Compile problem: sort() cannot be used as a function!?

Hi, I am doing a project comparing run times of STL sorts to sorts i have written. I am having a really weird compiler error that looks like this:

Code:

---

main.cc: In function 'int main(int, char**)':
main.cc:56: error: 'sort' cannot be used as a function

---

Here is some of the code from my main:

Code:

---

switch(sort){
        case 'q':
            if(stl)
              sort(my_vect.begin(), my_vect.end());
            else
              quick_sort(my_vect);
            break;
        case 'm':
            if(stl)
              stable_sort(my_vect.begin(), my_vect.end());
            else
              merge_sort(my_vect);
            break;
...

---

when i comment out the line that calls sort() everything works fine... even stable_sort which is from the same library and uses the same parameters. Also i have another small program just one file that calls sort() and it works there fine. This is completely insane and i cannot figure it out and any hints would be great.
thanks

Code:

---

switch(sort){
        case 'q':
            if(stl)
              sort(my_vect.begin(), my_vect.end());

Possible confusion due to variable name being similar to function name? Try changing the name of the variable in your code to something else.

Code:

---

switch(sort){

Apparently you have a variable named sort. I suggest that you dont have a using namespace std directive or a using std::sort directive, but instead use the fully qualified names.

Code:

---

switch(sort){
        case 'q':
            if(stl)
              std::sort(my_vect.begin(), my_vect.end());
            else
              quick_sort(my_vect);
            break;
        case 'm':
            if(stl)
              std::stable_sort(my_vect.begin(), my_vect.end());
            else
              merge_sort(my_vect);
            break;
