Launch Failed Binary not found Eclipse for C in Windows
I even faced this error and searched a lot to fix. Fortunately, I figured it out myself.
The following are the things you need to make sure they are set:
Window > Preferences > C/C++ > New CDT project wizard > Makefile Project > Binary Parsers
a) Set it to PE Windows Parser if you are on windows.
b) Set it to Cygwin PE Parser if you are using Cygwin
c) Set it to Elf parser if you are using ubuntu
Window > Preferences > C/C++ > Build > Environment
Now click on "select" and select "Path" variable so that you add you path variables in Eclipse.
Now its all done!
All you have to do is write a test program and press Ctrl+B (Build all; there is a button on menu bar) and after that click "Run".
