Compile error in TclModelBuilder

[dynaryu]

I got error message as shown below during compiling OpenSees.

TclModelBuilder.cpp: In constructor `TclModelBuilder::TclModelBuilder(Domain&,
Tcl_Interp*, int, int)':
TclModelBuilder.cpp:314: error: invalid conversion from `int (*)(void*,
Tcl_Interp*, int, char**)' to `int (*)(void*, Tcl_Interp*, int, const
char**)''

Do you have any idea of how to correct it ??
Any help would be greatly appreciated.

you need -D_TCL84 in your C++ flags or go into OPS_Globals.h and set TCL_Char to be const char.
