SCAN-BUILD(1) SCAN-BUILD(1) NAME
scan-build scan-build(1) -- An utility for running the clang(1) analyzer from the command line SYNOPSIS
scan-build options build command [build options] DESCRIPTION
scan-build is a command line utility that enables a user to run the clang static analyzer over their codebase as part of performing a regu- lar build (from the command line). OPTIONS
-analyze-headers Also analyze functions in #included files. -o Target directory for HTML report files. Subdirectories will be created as needed to represent separate "runs" of the analyzer. If this option is not specified, a directory is created in /tmp (TMPDIR on Mac OS X) to store the reports. -h, --help Display the help message. -k Add a "keep on going" option to the specified build command. --keep-going This option currently supports make and xcodebuild. This is a convenience option; one can specify this behavior directly using build options. --html-title [title] Specify the title used on generated HTML pages. --html-title=[title] If not specified, a default title will be used. -plist By default the output of scan-build is a set of HTML files. This option outputs the results as a set of .plist files. --status-bugs By default, the exit status of scan-build is the same as the executed build command. Specifying this option causes the exit status of scan-build to be 1 if it found potential bugs and 0 otherwise. --use-cc [compiler path] By default, scan-build uses 'gcc' to compile and link --use-cc=[compiler path] your C and Objective-C code. Use this option to specify an alternate compiler. --use-c++ [compiler path] By default, scan-build uses 'g++' to compile and link --use-c++=[compiler path] your C++ and Objective-C++ code. Use this option to specify an alternate compiler. -v Verbose output from scan-build and the analyzer. A second and third '-v' increases verbosity. -V View analysis results in a web browser when the build --view completes. ADVANCED OPTIONS
: -constraints [model] Specify the contraint engine used by the analyzer. By default the 'range' model is used. Specifying 'basic' uses a simpler, less powerful constraint model used by checker-0.160 and earlier. -store [model] Specify the store model used by the analyzer. By default, the 'region' store model is used. 'region' specifies a field sensitive store model. Users can also specify 'basic', which is far less precise but can more quickly analyze code. 'basic' was the default store model for checker-0.221 and earlier. -no-failure-reports Do not create a 'failures' subdirectory that includes analyzer crash reports and preprocessed source files. EXAMPLES
Basic usage of scan-build is designed to be simple: just place the word "scan-build" in front of your build command: $ scan-build make $ scan-build xcodebuild In the first case scan-build analyzes the code of a project built with make and in the second case scan-build analyzes a project built using xcodebuild. It is also possible to use scan-build to analyze specific files: $ scan-build gcc -c t1.c t2.c This example causes the files t1.c and t2.c to be analyzed. AUTHORS
