Main function being mysteriously declared somewhere unknown

So I literally have the simplest C++ file on the planet, and it won't compile. I can't seem to figure out where main is being defined before, is it in some weird search path? I've searched around and haven't been able to get anything working.

#include <iostream>


int main(int argv, char* argv[]) {
    std::cout << "It worked!" << std::endl;
    return 0;
}

When I compile this happens:

g++ -c main.cpp -O3
main.cpp:4:31: error: conflicting declaration ‘char** argv’
 int main(int argv, char* argv[]) {
                               ^
main.cpp:4:14: error: ‘argv’ has a previous declaration as ‘int argv’
 int main(int argv, char* argv[]) {
              ^
main.cpp:4:5: warning: ‘int main(int)’ takes only zero or two arguments [-Wmain]
 int main(int argv, char* argv[]) {
     ^
make: *** [main.o] Error 1

Main function is not defined anywhere else. The parameters of the main function have same names. Change them.

It should be: 

  int main(int argc, char* argv[])

Both your parameters are currently called argv.
