 Try tonight's SIP snapshot. It's a problem with the new implicit copying of
 const reference results.


This morning I checkout out pykde revision 959021 and tried to build it
against kde-4.2.2 and the most recent SIP/PyQt4 snapshots. qhostinfo.h can
not be found during make, but the file is present on my system in both
/usr/include/qt4/QtNetwork/ and /usr/include/qt4/Qt/. Is it possible to
build pykde with the riverbank snapshots and kde-4.2.2? Could anyone please
advise?

Thanks,
Darren

[PyQt] Regression in SIP sip-4.8-snapshot-20090409 wrt MappedTypes

2009-04-19 Thread Simon Edwards 

Hello Phil,

I'm working on getting PyKDE4 trunk working on SIP 4.8 and PyQt 4.5 and 
hit what looks like a fairly straight forward regression bug.


The compile error is:

/home/sbe/devel/svn/kde/trunk/KDE/kdebindings/python/pykde4/sip/kdecore/typedefs.sip: 
In function ‘int convertTo_KSharedPtr_0200DNSSD_RemoteService(PyObject*, 
void**, int*, PyObject*)’:
/home/sbe/devel/svn/kde/trunk/KDE/kdebindings/python/pykde4/sip/kdecore/typedefs.sip:247: 
error: ‘sipForceConvertTo_DNSSD’ was not declared in this scope 

/home/sbe/devel/svn/kde/trunk/KDE/kdebindings/python/pykde4/sip/kdecore/typedefs.sip:247: 
error: expected ‘,’ or ‘;’ before ‘::’ token 



The offending C++ code is:

DNSSD::RemoteService *cpp = (DNSSD::RemoteService 
*)sipForceConvertTo_DNSSD::RemoteService (sipPy, iserr);


which was expanded from the mapped type:

---
template TYPE
%MappedType KSharedPtrTYPE
{
// ... etc etc ...

%ConvertToTypeCode
// Convert a Python instance to a Ptr on the heap.

if (sipIsErr == NULL)
return PyInstance_Check(sipPy);

int iserr = 0;
TYPE *cpp = (TYPE *)sipForceConvertTo_TYPE (sipPy, iserr);
// ... etc etc ...
---

elsewhere in the sip files I've got this which sets it all in motion:

typedef KSharedPtrDNSSD::RemoteService Ptr;

cheers,

sipForceConvertTo_*() (and related functions) are internal and should not
be used by handwritten code. If it isn't documented then you can't use it.

For SIP prior to v4.8 you should use sipForceConvertToInstance(). For v4.8
then sipForceConvertToType() is preferred (though the former will be
supported for all SIP v4.x versions). The advantage of the latter is that
it will automatically handle (for example) QString when it is implemented
as a wrapped class or a mapped type.
