I answered, but if you cannot fix it you will have to post a relevant piece of code.

Solution 1

Apparently, you tried to re-define malloc somewhere. Find it in your code and exterminate. Do you know the difference between definition and declaration? C++ allows several declarations of the same thing; including is based on this rule, but multiple definitions will run into a link-time error like the one you show.

Solution 2

Apparently, you are using different runtime libraries. See this[^] article
