You can't declare it like this. Second, you wrote C++ code, and you are compiling it using C compiler (use g++ command instead of gcc). Third there is no such library glibc, I think you meant stdlib.h. The correct code might look like this: #include <iostream> #include <stdio.h> int main() { printf("Hello World. \n"); std::cout << "Hello\n"; return 0; } Arturas M.
