Question

I’ve a project that must produce two executables: the main application and an executable that is called by a separate process.

I’ve created the second file in Xcode and added a second target of type Cocoa Shell Tool. I can now build the second executable but when I try to build my project normally I get an error saying there’s two executables present:

ld: duplicate symbol _main in <path>/SecondExecutable.o and <path>/main.o

(<path> was added by me to protect the innocent and their intelectual property).

How can I configure Xcode to build both at the same time?

Answer 1

Make sure that your app source file is only in the app target, and the tool source file is only in the tool target.
