[Swig-user] stumped by why some typemaps work and others don't

[Leo L. <le...@si...>]

Hi Folks,

After a long absence, I tried to add another class to my swig-based
interface to Coin-OR, and am stumped by why passing vectors works in
one example and not on the other.

I get an error regarding the number of arguments, which is correct.
Google has been some help, but not enough to crack the problem.

The function that works is:
---
class OsiCbcSolverInterface  {
public:
    virtual void loadProblem(const int numcols, const int numrows,
			     const CoinBigIndex * start, const int* index,
			     const double* value,
			     const double* collb, const double* colub,
			     const double* obj,
			     const double* rowlb, const double* rowub) ;
};
---

The function that doesn't is:

---
class CoinPackedVector{
public:
   virtual void setFull(int size, const double * elems,
		bool testForDuplicateIndex = false);
};
---

The text below is the use case. Following it is the output:

---
import osi
cbc = osi.OsiCbcSolverInterface()
inf = 1000
m,n = 3,2
c, lb, ub = [3,2], [0,0], [inf,inf]
start, index, val= [0,3,5], [0,1,2,0,1], [2,1,1,1,1]
lhs, rhs= [-inf,-inf,-inf],[100,80,40]
cbc.loadProblem(n,m,start,index,val,lb,ub,c,lhs,rhs)
cpv = osi.CoinPackedVector()
cpv.setFull(3,[1,2,3])
---
[user@host swimpy]$ python swigBugUseCase

'CoinPackedVector_setFull'.
  Possible C/C++ prototypes are:
    setFull(CoinPackedVector *,int,double const *,bool)
    setFull(CoinPackedVector *,int,double const *)
---

The libraries I am trying to wrap are part of Coin-OR. Here is a link
to the doxygen corresponding to the classes:

http://www.coin-or.org/Doxygen/Osi/class_osi_solver_interface.html
http://www.coin-or.org/Doxygen/Osi/class_coin_packed_vector.html

I have also attached three files: a paired down version of the .i that
contains only the two offending functions; the Makefile I use; and the
use case above. Please let me know if anyone can help or if there is
any other piece of information I can provide.

Thanks in advance!
Leo.
