<br>
If the VTK build is looking for a function called Tcl_GetErrorLine(),<br>
that means that it is using a "tcl.h" for Tcl 8.6. This function doesn't<br>
exist in Tcl 8.5 or earlier versions of Tcl.<br>
<br>
My guess is that you have installed Tcl 8.6 on your system, and<br>
CMake has found the Tcl 8.6 headers, but is linking to the Tcl 8.5<br>
libraries in the System folder.<br>
<br>
Make sure that your CMakeCache.txt use the same framework for<br>
all the Tcl variables:<br>
<br>
TCL_INCLUDE_PATH:PATH=/System/Library/Frameworks/Tcl.framework/Headers<br>
TCL_LIBRARY:FILEPATH=/System/Library/Frameworks/Tcl.framework<br>
TCL_TCLSH:FILEPATH=/usr/bin/tclsh<br>
TK_INCLUDE_PATH:PATH=/System/Library/Frameworks/Tk.framework/Headers<br>
TK_INTERNAL_PATH:PATH=/System/Library/Frameworks/Tk.framework/PrivateHeaders<br>
TK_LIBRARY:FILEPATH=/System/Library/Frameworks/Tk.framework<br>
<br>
If you still have problems after setting your cache as shown above, then<br>
you might have to find and remove the tcl.h file that is causing the error.<br>
