Re: Link to libs in Xcode?

When compiling a single source code file using the cc or g++ command, if your program uses routines that require linking to a library, you must do so by adding an option to the command, such as -lncurses. Being an Xcode supporter, I would like to know how to link libraries to an Xcode project. Using Xcode, I can easily compile command-line tools that don't use routines from any library. But I would find it extremely useful to be able to use, say, the ncurses library in my project. Does anybody know how to do this? If so, please explain your answer to me.

1) I think that before you ask more questions you may want to read up on the Xcode documentation, starting with

http://developer.apple.com/documentation/DeveloperTools/Conceptual/XcodeQuickTour/

and

http://developer.apple.com/documentation/DeveloperTools/Conceptual/Build_System/

The quick answer is that you add the library to your project, making sure it is a member of the targets whose source code invoke it. It's automatically added to the Frameworks & Libraries build phase for those targets. Xcode compiles the source files individually, then links them all together with the ld dynamic linker; the libraries and frameworks in that build phase are passed with the -l and -F command line parameters to ld.

2) You may wish to use the xcode-users list for questions about the development environment.
