Tcl support is not built automatically. You must have Tcl installed on the machine. You should use at least version 8.5. These notes assume that Tcl is installed as d:/tcl but you can change that if you want.

The Tcl library must be built as the same build type as the Berkeley DB and Berkeley DB XML libraries (both Release or both Debug). We found that the binary release of Tcl can be used with the Release configurations of Berkeley DB and Berkeley DB XML, but you will need to build Tcl from sources for the Debug configuration. Before building Tcl, you will need to modify its makefile to make sure that you are building a debug version, including thread support. This is because the set of DLLs linked into the Tcl executable must match the corresponding set of DLLs used by Berkeley DB and Berkeley DB XML.
