c++ mysql xcode I need to compile something and use the MySQL C++ library. I have mysql and mysql++ already compiled, I won’t go over how to do that now. I added the following code to the top of my source: #include <mysql++.h> I got an error /Users/jhaddad/dev/search_engine/main.cpp:4:21: error: mysql++.h: No such file or directory Not cool. How to fix: In XCode, open up the project settings (under the project menu).
