I have a need to look at the files Xcode will compile before the preprocessor gets a stab at them. In short, I need to stick a preprocessor in front of the preprocessor.
All the Google searching has netted me nada when it comes to details on how to run the default Xcode build process for C-based files after modifying the build rule for "C source files". Xcode seems to call a process (shell script? voodoo chant?) called "CompileC" but I cannot find it to call it myself after I'm done with the source file.
Any ideas? For the curious, I need to modify certain macros in very specific situations (depending on the source file's name or the build date, for example). And there doesn't appear to be a clever way to do: #ifdef filename="bobsyeruncle.m"
It looks like a build-rule script would work: http://developer.apple.com/mac/library/documentation/DeveloperTools/Conceptual/XcodeBuildSystem/200-Build_Phases/bs_build_phases.html#//apple_ref/doc/uid/TP40002690-CJAEACAD

I'm currently trying to make splint available as an external tool in Visual Studio 2010.
It has problems with finding all includes for the file, since it seems that the INCLUDE variable is only set at build time and I haven't found any other possibility to extract the include files in any way.
My question: Would there be any way to extract the IncludeDir field from the current file's project's Properties page, ideally with the VC++'s AdditionalIncludeDirectories?
Note also that AdditionalIncludeDirectories is per file, as it can be changed for individual source files as well as on the project level, and if it contains macros it can evaluate differently for each source file too!
I'm not familiar with driving the MSBuild objects via the API, but that's used by the IDE. Whether that way or by simply running MSBuild.exe, you need to get it to figure out all the properties, conditions, etc. and then tell you the result. If everything is well behaved, you could create a target that also uses the ClCompile item array and emits the %(AdditionalIncludeDirectories) metadata somehow such as writing it to a file or passing it to your other tool somehow. That's what's used to generate the /I parameters to CL, and you can get the same values.
If things are not well behaved in that necessary values are changed during the detailed build process, you would need to get the same prelims done just like the ClCompile target normally does, too. Or just override ClCompile with your own (last definition of a target is used) so it certainly is in the same context.
Either way, there are places where build script files can be automatically included into all projects, so you can add your stuff there or use a command argument (I think) to MSBuild to add another Include.

I am trying to compile a bash project into a distributable binary. I tried shc, and it worked, except all my source statements were broken. I have numerous source statements to keep the code base cleaner, but they are broken when compiled with shc. How can I compile down my bash project so that instead of having a bunch of .sh files, the end user can just have one single file?
Shc is an obfuscator, not a compiler. At the end of the day, it still invokes /bin/sh or whatever, and feeds it your original script. It has not a slightest idea what your script actually does. If it needs an additional file to source, you have to supply it at an appropriate location.
You may want to investigate things like SHAR. Build anarchive, then compile it with shc if you want.
It sounds like all you're missing is a facility to expand all your source statements. That should be fairly easy to write if your codebase is fairly consistent in its use of those statements: just write a script to expand them inline and away you go.
Alternatively, just put all your scripts into a single Zip file or tarball and tell the user to extract the contents of that one file, or if even that is too much I'm sure you can imagine a way to encode the zipped contents of all the non-main files into a giant comment at the bottom of the main file, and have it extract what it needs before proceeding.
Or, you know, use the appropriate installer for your system. Build an RPM for RHEL or a Debian package or a Windows MSI or whatever....
I am trying to compile the following software so that I can step through and debug it. I am only a novice programmer and I am trying to understand how this whole makefile business works with Fortran. I know that there is a ton of literature on makefiles but I just need to insert a simple debug flag and I think if someone provided me with the answer to this question that would be the best way for me to learn.
So the program I am trying to compile, TINKER, is actually made up of several packages, located at http://dasher.wustl.edu/tinkerwiki/index.php/Main_Page. I would like to compile and debug JUST ONE specific executable, "analyze". I contacted the developer and received the following reply but I am still stuck...
Since TINKER has lots of small source code files, what we do is
compile each of the small files to an object file using the "-c" flag.
Then we put all of these object code files (ie, the ".o" files) into
an object library. Finally, we link each of the TINKER top level
programs, such as "analyze", against the object library. There is a
Makefile supplied with TINKER that does this. We also supply
individual scripts called "compile.make", "library.make" and
"link.make" for various CPU/compiler combinations that can be run in
order to perform the steps I describe above. To build a "debuggable"
executable, you just need to include the appropriate debug flags
(usually "-g") as part of the compile and link stages.
I am currently running OSX 10.6.8. If someone could show me which folders I cd into, what commands I enter that would be so great!
Thanks!
My follow up question (once I can figure out how to answer the above via command line will concern how to import the same procedure but using the Photran IDE - http://wiki.eclipse.org/PTP/photran/documentation/photran5#Starting_a_Project_with_a_Hand-Written_Makefile)
The directions are at http://dasher.wustl.edu/tinkerwiki/index.php/Main_Page#Installing_TINKER_on_your_Computer
Maybe out of date? g77 is obsolete -- it would be better to use gfortran.
The key steps: "The first step in building TINKER using the script files is to run the appropriate compile.make script for your operating system and compiler version. Next you must use a library.make script to create an archive of object code modules. Finally, run a link.make script to produce the complete set of TINKER executables. The executables can be renamed and moved to wherever you like by editing and running the ‘‘rename’’ script."
So cd to the directory for the Mac -- based on "we also provide machine-specific directories with three separate shell scripts to compile the source, build an object library, and link binary executables." Then run the command scripts. Probably ./compile.make. Look around for the directories ... you can probably figure it out from the names. Or search for the file "compile.make".
Or find someone local to you who knows more about programming.
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 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 .
