If there is a problem in parsing an input file, just SETENV LOGLEVEL 10 and you will see how each attribute is being parsed. This usually suffices to solve the problem.
6119:Inducer: rld: Fatal Error: cannot successfully map soname 'libMWrapper.so' under any of the filenames /usr/lib/libMWrapper.so:/lib/libMWrapper.soMLC++ uses dynamically shared objects. The runtime loader must know where these are through the environment variable LD_LIBRARY_PATH. Add setenv LD_LIBRARY_PATH "/usr/lib:/lib:$MLCDIR"
After you set MLCDIR to the MLC++ directory. Another alternative is to move all the files ending with .so into /usr/lib.
Error - LinearDiscriminant::LinearDiscriminant: Number of categories 7 != 2.The inducer you are running attempts to generate a LinearDiscriminant for more than two categories. Remember that perceptron and winnow are limited to two-class problems.

$MLCDIRis not defined to be the path where MLC++ is installed. Specifically, c45 results are parsed using the c45test.awk script.
Error - FileNames::test_file: No TESTFILE specified.
A TESTFILE must be specified if the DATAFILE ends with the ``.all'' suffix. If you are following the MLC++ naming conventions, then you are probably doing something wrong. A ``.all'' suffix indicates that all your data is in the given file, so no TESTFILE should be available. You may be running the Inducer utility instead of the AccEst utility.
Error - mlcIO::file_exists: File '.names' does not exist in colon separated paths '.:/u/mlc/db:'.An empty DATAFILE was given.
