dump image problem

Anonymous — Sun, 17 Jul 2011 14:38:43 -0000

I am using the package qwtplot3d and I encounter a nasty problem on my scientific linux. I can nicely display a surface but as soon as I want to print it with the io function described in the example mesh2 I get a couple of X11 messages telling me that an unknown extension is used. Could you tell me which extensions have to loaded with x11 besides glx ?

Trunk fails to build

Stephen Roderick — Fri, 23 Apr 2010 13:18:56 -0000

Trunk and 0.2.7 do not build on Mac OS X Snow Leopard nor Ubuntu Koala. The attached patches fix this.

I believe the first patch has been on the ML before.
The second one implements required virtual dtor's to keep the linker happy.
The last patch bypasses the missing "qwtplot3d.pri" file, by explicitly listing header and source files.

Makefile

Dennis — Sun, 18 Oct 2009 11:31:29 -0000

Maybe I am doing something wrong here but the Makefile seems incomplete for the "make install" phase. I run qmake, which creates the Makefile, then run make and that works just fine. But when make install is run; none of the libraries gets installed, just the docs. When the make/make install gets to the libraries, here is what I see;

fontconfig -lXext -lX11 -lQtCore -lz -lm -pthread -lgthread-2.0 -lrt -lglib-2.0 -lpthread -ldl
ln -s libqwtplot3d.so.0.2.6 libqwtplot3d.so
ln -s libqwtplot3d.so.0.2.6 libqwtplot3d.so.0
ln -s libqwtplot3d.so.0.2.6 libqwtplot3d.so.0.2
rm -f lib/libqwtplot3d.so.0.2.6
rm -f lib/libqwtplot3d.so
rm -f lib/libqwtplot3d.so.0
rm -f lib/libqwtplot3d.so.0.2
mv -f libqwtplot3d.so.0.2.6 libqwtplot3d.so libqwtplot3d.so.0 libqwtplot3d.so.0.2 lib/

It looks as though it throws them into the source tree /lib but then does nothing more with them, like install them to a prefix.

qwtplot3d-0.2.7 fails make

Dennis — Sat, 17 Oct 2009 14:25:57 -0000

Using gcc-4.4.2 and glibc-2.10.1, the make fails on;
src/qwt3d_function.cpp:80: error: 'stderr' was not declared in this scope

Adding #include <cstdio> to that file fixes the problem.

Color legend broken in perspective mode

Knut Franke — Wed, 05 Mar 2008 12:49:11 -0000

In perspective mode, the color legend is malproportioned and the legend axis is displayed at an angle, crossing through the gradient. Tested with QwtPlot3D 0.2.7 and Qt 4.3.3.

Probably the easiest way to reproduce this is to patch the simpleplot demo:
