So I have an interesting problem with Eclipse Galileo. I use it for Java, C++ and C programming. The first two work flawlessly: everything runs just like it should. C is where I have issues.
1.) I can't ever get it to build a binary, ever. So I've taken to using the included HelloWorld.c template and building whatever I'm doing off of that. If I use the template, everything works. If I don't, it can't build a binary. I have no idea why. C++ projects build just fine.
2.) When running C programs, it will take ALL input for the entire program (I've just been building simple stuff) BEFORE it displays any text at all. This is making it exceptionally difficult to debug my code. How do I get it to run like it does in the actual console, i.e. text, prompt, entry, execute?
Thank you all in advance, I appreciate any help you can give me. This is the first time I've really coded C, but I've developed in Java , VB and C++ for years and been using Eclipse for about a year - something I'd like to continue doing, since the other C IDEs really, really suck.
Again, my thanks!
Devon

It doesn't matter what order I list anything in, if I have it nested in a called function, whatever. The scanf functions of the entire program have to have input before ANY output is generated in console.

This is precisely the behavior that the FAQ referenced by Alex refers.
