Question: I get an exception:"Variant or safe arrays out of bounds" on selecting any records sorted by "ORDER BY [NAME]" (in Kylix 3). What should I do?

Answer: This is Kylix bug. Do each of the below-mentioned steps, otherwise the error will remain.

  1. {$KYLIX} is a subdirectory where the IDE is installed (i.e. /home/svd/kylix3 by default). Completely delete this directory with the old FIBPlus version and all *.so,*.dcu,*.dpu files of this library (if there are any in another directory.
  2. Open the console under User name (not root).
  3. Find the file {$KYLIX}/source/rtl/sys/VarUtils.pas, and change two lines in the line 1499:
    .....
    Result^.Bounds[LDim].ElementCount := Bounds[DimCount - LDim - 1].ElementCount;
    Result^.Bounds[LDim].LowBound := Bounds[DimCount - LDim - 1].LowBound;
    ....
    replace by
    .....
    Result^.Bounds[DimCount - LDim - 1].ElementCount := Bounds[DimCount - LDim -1].ElementCount;
    Result^.Bounds[DimCount - LDim - 1].LowBound := Bounds[DimCount - LDim - 1].LowBound;
    ......
  4. Close the editor, saving all the changes and compile the module from the command line:
    >../../../bin/dcc VarUtils.pas
    After this you will see the file VarUtils.dcu in this directory. Simply COPY (!) it to the directories {$KYLIX}/lib and {$KYLIX}/lib/debug, by replacing the existing files there.
  5. Go to {$KYLIX}/source/rtl/
  6. Find the file GNUmakefile, open it in the editor, stand on line 26 and replace the BINDIR variable value by the one, used in {$KYLIX} (that is the directory with the Kylix installation)
  7. Close the editor and execute
    >make
    Then you will see the second package file, simply leave it, as it's not necessary .
  8. Go to the subdirectory {$KYLIX}/bin, find the file "bplrtl.so.6.9.0" and replace it by "bplrtl_old.so.6.9.0". Then find "bplrtl_user.so.6.9.0" and rename it to "bplrtl.so.6.9.0".
  9. Run Kylix and install the new FIBPlus packag

I've looked at FIBPlus and feel that it is one of the fastest (if not the fastest) IB components out there. Congratulations on doing such a fine job. >>
