README.txt

The enclosed config.xml file will instruct Jenkins to check out and build llvm + clang, archiving the resulting clang binary.

The configuration will build daily and will retain builds for 5 days.

To add it to your Jenkins install, just copy the config.xml file to e.g.:

jobs/Clang/config.xml

Then "reload configuration" in Jenkins, or stop and start Jenkins to reload it implicitly.

Depending on your use case, you may want to alter the configuration so it builds a debug version of clang. For more information about building clang and the options for controlling optimization, see here:

http://clang.llvm.org/get_started.html#build

The archived clang will have its execute bit set (this is required due to a bug in Jenkins, which will hopefully be fixed at somepoint. See: https://issues.jenkins-ci.org/browse/JENKINS-9741). Also, a file will be created

${JENKINS_HOME}/StableClangPath.txt

which can be injected into the build environment of another job. It sets the property STABLE_CLANG_PATH to the full path of the just archived clang executable, which in turn can be used to run scan-build with the latest clang as part of a job. 

Enjoy!
