Hello I have decided to have another try with PunQLite, having failed to get it working before. For the record, I am using Windows 10 Home with all recent updates applied. I tried the following: 1. Download latest image of Moose 6.1 (Pharo 6.0 Latest update: #60507). 2. Search Catalog Browser for PunQLite, which is flagged as OK for Pharo 6.0, and select 'Install stable version'. 3. Check that the file unqlite.dll has been installed in the same folder as the image. 4. Run tests in PqDatabaseTests. 30 tests run, all red. 5. Try to run some tests manually. Enter 'PqDatabase openOnMemory' and 'doIt'. Result: 'Error: External module not found'. Looking at the Monticello Browser, I see that my image has ConfigurationOfPunQLite(TorstenBergmann.29) and PunQLite-Core(TorstenBergmann.28). This is the version chosen as stable by the Catalog Browser. Have I in fact got the right version? Do I have to do something with the .dll to make it visible to the .ffi call? Any suggestions gratefully received. Peter Kenny
