Re: although %renamed "Can't wrap fun<(X)> unless renamed..."

Thank you for the suggestions.

Unfortunately it doesn't help me to suppress the warnings. Firstly, I must
have a working wrapper of the friend function. Secondly, this single problem
is the source of a huge number of swig errors that are caused by the friend
function which is missing in the wrapper code.

Therefore I'm still looking for explanations to understand the problem, or
even better for help how to solve it and have the friend function wrapped in
the interface.

Thank you,
Patrick

You're not instantiating the template function.  Put

%template(intfriendfun) friendfun<int>;

toward the end of your interface file.

Ahh, right. The warning about the friend is just a red herring. You get
that warning regardless of whether the friend is a valid identifier or
not, regardless of whether it is renamed or not, and regardless of
whether friendfun gets wrapped or not.

You're absolutely right. This solved the problems. (I thought I tried this
earlier and had even more error messages, but apparently I didn't.)

Can someone still comment on my observation (see first post in this thread),
that the posted code only works with swig 1.3.31:
>(This was done with swig 1.3.31. With version 1.3.33 there are more
problems causing an error until I 
>remove the "<X>" in the line  "friend void friendfun <X> (X arg);" of the

Or can anybody run the latest version of swig on my example without getting
a syntax error?

Thank you
Patrick

The latest does not give a syntax error, but it does give a warning:

example.i:18: Warning(503): Can't wrap 'friendfun<(X)>' unless renamed 
to a valid identifier.

which strikes me as unwarranted. I suggest you filter the warning as 
below. Can you add this testcase into the bug tracker?

%warnfilter(503) friendfun;

although %renamed "Can't wrap fun<(X)> unless renamed..."


Hello,
I had some problems with template functions that are declared friends to
template classes. I reduced the code to the snippet below. Running swig
says:
>$swig -c++ -python test.i
>test.h:9: Warning(503): Can't wrap 'friendfun<(X)>' unless renamed to a
valid identifier.
>$
I don't understand this warning, because the instantiated friendfun *is*
renamed ("%rename(intfriendfun) ::friendfun<int>;").
What is wrong, and how do I get rid of the warning?

--- test.h ---
template<class X> void friendfun (X arg){};

template<class X> class Test{
  int counter;
public:
  Test(int init){
    counter=init;
  };
  friend void friendfun <X> (X arg);
};

Re: although %renamed "Can't wrap fun<(X)> unless renamed..."

SWIG has a weird habit of trying to wrap friend declarations, or at
least doing something other than just ignoring them as it ought to.

I have the following friend declaration in my "MapControlPainter" class
(don't ask ;)):

friend void SWIGSTDCALL CSharp_MapControlPainter_ResizeViewport(void *
jarg1, int jarg2, int jarg3);

SWIG says the same thing:

..\..\Control\MapControlPainter.h(167): Warning(503): Can't wrap
'Navi::CSharp_MapControlPainter_ResizeViewport' unless renamed to a
valid identifier.

so I surround it with a "#ifndef SWIG" block.

I have no idea why the warning appears, but you can selectively tell SWIG
to ignore warnings.

#pragma SWIG nowarn=503

I have no idea why the warning appears, but you can selectively tell SWIG
to ignore warnings.

#pragma SWIG nowarn=503

or

%warnfilter(503) MyClass;

Re: although %renamed "Can't wrap fun<(X)> unless renamed..."

Thank you for the suggestions.

Unfortunately it doesn't help me to suppress the warnings. Firstly, I must
have a working wrapper of the friend function. Secondly, this single problem
is the source of a huge number of swig errors that are caused by the friend
function which is missing in the wrapper code.

Therefore I'm still looking for explanations to understand the problem, or
even better for help how to solve it and have the friend function wrapped in
the interface.

Thank you,
Patrick

You're not instantiating the template function.  Put

%template(intfriendfun) friendfun<int>;

toward the end of your interface file.

Ahh, right. The warning about the friend is just a red herring. You get
that warning regardless of whether the friend is a valid identifier or
not, regardless of whether it is renamed or not, and regardless of
whether friendfun gets wrapped or not.

You're absolutely right. This solved the problems. (I thought I tried this
earlier and had even more error messages, but apparently I didn't.)

Can someone still comment on my observation (see first post in this thread),
that the posted code only works with swig 1.3.31:
>(This was done with swig 1.3.31. With version 1.3.33 there are more
problems causing an error until I

Or can anybody run the latest version of swig on my example without getting
a syntax error?

Thank you

The latest does not give a syntax error, but it does give a warning:

example.i:18: Warning(503): Can't wrap 'friendfun<(X)>' unless renamed 
to a valid identifier.

which strikes me as unwarranted. I suggest you filter the warning as 
below. Can you add this testcase into the bug tracker?

although %renamed "Can't wrap fun<(X)> unless renamed..."


Hello,
I had some problems with template functions that are declared friends to
template classes. I reduced the code to the snippet below. Running swig
says:
>$swig -c++ -python test.i
>test.h:9: Warning(503): Can't wrap 'friendfun<(X)>' unless renamed to a
valid identifier.
>$
I don't understand this warning, because the instantiated friendfun *is*
renamed ("%rename(intfriendfun) ::friendfun<int>;").
What is wrong, and how do I get rid of the warning?

--- test.h ---
template<class X> void friendfun (X arg){};

template<class X> class Test{
  int counter;
public:
  Test(int init){
    counter=init;
  };
  friend void friendfun <X> (X arg);
};

Re: although %renamed "Can't wrap fun<(X)> unless renamed..."

SWIG has a weird habit of trying to wrap friend declarations, or at
least doing something other than just ignoring them as it ought to.

I have the following friend declaration in my "MapControlPainter" class
(don't ask ;)):

friend void SWIGSTDCALL CSharp_MapControlPainter_ResizeViewport(void *
jarg1, int jarg2, int jarg3);

SWIG says the same thing:

..\..\Control\MapControlPainter.h(167): Warning(503): Can't wrap
'Navi::CSharp_MapControlPainter_ResizeViewport' unless renamed to a
valid identifier.

so I surround it with a "#ifndef SWIG" block.

(don't ask ;)):

friend void SWIGSTDCALL CSharp_MapControlPainter_ResizeViewport(void *
jarg1, int jarg2, int jarg3);

SWIG says the same thing:

..\..\Control\MapControlPainter.h(167): Warning(503): Can't wrap
'Navi::CSharp_MapControlPainter_ResizeViewport' unless renamed to a
valid identifier.

so I surround it with a "#ifndef SWIG" block.

I have no idea why the warning appears, but you can selectively tell SWIG
to ignore warnings.

#pragma SWIG nowarn=503

or

%warnfilter(503) MyClass;

Re: although %renamed "Can't wrap fun<(X)> unless renamed..."

Thank you for the suggestions.

Unfortunately it doesn't help me to suppress the warnings. Firstly, I must
have a working wrapper of the friend function. Secondly, this single problem
is the source of a huge number of swig errors that are caused by the friend
function which is missing in the wrapper code.

Therefore I'm still looking for explanations to understand the problem, or
even better for help how to solve it and have the friend function wrapped in
the interface.

Thank you,
Patrick
