How do I handle function templates in SWIG?

I am getting a "Syntax error in input" error using SWIG on the following line of code

template<typename T>
void print_vec(std::vector<T> vec, int length = -1);

in my .i file, I include the following line

%template(print_vec_int) print_vec<int>;

What am I doing wrong?

You are swigging C++ code, but telling swig it is C. You need to add -c++ to the swig command line.

swig -o x_wrap.cc -c++ -python x.i

If you are using SCons, then you need to update the SWIGFLAGS environment variable:

env = Environment(SWIGFLAGS=['-c++', '-python'])
