Could you confirm (1) when you run ..\dll\test-drv-info.exe qt > C:/plplot-5.9.7/build/drivers/test_dyndrivers_dir/qt.rc by hand there are no errors and you produce the above good result, while if (2) you run the same command automatically via cmake and "make VERBOSE=1" _in a fresh build directory_ you get run-time errors? If so, then the next question is what (e.g., PATH) is different between the two cases? Also, for the second case with run-time errors do you get the above qt.rc result or no result at all? > > I am running 64 bit Windows 7. > > So, can anyone help me with this, has anyone succeeded in running Plplot > with Qt under Windows 7? I am not sure whether it is related or not, but my own tests of the qt device under wine (the free [in both senses] implementation of Windows that is available under Linux) have been problematic. When I tried it for an old version of MinGW it worked fine. But once I moved to the modern version of MinGW (4.5.0-1) installed with the automatic mingw/msys installer, the qt device driver quit working. The (linking) issue was that the nokia downloadable Qt SDK contained an old version of MinGW that was incompatible with MinGW (4.5.0-1). This result was for a number of months ago, and I am sure that both MinGW and Qt SDK have been updated since, and they may be compatible now. But the point is that the version of MinGW in the Qt SDK should be the same as the version of MinGW that you have downloaded independently in order to get reliable results. Note that independent download and install of MinGW is necessary if you are interested in more languages (such as Fortran and Ada) than those supported by the Qt SDK version of MinGW. But if you are only interested in C and C++, I assume you could manipulate your PATH so that you exclusively used the Qt SDK version of MinGW. Alan __________________________ Alan W.
