Hi, I have compiled and installed MonetDB-11.21.11 (JUL2015-SP1) from pre-packaged source distribution. My environment is Ubuntu 14.04 LTS. I tried to run the test cases by the following command: $ sudo Mtest.py -r [package-name] I found that almost all tests PASSED when [package-name]=monetdb5, which is expected. But when I switched to [package-name]=sql, almost all tests FAILED. What is the reason? Or I did something wrong? Any idea would be helpful. Thanks. Best, Wenjian
