Hi Hazen: I found the source of those: irwin@raven> find /usr/include/qt4/ -type f |xargs grep -il "qMetaType.*Helper" /usr/include/qt4/QtCore/qmetatype.h /usr/include/qt4/Qt/qmetatype.h If someone conversant with C++ looked at those headers for instances of the regex pattern qMetaType.*Helper (of which there are about 30), I assume they would find some problematic C++ syntax that g++ can handle, but which makes the smoke C++ code parser choke. So this is actually probably a fairly serious issue that makes parts of Qt inaccessible to smoke bindings. It apparently does not affect us (since PLplot uses such a small subset of Qt), but nevertheless it should probably be a good idea to bring this issue to the attention of the smoke developers as well as the -I issue.
