Brett,

I’m afraid that I’m in the dark on this one too, hopefully someone else will have some more knowledge. What version of OS X are you running? If you are using Snow Leopard the static analyzer tool is now built into Xcode, so that may fix/bypass your problem completely.

Here’s a link: http://developer.apple.com/mac/library/featuredarticles/StaticAnalysis/index.html

Best,
Michael

I forgot to mention the command I am using is

scan-build -k -V xcodebuild -sdk iphonesimulator3.1 -configuration Debug

I am also having the “scan-build: Removing directory because it contains no reports.” problem. I have tried changing the project properties to “iphone simulator 3.1″ and “no code signing”. I have moved the binaries to /usr/local/bin. I did a clean in Xcode. I’ve tried “–use-cc=/usr/bin/gcc-4.2″ (this created another error about an invalid base, and I noticed that /usr/bin/gcc was already pointing to /usr/bin/gcc-4.2). I am using version 2.31. I am not seeing any errors related to SSE in the console. Any other suggestions?

That worked for me on the first shot, thanks Brian. Beautiful tool. Great time saver.

I just found my own answer:

THIS WORKED:

scan-build -k -V xcodebuild -configuration Debug -sdk iphonesimulator3.0

Is clang working for anyone else when analyzing a project that contains a 3.0 library such as MessageUI?

I keep getting an error “MessageUI/MessageUI.h: No such file or directory”.

It builds fine if I just do an ‘xcodebuild’ or build within xcode.

I have tried setting the basesdk for all to 2.2, and I have tried :

scan-build -k -V xcodebuild -configuration Debug -sdk iphonesimulator2.2

scan-build -k -V xcodebuild -configuration Debug -sdk iphonesimulator2.1

scan-build -k -V xcodebuild -configuration Debug

scan-build -k -V xcodebuild

Doing some searches it seems like it may have to do witht the fact that this is a 3.0 library ?

Luke,

Open Terminal.app and type ‘ls -l /’ (without the quotes).

If the tmp directory does not exist you can create it by typing ‘mkdir /tmp’ (again, without the quotes).

If the tmp directory does exist you will need to modify your permissions on it. Take a look at the man page for chmod (‘man chmod’) to see how to modify the permissions of this directory for your user. You may have to be root to modify the permissions.

Hi there,

I’ve got an error I just can not resolve whatsoever,

When I run “scan-build -k -V xcodebuild -configuration Debug -sdk iphonesimulator3.0″

Error: “scan-build: The directory ‘/tmp’ does not exist or cannot be accessed.”

Look forward to hearing from you soon.

I spoke too soon! It works. It was pilot error. In short, I did everything EXCEPT add Three20 as a direct dependency. The app compiled in spite of that, but Clang didn’t buy it.

For those experiencing similar issues, read the README that comes with Three20 and follow “Adding Three20 to your project” step by step. (I mistakenly skipped Step 4! Tsk-tsk.) Once you do that, I’m confident it will work just fine.

Has anyone been able to make Clang play nicely with Joe Hewitt’s Three20 library?

When I run Clang on Three20 itself, it’s fine. When I run Clang on my app (which uses libThree20.a), Clang (via StaticAnalyzer) reports: “libThree20.a, file is not of required architecture” … followed by a lot of undefined symbols (of course) and no output.

Clues welcome/appreciated!
