I don’t suppose there’s a workaround I could use until if and when the restriction is removed? (For example hard-coding the value of WT_ROOT)
Yes, not a great idea, but workable of you remeber you did it!
Look for a line starting “define WT_ROOT……………………” somewhere above the line 141 mentioned in the erorr message and change it to whatever you need. You might need to experiment a little to get the right syntax (Im not near a PC to help with that just now).
