse. I made a new project> Executable > Empty Project (Used both Cygwin GCC and MinGW GCC) > New Source > Built the project > "Run as" > Local C/C++ Applications > "Launch Failed. Binary not found."

As you can see I have two projects, one uses Cygwin GCC along with the Cygwin Parsers. The other uses MinGW GCC with the PE Windows Parser (Tried it with the Cygwin Parser just to see) Still, nothing worked. What am I missing?

Part of the problem is that the build failed to create an executable so it can't be found.
It had an undefined reference to WinMain which is the entry point for a Windows GUI
For some reason, you are trying to build a GUI program instead of a console program.
Not sure why.
If you post the build log there might be some indication.

This may provide some help: https://stackoverflow.com/questions/5259714/undefined-reference-to-winmain16

Alternately, try creating the ANSI Hello World project using:
File --> New --> C/C++ Project --> C Managed Build --> Executable --> Hello World ANSI C Project with the MinGW GCC toolchain.
Then compare it to the one you created.

Honestly I forgot because I eventually just used a different environment but I would try to follow the stack overflow link.

I know this is an old post, but i keep having the same problem and I only see the same solutions in every forum. I tried all of it but I still get this problem every once in a while.

I made sure the paths for the compiler is set up, the binary parsers is ticked according to my OS, and I saved and built the program, BUT I still get that error.

I realized that the binary file and debug folder won't build if there are capital letters in the C file name. So, I just USE LOWER-CASE LETTERS FOR THE C FILE NAME and it works all the time.

Hope this helps !
