It is still in its infancy, but establishes a baseline for things to come. The main hope is that it can find some 57 issues and have a reasonable false positive rate.</p> 58 59 <p><b>Please</b> <a href="/filing_bugs.html">file bugs</a> when you see issues of any kind so we can assess 60 where development on C++ analysis support needs to be focused.</p> 61 62 <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 63 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 64 your version of the analyzer</a>. You will then need to modify one configuration file in Xcode to enable C++ analysis support. This can 65 be done with the following steps:</p> 66 67 <ol> 68 <li>Find the clang .xcspec file: 69 <pre>$ cd /Developer/Library 70 $ find . | grep xcspec | grep Clang 71 ./Xcode/<b><SNIP></b>/Clang LLVM 1.0.xcplugin/Contents/Resources/Clang LLVM 1.0.xcspec 72 </pre></li> 73 <li>The exact location of the file may vary depending on your installation of Xcode.
