Hi Richard: Thanks for the reminder of the older discussion of similar issues for the qt device driver. I just took a quick peek at that very long thread, and it appears you got excellent test results by using the workaround TEST_DYNDRIVERS=OFF. In other words, you were getting a non-zero return code from test-drv-info that was an apparently false warning that something was wrong with the qt device driver linking (since all your extensive tests that did not involve test-drv-inf worked fine). And I am currently getting similar false warnings from wxwidgets for test-drv-info. So we apparently have a situation where our normal dynamic loading of the device works properly from the plplotd library, but not when we do a test of that loading using test-drv-info. So there must be some difference between the dynamic loading done in test-drv-info and the plplotd library, but I cannot spot what it is. Anyhow, I am now exploring the possibility of trying more complete error reporting in src/ltdl_win32.c. Perhaps that will reveal more exact details when anything goes wrong in the linking of wxwidgets (and qt) and help to reveal what the test-drv-info issue is on Windows.
