I am using following code
1) File : example.i
%module example
%{
/* Put header files here or function declarations like below */
#include "example.h"
%}
%include "example.h"
2) File example.h
enum Type {one,two};
class myClass {
public:
myClass() {}
static bool printVal(int val);
static bool printEnum(Type val);
};
3) File example.cpp
#include "example.h"
#include <iostream>
using namespace std;
bool myClass::printVal(int val) {
cout << " Int Val = " << val << endl;
return 0;
}
bool myClass::printEnum(type val) {
cout << " Enum Val = " << val << endl;
return 0;
}
Steps to compile and run
swig -c++ -tcl example.i
g++ -c -fpic example_wrap.cxx example.cpp -I/usr/local/include
g++ -shared example.o example_wrap.o -o example.so
setenv LD_LIBRARY_PATH /pathtoexample.so:$LD_LIBRARY_PATH
tclsh
% load example.so
%myClass_printVal 1
Int Val = 1
%myClass_printEnum one
TypeError in method 'myClass_printEnum', argument 1 of type 'type'
I am getting TypeError if I pass enum . I know there is typemap for type conversion , but I do not know how to use typemaps to pass enum values from TCL script to c++ class . I am looking forward for help for how to pass enum values from TCL to c++ class objects using SWIG.
According to the official documentation:
C/C++ constants are installed as global Tcl variables containing the appropriate value.
So you must refer to the enum value by dereferencing the corresponding variable:
% myClass_printEnum $one
Some examples of exposing C/C++ enums in Tcl are a available at http://doc.gnu-darwin.org/enum/
