[Discuss-gnuradio] Having difficulty with compiling in Ubuntu 8.04...

[Rob Frohne]

Hi All,

I'm having difficulty compiling in Ubuntu 8.04 because some stuff from 
QT isn't found, for example, qmemarray.h, which I can find in 
/usr/include/qt3/qmemarray.h, however, I thought it should be using QT4 
instead of QT3, and I have installed qwt 5.0.2-2 from the Ubuntu 
repository.  As of January 2008, the wiki says you must compile from 
source, but it looks like it is in the repository now.  The interesting 
thing, is I have another machine running 8.10 instead of 8.04, and the 
header file is only in the same qt3 location there, but it builds just 
fine.  Here is the code calling for that header:

/*!
 \def QwtArray
 Aliases QArray (Qt-2.x) and QMemArray (Qt-3.x) to QwtArray
*/
#ifdef QWT_NO_MEMARRAY
#include <qarray.h>
#define QwtArray QArray
#else
#include <qmemarray.h>
#define QwtArray QMemArray
#endif

Perhaps QWT_NO_MEMARRAY is set in 8.10 and not in 8.04.

Any tips would be appreciated.

Thanks,

Rob
