I installed BADA SDK and I tried to compile a "hello world" program but it doesn't work. Every time the problem is "Launch failed. Binary Not Found". I installed the C++ compiler under MinGW and the problem still exists.
Seems to be a typical problem of Eclipse users. See here for the discussion on what you could do. The first thing to try is to BUILD your application. There should be a button.
PS: I hope you can read english.
