I have been working on C++ for few years now and have compiled stuff several times but the following issue is totally new to me and it just doesn't make sense.
Following are the steps i am following:
Any pointers to what might be going wrong here?
Following is the code which compiles:
#include "iostream"
#include "thread"
#include "mutex"
using namespace std;
class threadFunctor{
public:
};
int main(int argc , char** argv){
cout << "Hello";
return 0;
}
Following code gives error:
#include "iostream"
#include "thread"
#include "mutex"
using namespace std;
class threadFunctor{
public:
};
int main(int argc , char** argv){
cout << "Hello World";
return 0;
}
Following is a snippet of the errors generated:

By doing #include "thread"
, you've said (by convention at least) to check the current directory for a thread
file first. The problem is that you have a thread
file in your current directory. Presumably, it's your executable from the first time you compiled. This is apparent by the errors, which explicitly say ./thread
.
You should include all standard headers via #include <thread>
rather than #include "thread"
- you never want to search elsewhere first for standard headers.
