Thanks, Werner. However, I found the result did not compile on Linux. Here was the error message: In file included from /home/software/plplot_cvs/HEAD/plplot_cmake_qt/bindings/qt_gui/plqt.cpp:34: /home/software/plplot_cvs/HEAD/plplot_cmake_qt/include/qt.h:92: error: invalid use of ‘extern’ in linkage specification That line had a double extern (which I have never heard of). I replaced that with a single extern (revision 10586), that is -extern "C" extern PLDLLIMPEXP_DRIVER_DATA( const char* ) plD_DEVICE_INFO_qt; +extern "C" PLDLLIMPEXP_DRIVER_DATA( const char* ) plD_DEVICE_INFO_qt; and gcc was happy again, and all the qt device tests (done with the newly implemented test_all_qt target accessible if you use -DBUILD_TEST=ON) went fine. Hopefully, the Windows native compiler does not demand the double extern and that was merely a typographical error introduced in the original patch that the Windows native compiler tolerated before. Please let me know it that is the case. Alan __________________________ Alan W.
