Opening xclearcase or running clearimport reports error: Input in flex scanner failed

Troubleshooting


Problem

This technote explains why the error, Error: Input in flex scanner failed, occurs while attempting to open the IBM® Rational® ClearCase® xclearcase graphical interface on Linux® or running clearimport.

Symptom


This error is reported when trying to open the xclearcase graphical user interface (GUI) on Linux or when running clearimport:

Error: Input in flex scanner failed

Cause


Possible causes for the error include the following:

  1. It was determined that the variable ICON_PATH was incorrectly defined in the user's shell and was conflicting with xclearcase.

    Example:
    setenv ICON_PATH /usr/ccase_rls/icon: $ATRIAHOME/config/ui/icon

    Note: In this example there is a period missing before the word icon (.icon).

  2. This issue has also been seen on Linux clients running ClearCase 7.0.x if there is another .icon file present in either /opt/rational/clearcase/config/ui/icon/ or ~/.icon/.

    This issue has been reported as a product defect under APAR PK69581.
  3. Your are running clearimport and have unicode (extended ASCII) characters in your magic file.

Resolving The Problem



For Cause 1

    The correct syntax is as follows:

    home-directory/.icon:$CLEARCASEHOME/config/ui/icon


    Review the ClearCase Command Reference Guide on the topic of env_ccase (cleartool man env_ccase) for more information about the ICON_PATH variable.


    WORKAROUND

    Comment out the variable in your shell for xclearcase to work as expected.


For Cause 2
    Defect APAR PK69581 has been closed and the decision was made by Product Management to exclude the resolution of this feature enhancement from future upgrades. The following workaround below should be used.

    WORKAROUND

    Any entry in .icon file must be concatenated into default.icon


For Cause 3
    Check your magic file for the presence of unicode characters.
