On some systems 'make check' will report that the script config.guess' could not be found. If that happens, create a symbolic link from ../conf/config.guess to either this directory or the libdap-* directory (one level up). The check target should now work. Tests that are known/expected to fail There are four tests that are know to fail: expr-test.0/test.1.exp, test.6.exp and the expr-test.1 versions. These tests check to see if a CE with a selection works when applied to a non-relational data type. It does not work and that behavior was never defined by DAP 2.0. Tests expr-test.1/test.xc.exp and test.yc.exp also fail because of the situation described in ticket #995 - a nested sequence is not correctly processed by the intern_data() methods. This problem will show up in the JGOFS handler when ASCII responses are requested, but will not affect other Sequence data sets such as the file servers' data.
