[cfe-dev] Issues Running Scan-build

[Lockhart, Jonathan (lockhaja) via cfe-dev]

Alexey or Others,


So I did a fresh full build with the latest checkout of clang, LLVM, Visual Studio, and CMake. The ALL-BUILD completed successfully but unfortunately no where in the build repository do I see a command of scan-build-py. There is also no repository of build\tools\scan-build-py or build\tools\clang\tools\scan-build-py. I tried running the new version of the batch file for scan-build, located in build\bin, but unfortunately that fails, as the first line of that batch file just says perl -S scan-build, and there is nothing else in the file.

Jonathan,

as I see from your command line, you are still using an old version of scan-build. Could you check if this problem is reproducible with the newest one?
AFAIR, you can use new scan-build with your clang so it is not necessary to build clang from repository.

Alexey,


Thanks for the input, that seems to have resolved the issue. Thanks for noticing that spelling error as well. Now that you mention it, and checking the change logs, I seem to remember that being an issue before, and I link I moved to a different use environment. In any case, I now get a message about the


C:\Users\lockhaja\build\tools\clang\tools\scan-build>perl -S scan-build -v -v -o "C:\Users\lockhaja_local\Desktop" --use-analyzer=C:\Users\lockhaja\build\bin\Debug\clang.exe gcc C:\main.c

The syntax of the command is incorrect.
scan-build: Using 'C:/Users/lockhaja/build/bin/Debug/clang.exe' for static analysis
scan-build: Emitting reports for this run to 'C:/Users/lockhaja_local/Desktop/2016-01-21-1'.

'C:/Users/lockhaja/build/tools/clang/tools/scan-build/ccc-analyzer' is not recognized as an internal or external command, operable program or batch file.

scan-build: No bugs found.


I purposefully added a few bugs into the system, so I know scan-build should be locating those. Any thoughts on the "syntax of the command is incorrect" and "'C:/Users/lockhaja/build/tools/clang/tools/scan-build/ccc-analyzer' is not recognized as an internal or external command, operable program or batch file." messages that have appeared? I did check and the ccc-analyzer file appears to be complete and correct.

Hello Jonathan,

It seems like you are using an old version of scan-build. This issue should be fixed with commit 4415a4b58bd (<https://github.com/llvm-mirror/clang/commit/4415a4b58bd561d85a7dff84f62778b675a98a09>https://github.com/llvm-mirror/clang/commit/4415a4b58bd561d85a7dff84f62778b675a98a09). I suggest you to update your scan-build to the newest version and check it again.

You can also try the newest Python version of scan-build (which is located in tools/scan-build-py).

And, BTW, '--user-analyzer' option in your cmdline should be corrected to '--use-analyzer'.

Greetings,


Been a while since I emailed the list. Oddly enough I have run into an error with my scan-build installation it seems. I previously had it up and running for a project I was doing back in 2014, and that Fall was the last I touched it. I have come back to use it with the same build, nothing has changed on the machine I am using since 2014, and I am getting an error upon launching. Please see the first screenshot. I checked the scan-build perl file and it tells me that the getpwuid on line 35 is set to "Unknown." Screenshot 2 has the info from the scan-build file. Screenshot 3 has the command I am inputting and the perl command it is switching too for the command line.


Any assistance would be much appreciated and I do apologize if I am mailing the wrong list, it has been a while.
