[cfe-dev] Help required to use clang analyzer

[Arnab Kumar Biswas via cfe-dev]

Hi,
I want to thank you for replying my question.

Actually I want to use the taint checker or modify it.

clang -cc1 -analyze -analyzer-checker=alpha.security.taint.TaintPropagation test.c

But it produced the same error as I mentioned in my last question.

Please tell me the procedure to use a particular checker. I was following the description as given in http://clang-developers.42468.n3.nabble.com/Purpose-of-GenericTaintChecker-td4051900.html and http://clang-analyzer.llvm.org/checker_dev_manual.html.

I have tested the command "scan-build clang test.c" and it is working correctly. But I am not really interested to create the a.out and more interested to do the static analysis and get some kind of report.

Hi,

Using -cc1 disables the clang Driver. The Driver is responsible for gcc
compatibility, which, apart from being able to translate gcc flags to
clang flags, adds support for finding system headers in places where gcc
usually looks for them. There are other drivers, such as clang-cl which
turns clang into a drop-in replacement for the Visual Studio's cl.exe.

Running without the driver is not recommended for everyday use, only for
development of clang itself.

If you want to run the Static Analyzer on a single file, you can do

     clang --analyze test.c

But even better, you should use the scan-build tool to analyze the
entire project, for example:

     scan-build clang test.c

or

     scan-build gcc test.c

or

     scan-build make -j4

etc. See https://clang-analyzer.llvm.org/scan-build.html for more details.
