< li > Lots of bug fixes and improvements to analyzer precision (fewer false positives, possibly more bugs found).
< li > Introductory analysis support for C++ and Objective-C++.
< / ul >
< p > This build contains basic support for C++ and Objective-C++ that is ready to be tried out
by general users. It is still in its infancy, but establishes a baseline for things to come. The main hope is that it can find some
issues and have a reasonable false positive rate.< / p >
< p > < b > Please< / b > < a href = "/filing_bugs.html" > file bugs< / a > when you see issues of any kind so we can assess
where development on C++ analysis support needs to be focused.< / p >
< p > To try out C++ analysis support, it should work out of the box using < tt > scan-build< / tt > . If you are using this checker build
as a replacement to the analyzer bundled with Xcode, first use the < tt > set-xcode-analyzer< / tt > script to < a href = "/xcode.html" > change Xcode to use
your version of the analyzer< / a > . You will then need to modify one configuration file in Xcode to enable C++ analysis support. This can
be done with the following steps:< / p >
< ol >
< li > Find the clang .xcspec file:
< pre > $ cd /Developer/Library
$ find . | grep xcspec | grep Clang
./Xcode/< b > < SNIP> < / b > /Clang LLVM 1.0.xcplugin/Contents/Resources/Clang LLVM 1.0.xcspec
< / pre > < / li >
< li > The exact location of the file may vary depending on your installation of Xcode. Edit that file, and look for the string " --analyze" :
< pre >
SourceFileOption = "--analyze";
FileTypes = (
"sourcecode.c.c",
"sourcecode.c.objc",
);
...
< / pre >
Change the " FileTypes" entry to:
< pre >
FileTypes = (
"sourcecode.c.c",
"sourcecode.c.objc",
"sourcecode.cpp.cpp",
"sourcecode.cpp.objcpp",
);
