I''m trying to compile a simple example with boost:

ython using g++ as opposed to using bjam. When I compile I get:


var.cpp:14: `init'' was not declared in this scope
var.cpp:14: parse error before `>'' token
var.cpp:15: ISO C++ forbids declaration of `class_'' with no type
var.cpp:15: template-id `class_<Var>'' in declaration of primary template
var.cpp:16:44: warning: no newline at end of file

My source code is:


var.cpp:14: `init'' was not declared in this scope
var.cpp:14: parse error before `>'' token
var.cpp:15: ISO C++ forbids declaration of `class_'' with no type
var.cpp:15: template-id `class_<Var>'' in declaration of primary template
var.cpp:16:44: warning: no newline at end of file

So I''m assuming that I haven''t included a certain header file, but which one is it? Any help appreciated. Thanks

You posted the error messages twice, seeing your code would be more helpful

"Debugging is twice as hard as writing the code in the first place. Therefore, if you write the code as cleverly as possible, you are, by definition, not smart enough to debug it." — Brian W. Kernighan

Oh no! I didn''t notice that! lol

I just re-installed Linux, so let me see if I can restore the source.

Here you go! lol

#include <boost/python/module.hpp>#include <boost/python/def.hpp>using namespace boost::python;#include <string>class Var    {        Var(std::string name) : name(name), value() {}        std::string const name;        float value;    };class_<Var>("Var", init<std::string>())      .def_readonly("name", &Var::name)      .def_readwrite("value", &Var::value);

Ok, I realize this is a bit old, but let me just point out something...

BOOST_PYTHON_MODULE(some_name_here)
{
// NOW put your class defs here
class_(...)
...
;
}
