Howdy!
I'm having trouble that I've been wrestling with for the last couple of days. I've
poured over documentation, wrote and rewrote code, jumped up and down, and reached
wits end :). I'm hoping that some kind soul on the list might be able to offer a
suggestion...
I'm using sip version 4.0 (snapshot-20040310-SIP4-182) with
PyQt-x11-gpl-snapshot-20040311, and have been having no troubles at all with the
included code. I've written my own library, however, for interfacing with a capture
card and displaying the resulting images / converting them to numarrays. In any case,
I decided that the display was too slow and that I should use the Xvideo/XShm
extensions to improve the speed. I've discovered that including the X11 libraries
directly in my .h files works fine when I compile the library, but when I compile the
generated SIP code, the compile falls apart in an #include nightmare. Basically pages
and pages of this sort of thing scroll by:
In file included from /usr/share/sip/qt/qvariant.sip:201,
from sipDVCFormattedImageDisplay.h:57,
from sipDVCcmodule.cpp:10:
/usr/lib/qt3/include/qvariant.h:104: error: parse error before `int'
/usr/lib/qt3/include/qvariant.h:121: error: missing ';' before right brace
/usr/lib/qt3/include/qvariant.h:123: error: parse error before `)' token
/usr/lib/qt3/include/qvariant.h:124: error: destructors must be member
functions
Since the library compiles fine, I don't think there's anything wrong with my includes.
Here's the #includes header of the FormattedImageDisplay.h
#include <Python.h>
#include <qframe.h>
#include <qstring.h>
#include <qimage.h>
#include <X11/Xlib.h>
#include <X11/Xutil.h>
#include <X11/extensions/Xvlib.h>
#include <sys/shm.h>
#include <X11/extensions/XShm.h>
#include <X11/extensions/Xv.h>
#include <X11/extensions/XvMC.h>
#include <X11/extensions/XvMClib.h>
And, the relevant part of the sip config file:
%Module DVC
%Import qt/qtmod.sip
%ModuleHeaderCode
#include <numarray/numarray.h>
%End
class FormattedImageDisplay : QFrame {
%TypeHeaderCode
#include <FormattedImageDisplay.h>
%End
public:
FormattedImageDisplay( QWidget * /TransferThis/ = 0, const char * = 0 );
~FormattedImageDisplay();
void setSize(unsigned int,unsigned int);
int setImageByNumarray( SIP_PYOBJECT );
QString getXvExtentionVersion();
public slots:
void paintEvent( QPaintEvent * );
};
As you can see, right now, I'm not doing much :). If I put all of the X11 includes in
the .cpp file, everything copiles just keen. That won't do in the long term, though,
because some of the X11 data structures need to be part of the class.
Does anyone have any ideas or suggestions? They would be /greatly/ appreaciated.
Thanks!
Peace,
Gary
