gcc template error

Question

why in the first line of this code:

template <typename VectorType>
std::string repr_vector_dynamic(const VectorType* vect)
{
    std::stringstream strs;
    strs << "(";
    for (int i = 0; i < vect->size(); ++i) {
        if (0 != i) {
            strs << ", ";
        }
        strs << (*vect)[i];
    }
    strs << ")";
    return strs.str();
}

I always get thsese errors at the first line: (MinGW gcc 4.5)

expected ';' before 'template'

expected primary-expression before 'template'

thx

later edit: here is the command line / log I got from eclipse:

Answer 1

expected ';' before 'template'
expected primary-expression before 'template'

You forgot a semicolon before the first line. Can you give the previous line ?

Answer 2

Maybe you should be using g++, the C++ compiler, instead of gcc, the C compiler.

Another possibility is that one of your headers has #defined a truly evil macro.

Answer 3

As others have suggested, it is what comes before the template declaration that is missing the ;.

Take a look at what the compiler sees, thus:

g++ -E <yourfile>.cpp | less

Answer 4

The errors that you have posted suggest that the problem is within the function void init_module_PyCML(). It would therefore appear that you have tried to define a function template within the body of another function.

For example trying to compile the following code gives me the same error

void f()
{

template < typename T >
void g()
{
};

}

The last error line suggests that perhaps you have forgotten the closing } for init_module_PyCML()?
