Mac Forum / Programming / Mac Programming / October 2006Multiple executables with XCode
Hi! I would like to have several executables within the same project. Is this possible? Two seperate projects with a common library is not too handy since the purpose of the executables would be to test the common code in different contexts. Raphael Yes, you create a new project and then create multiple targets, 1 for each exe and for the library. (You can pick when you create the target what type it is). Then add the files to the project assiging them to correct project. By putting them in the same project the .h files needed by the exe's from the library will automaticaly be found. Also you can specify for each project what other project it depends on. That is your EXE's will depend on the library. That way if the lib code changes when you rebuild your exe it will do the lib first. See the help in XCode. It discusses the tradeoffs of doing this as separate projects or one big project with multiple targets. --jim > Hi! > [quoted text clipped - 4 lines] > > Raphael In article <eh2mro$dd0$1@news.lrz-muenchen.de>, Raphael Mameghani <contact_me_via_my_homepage@raphael.mameghani.de> wrote: > Hi! > [quoted text clipped - 4 lines] > > Raphael Sure. Each executable is a separate target, and an umbrella target that lists all the others as dependencies, but does nothing itself. Build the umbrella, and it builds all the other targets. I usually add a Unit Test target to my projects, that builds the application, then links to the application as if it were a dynamic library, so the unit test can create internal objects of the executable without having to include the application's .m files.

It's not only possible, it's very well documented in the Xcode help. What part of the process were you having trouble with? sherm--  SignatureWeb Hosting by West Virginians, for West Virginians: http://wv-www.net Cocoa programming in Perl: http://camelbones.sourceforge.net > I would like to have several executables within the same project.

A target is a set of instructions for generating a *build product* of some sort, typically an executable, library, or plug-in bundle. > Two seperate projects with a common library is not too handy since the > purpose of the executables would be to test the common code in > different contexts. You may also want to look into Xcode's unit testing infrastructure. It will allow you to write tests for your framework that specify its behavior and that can be run every time you press command-B to build your project. -- Chris > [the solution] Thank you - now I understand the concept of targets. Sorry for my stupid question but this is the first time I use a development environment such as XCode (apart from Turbo Pascal;-) ).

XCode is a very complicated environment and lots of people discuss it here. I've seen far more stupid questions. Simon.

"Stupid" in such a sense that I easily could have figured out the solution by myself;-) Raphael On 17/10/2006, Raphael Mameghani wrote in message <eh2mro$dd0$1@news.lrz- muenchen.de>: > I would like to have several executables within the same project. Is > this possible? One executable is one target. Take a look at the examples included as part of the Developer Tools. /Developer/Examples/OpenGL/GLUT/GLUTExamples.xcodeproj/ is a good example.
