I am new to eclipse. I tried creating new C++ project through File-> New -> C++ Project -> Hello World C++ Project. When I try to launch it, it gives me error:

Launch Failed, Binary not found.

However, when I right click on the project, choose the Build Project option, and then press the launch button, the hello world program executes successfully.

I have tried enabling the build automatically options at each place specified by this link . Still it doesn't work for me unless I manually build it.

Is it mandatory to build it manually at first before it can be launched? I don't have any such problem when using eclipse for java projects.

I am using Eclipse Luna version 4.4.

Did you research on Eclipse's site if there's a bug reported for this behavior? – πάντα ῥεῖ Sep 06 '14 at 18:00
yes, but nowhere I could find such a bug reported. Even I am not sure if this is a bug. – shivshnkr Sep 06 '14 at 18:09
Is auto build enabled? – Basilevs Sep 06 '14 at 18:15
i tried whatever I could, followed this link: http://stackoverflow.com/questions/23959595/how-to-enable-eclipse-to-autobuild-autosave-changes-before-run-cdt – shivshnkr Sep 06 '14 at 19:04
@Basilevs auto-build, where should I enable? – shivshnkr Sep 06 '14 at 19:52
when I create a C project in eclipse, I have to build it 'manually' the first time. Thereafter, when I edit anything and click run/run it rebuilds itself and runs. – user3629249 Oct 11 '15 at 20:20
