Compile error

[jkrueger1]

Installed version of qwt: current version (r2523), using Qt 4.8.4, sip 4.15.5

after 'python configure.py' and calling make I got:

./sipQwtQwtAlphaColorMap.cpp: In member function ‘QVector sipQwtAlphaColorMap::colorTable(const QwtInterval&) const’:
./sipQwtQwtAlphaColorMap.cpp:69:47: error: no matching function for call to ‘sipQwtAlphaColorMap::colorTable(const QwtInterval&) const’
return QwtAlphaColorMap::colorTable(a0);
^
./sipQwtQwtAlphaColorMap.cpp:69:47: note: candidate is:
In file included from qwt_color_map.sip:82:0:
/home/jkrueger/qwt/include/qwt_color_map.h:79:27: note: virtual QVector QwtColorMap::colorTable(int) const
virtual QVector colorTable( int numColors ) const;
^
/home/jkrueger/qwt/include/qwt_color_map.h:79:27: note: no known conversion for argument 1 from ‘const QwtInterval’ to ‘int’
make: *** [sipQwtQwtAlphaColorMap.o] Error 1

After having a look into the code and qwt code I found out that the Qwt call to the colorTable has an integer parameter now.

Hi

I'm sorry for a late answer. Had a showstopper in the project that is now solved.

I cannot reproduce your bug. I have tested with sip 4.19.7 and Qt4.8.7 (Debian)
and it compiles without errors.

I'm trying to compile this using qt5. I'm getting the following error:

Hi

Sorry for a late answer but this looks like you have not used the patched Qwt header files.
See README.
