Hi Alan, Returning to this old topic. Thank you for this fix which also enables me to also compile the smoke bindings. Unfortunately however they are "empty" in the sense that they contain no symbols specifically related to PLplot. I was expecting to see symbols containing QtPLDriver, QtPLWidget and QtExtWidget. You can verify this by running: nm -gC libsmokeplplotqt.so It appears to me as though what is happening is that smoke is parsing the include/qt.h file in an environment where PLD_qtwidget and PLD_extqt widget are not defined. I'm not sure why this is happening since these qt devices are getting built. As I had done in a different project, I tried to define these in bindings/qt_gui/smoke/plplotqt.h, but now they are either being ignored or over-written during the build. > more plplotqt.h #define PLD_qtwidget #define PLD_extqt #include "qt.h" Any thoughts on how to proceed?
