I am part of a project with multiple developers. The project contains multiple targets. VERY often, files are committed to the Xcode project repository with some targets not-included (careless programmers). So whenever i do a 'svn up', and run the app, my program crashes. I then have to look through all those files and see which one was committed with the missing target, then add the target, and recommit the file to the repository (for that careless programmer)
Is there some way through a script to either automatically add all .m to a particular target?
OR
list all the files that are missing for a particular target?
I have looked at Add files to an XCode project from a script for reference already.
My answer on this other thread shows you how to see all files that are not part of a target:
https://stackoverflow.com/a/12867723/591586
I did as Paul suggested and wrote a python script that inspects the .pbxproj and lists all the files and the targets they are included in.
You could easily modify that script so that it highlights the files that are not included in specific targets.

This question has been asked before, but neither did that question got an answer.
As far as I know, XCode does not have any build in support for comparing targets. However, the project is nothing more than an set of XML files... very detailed XML files though.. but still XML.
What you could do (this is not something I recommend though) is read through the XML files of the project and try to understand how they are build.
I know this is not the answer you are looking for, but it might be a workaround.
Update
I read though project.pbxproj of a test project with two targets, and it seems as if the project is build up into references. Which is smart since one wouldn't have a huge file if you have many targets. However, it does mean that its really hard to read.

I know this might sound a bit strange but I'd need to generate a xcodeproj automatically.
Basically scanning the filesystem and adding certain files to the project and to a specific target.
The main reason behind this, is that I work in an zero IDE environment. Thus, we have our own build system and source files are added and removed all the time.
I could use "create folder references for any added folders". However, xcode won't ever parse source files if they aren't part of any target. So, no symbols, no code completion...
To me, my only option would be to "auto-update" my xcodeproj with a script...
Thanks in advance for your inputs!
Cmake is one option (see this related question) and there's also Scons which I think can generate Xcode projects. There's also Qt's qmake which can generate the project files, but this is probably overkill unless you're using full Qt.
You can either user AppleScript (or anything OSA-compatible) to automate the process of creating the project in Xcode itself, or you could look at CMake, which is able to generate Xcode project files.
I'm new to XCode and I find the file management a huge pain. In most IDEs, you can simply have the project source tree reference a directory structure on disk. This makes it easy to add new files to your project - you simply put them on disk, and they will get compiled automatically.
With XCode, it appears I have to both create the file and separately add it to the project (or be forced to manipulate the filesystem through the UI). But this means that sharing the .xcodeproj through source control is fraught with problems - often, we'll get merge conflicts on the xcodeproj file - and when we don't, we often get linker errors, because during the merge some of the files that were listed in the project get excised. So I have to go and re-add them to the project file until I can get it to compile, and then re-check in the project file.
I'm sure I must be missing something here. I tried using 'reference folders' but the code in them doesn't seem to get compiled. It seems insane to build an IDE that forces everyone to modify a single shared file whenever adding or removing files to a project.
Other answers notwithstanding, this is absolutely a departure from other IDEs, and a major nuisance. There's no good solution I know of.
The one trick I use a lot to make it a little more bearable — especially with resource directories with lots of files in them — is:
select a directory in the project tree,
hit the delete key,
choose "Remove References Only", then
drag the directory into the project to re-add it.
This clobbers any manual reordering of files, but it does at least make syncing an O(1) operation, instead of being O(n) in the number of files changed.
I'm intrigued which IDEs you're using that automatically compile everything in a directory, as no IDE I've ever used does that (at least for C++). I think it's pretty standard to have a project file containing a list of all the files. Often you may want to only include certain files for different targets, have per-file compiler settings, etc.
Anyway, given that that's how it does work, you really shouldn't have too many problems from merge conflicts. The best advice would be commit early and often so that you don't get out of step with other people's changes. Merely adding files to the project shouldn't result in a conflict unless they happen to be added at exactly the same point in the project tree. We've been using Xcode in our team for years and we very rarely get conflicts: only if someone has restructured the project.
Fortunately, because the Xcode file format is text, it's generally quite easy to resolve conflicts when they occur, unlike the Bad Old Days of Codewarrior with it's binary format.
I am building a cross platform product and one of the requirements is across windows(win32,AMD64 and IA61). The product as is relatively simple CLI but we have a separate build team who checks out the code from CVS and build in separate build environments. I am able to build succesfully(using Visual C++ 2005) in one platform(AMD machine). But once I check in the code, check out the build fails.
The cause of the build failure is because the include library paths are wrongly specified in the property sheets. Specifically the output file folder under the Linker in property pages are specified wrongly. So these libraries get built in a different folder from where the other projects are expecting them.
However along with the source I check in the .sln files (and later .vcproj files) also everytime. Morover if I open the .sln file in the folder where the build is not succeeding, there is no difference between the one where I could succesfully build(pre check in). In fact using windiff I could not see any difference between the two build folders (except some .ncb and cvs log files).
So any idea what is going on? Where does VC++ 2005 take the include directories take the output folder path from if not from .sln? Is CVS somehow interfering with the process? Anything else I could try out.
Thanks in advance.
Just to update the problem was resolved. The root cause is the .vcproj files were not getting checked in CVS!! This is where the individual project settings were stored(I was under the impression that this is done in .sln files).
I think the problem can be that after you have changed the settings in one build configuration (for example x86-Release) but forgotten to change them for another configuration (for example ia64-Debug), and when configuration changes, you have this problem.
Another thing that I would check on your place is project dependencies. If those are set in the right way VS will look for project output exactly where it is outputted, even when you change the output folder.
Do you have any binary files checked in as ASCII?
The round trip to and from CVS can corrupt binary files that are incorrectly marked as ASCII because CVS performs character processing on ASCII files (e.g. to give you the correct end of line codes for your OS). Corruption can occur even in an all Windows environment.
See the Binary section in the CVS FAQ for more information.
I am using Xcode as part of my build for OS X, but since it is not the only IDE used, files may be added from the file system directly.
As far as I can tell, there are two ways of adding folders:
Folder reference picks up all the changes on the file system but does not register any of the files as sources.
Recursive copy allows for the files to be built but I need to constantly maintain the file structure
I am wondering if there was a way to setup Xcode to build all of the files that are a part of the folder reference or failing that, if there is a quick script to automagically fix file system discrepancies.
I came up with proof-of-concept solution that works, but will require some work to use in production. Basically, I set up a new "External Target", which compiles all source files in a given directory into a static library. Then the static library is linked into the Main Application.
In detail:
Create a directory (lets call it 'Code') inside your project directory and put some source code in it.
Create a Makefile in the Code directory to compile the source into a static library. Mine looks like this.*****
Create an External Target (lets call it 'ExternalCode') and point it to the Code directory where your source and Makefile reside.
Build the ExternalCode and create a reference to the compiled static library (ExternalCode.a) in the Products area of your project. Get Info on the reference and change the Path Type to "Relative to Built Product".
Make sure ExternalCode.a is in the "Link With Binary Libraries" section of your main target.
Add the ExternalCode target as a dependency of your main target
Add the Code directory to your "User Header Search Paths" of your main target.
Now when you drop some source files into 'Code', Xcode should recompile everything. I created a demo project as a proof of concept. To see it work in, copy B.h/m from the 'tmp' directory into the 'Codes' directory.
*Caveats: The Makefile I provided is oversimplified. If you want to use it in a real project, you'll need to spend some time getting all the build flags correct. You'll have to decide whether it's worth it to manually manage the build process instead of letting Xcode handle most of the details for you. And watch out for paths with whitespace in them; Make does not handle them very well.
Xcode's AppleScript dictionary has the nouns and verbs required to do these tasks. Assuming your other IDE's build scripts know what files are added/deleted, you could write very simple AppleScripts to act as the glue. For example a script could take a parameter specifying a file to add to the current open project in Xcode. Another script could take a parameter to remove a file from the current project. Then your other IDE could just call these scripts like any other command line tool in your build script.
I'm not aware of any built-in functionality to accomplish this. If you need it to be automatic, your best option may be to write a Folder Action AppleScript and attach it to your project folder.
In all likelihood it would be a rather difficult (and probably fairly brittle) solution, though.
It's not pretty, and I think it only solves half your problem but... If you recursively copy, then quit xcode. Then you delete the folders, and replace them with simlinks to the original folders, you at least have files that are seen as code, and they are in the same files as the other IDE is looking at... You still will need to manually add and remove files.
I sort of doubt that there's a better way to do this without some form of scripting (like folder actions) because xcode allows you to have multiple targets in one project, so it's not going to know that you want to automatically include all of the files in any particular target. So, you're going to have to manually add each file to the current target each time anyway...
One way to import another file from add/existing file:
and set your customization for new file that added .

I am trying to set up Xcode for a project which contains multiple executables and static libraries. I have created multiple targets and set up the linking and dependencies, and initially everything works great. The catch...
This is an existing project which already has Visual Studio and Makefile builds. Those builds put the libraries in a lib/Debug directory and the executables in bin/Debug. So in Xcode I changed the Build Products Path to "lib" and "bin" respectively (so we can use one set of documentation for all of the platforms). This puts the compiled targets in the right place, but completely breaks both the linking (Library not found) and the dependencies.
I can fix the linking by adding $(SRCROOT)/lib/Debug to the Library Search Paths for each executable (but it feels like Xcode should be able to figure this out on its own, which makes me think I'm doing something wrong).
But — I can't figure out how to get the dependencies working again. If I change a library source file, the library will rebuild but not the dependent executables. If I force a build of the executable Xcode returns success without doing anything; it thinks the target is up to date. If I clean the target and then rebuild it works.
So, any ideas here? Is Xcode being fundamentally stupid in this regard, or is it me (I'm leaning toward the latter)?
Update: I've posted a sample project to demonstrate the issue at http://share.industriousone.com/XcodeDepsIssue.zip. Build it once, then modify MyStaticLib.c and build it again. The executable will not relink (and it should). Many thanks for any help on this one.
starkos, thanks for publishing your conclusion. It validated my experience as well. This situation really screwed me, so it was nice to know I wasn't just missing something.
I did however discover a workaround that avoids creating multiple projects or keeping the library and its dependent in the same directory. It is a hack, but it does work here.
I know it's a bit late but better than never.
For the dependency library, add a "Copy Files Build Phase", with Absolute Path as the destination, and the path text field should be the directory where the DEPENDENT target lives. Then click on Products, find the dependency library (will end with .a), and drag it into the "Copy Files Build Phase." If you now build, this will put the library into its own directory like before and THEN also copy it into the dependent's target directory.
For the dependent, you can now remove the dependency's output directory from the Library Search Paths. This will cause it to find the library copy. If you do this, the dependent will indeed be relinked each time the dependency .a is relinked.
The negatives are, of course, the extra time for the copy, and the necessity to specify (in the Copy phase) the target directory for each dependent of your library. Beats the hell out of the alternatives though....
Xcode doesn't automatically set up dependencies based on use of build products; you have to set up explicit target dependencies yourself.
Project > Edit Target Settings, General tab, + button, add any targets that are prerequisites to building the selected target. That should get you going again.
I've researched this some more and the answer is no, Xcode 3.x doesn't track dependencies between targets that live in different directories. You can work around it by giving each library its own project, and adding each of those to a master project. Or you can keep all of your targets in one directory. Pick your poison.
Here is my solution for this weird behavior in xcode 4.3.1. You have to add build pre-action in scheme:
rm -f ${BUILT_PRODUCTS_DIR}/${EXECUTABLE_PATH}
and choose which build settings to use for this script. Each time before build, target executable will be removed and rebuild completely. It helped for me, and i hope it helps you.
NOTE: Have tried to put this script in project build phase, and result was negative - debugger could not connect process to start debugging.
Good luck!
OK, it would help to have the text of the Linking... build line that's failing. But a couple of things:
1) You shouldn't be linking to anything in $(SRCROOT). That's your project sources. The two places to find things to link are $(SYMROOT) (the Build Products directory) or $(DSTROOT) (the Installed Products directory).
One thing you could do is to have a common Build Directory, then use 'xcodebuild install' action to install the products in the Installation Directory. The other is to use a Copy Files build phase to copy them after building, so you can link against them in $(SYMROOT) but still have them where your Windows compatriots expect them.
THere is probably a way to set up the per-target build products directories correctly, but I'd really have to see the project itself to figure it out.
