Please Help Me.
The error C2220 simply means “Warning treated as error - no object file generated” (due to the /WX
flag being set).
The warning that causes this error is C4819, which says
The file contains a character that cannot be represented in the current code page ( number ). Save the file in Unicode format to prevent data loss.
(And that seems to match the message that is printed in the console, as far as I can match the output with that of translating this text into Chinese with Google Translate…)
It refers to Property.h(1,1)
, and thus, certainly does not point out where the problematic character appears - but let’s assume that it at least really refers to this file, and just wants to tell us that there is a problematic character somewhere in the file. And… if I had to take a guess, I’d say that it does not like the ⨉
in comments like “MATN
is an N ⨉ N
matrix”. If this is the culprit, it could probably be changed to be an x
.(We all � Unicode, right?)
