Hi,
I had same problem, i.e. got error like:

scan-build: Removing directory '/var/folders/x2/x2PXNw6pE7O8Zr7cBMzy1U+++TI/-Tmp-/scan-build-2009-04-10-1' because it contains no reports.

After investigating it, in my case, this was happening because of either one of two reasons:

Reason 1 - I had a compilation error in my code. When I fixed the compilation error then it worked.

Reason 2 - The scan-build analysed my code and I had no actual errors.

So in my case, while my code compiled and while I had memory leaks in my code, the analyser worked and I got the web page pop up with the results. Otherwise I got something like the error listed above in the terminal window.

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 ?

it s showing same : Code Signing Identity 'iPhone Developer' does not match any code-signing certificate in your keychain. Once added to the keychain, touch a file or clean the project to continue. i did same as u explained above.please help me to test

I had the same problem I added the extra parameters after xcodebuild:
scan-build -k -V xcodebuild -configuration Debug -sdk iphonesimulator2.1

Also check on your Project info > Configurations tab (at the very bottom) that you are set to Debug in the "Command-line builds use:" option

Nice article

Thanks a lot for this posting. It helped a lot getting clang to work.

Yes I think that is my problem clang is not analyzing those files.
This is a pain as I am using some C++ mixed with objective C

benoitcerrina — Sun, 12 Apr 2009 23:44:55 -0000

Do you know if clang works on objectiveC++
Most of my source files are .mm that may be the problem?

Yes it is in my build path.
Moreover I did add some errors (in particular the exact one you suggested) and it didn't change the result. Nothing is reported and the directory is removed.

I also have to say that on toy projects it work it is just in my real project where it doesn't

Ahh cool. Good tip :)

Is scan-build in your path? I've had problems in the past when running it by specifying relative paths.

Otherwise, you can try introducing a bug into your application.

E.g. `NSNumber *number = [[NSNumber alloc] initWithInt:0];` and don't `release` it. That should introduce 2 bugs: a dead initialization, and a memory leak.

unfortunately when I run this on my project I receive no report and the last line is
scan-build: Removing directory '/var/folders/x2/x2PXNw6pE7O8Zr7cBMzy1U+++TI/-Tmp-/scan-build-2009-04-10-1' because it contains no reports.
can someone give me an example of the type of errors clang finds? I am really surprised that it didn't find any in my project but I'd like to try to add explicitly errors to verify that it works

Or use scan-build -k xcodebuild -configuration Debug -sdk iphonesimulator2.2 rather than changing the project :)

That message indicates that the static analyzer could not detect any problems with your code. Perhaps try introducing a bug in your application. E.g. `NSNumber *number = [[NSNumber alloc] initWithInt:0];` and don't `release` it. That should introduce 2 bugs: a dead initialization, and a memory leak.
