STL errors only in specific files

[jhessin]

I have discovered something very interesting when it comes to STL in CodeBlocks for windows.

I compiled the following Hello World program and it runs just fine - code completion even worked for the vector that I used:

Code

#include <iostream>
#include <vector>

using namespace std;

int main()
{
    vector<string> test;
    string myString = "Hello world in a vector!";
    test.push_back(myString);
    cout << test.at(0) << endl;
    return 0;
}

But when I tried to do something similar in another source file i.e. for a class:

Code

#ifndef TESTCLASS_H
#define TESTCLASS_H
#include <vector>

class testClass
{
    vector<int> master_list;
    public:
        testClass();
    protected:
    private:
};

#endif // TESTCLASS_H

I get the following Error:

Code

||=== Hello World++, Debug ===|
C:\Users\jhessin\Downloads\PortableApps\Projects\Hello World++\testclass.h|8|error: ISO C++ forbids declaration of `vector' with no type|
C:\Users\jhessin\Downloads\PortableApps\Projects\Hello World++\testclass.h|8|error: expected `;' before '<' token|
||=== Build finished: 2 errors, 0 warnings ===|

I have tried putting in #include <iostream>, but that does nothing. I don't know why but it seems that support for STL only goes as far as the main.cpp file.

support for STL only goes as far as the main.cpp file.

No. Just put std:: in front of vector<int> in the second source file. Notice the "using namespace std;" does that in the first source file.

However - this is neither related to Code::Blocks nor to code completion. So I am locking this topic now as it violates our forum rules. This is not a general programming board.
