Eclipse C/C function 'printf' could not be resolved

Question

I\'m trying to set up a C/C++ development environment on Eclipse.

I installed the following Eclipse plugins:

• C/C++ development tools SDK
• Library A

Answer 1

You must include above your main(). This should solve it:

#include 
int main() {
    printf("Hello World!!!");
    return 0;
}

Sometimes, Eclipse's parser gets stupid. You can try reparsing the project. Right click on your project then → Index → Rebuild. After rebuild, most likely the symbols will be recognized.
