  Patches:
  • tkgate-1.6.patch1
    Fixes problems with the configuration script on some systems by reverting to the configuration method used in version 1.5c and earlier. The configure script distributed with 1.6 was intended to be able to automatically determine which version of tcl/tk to use, but the tests do not seem to work on all systems. Use this patch only if you were unable to configure tkgate with the original configure script.
  • If you are able to configure without the patch above, there may still be a problem in installing the "menagerie cpu" example. To fix this, edit the file "Imakefile" in the top directory and look for the line:

    EXAMPLE4=TKGATE_EXAMPLE4
    

    add the line:

    EXAMPLE5=TKGATE_EXAMPLE5
    

    after it and then re-configure/compile/install to get the menagerie cpu example. This change is only necessary if you did not apply the patch above.
