<html><head><meta http-equiv="Content-Type" content="text/html charset=us-ascii"></head><body style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space;">Hi,<div><br></div><div>After watching Chandler Carruth's <a href="http://channel9.msdn.com/Events/GoingNative/2013/The-Care-and-Feeding-of-C-s-Dragons">http://channel9.msdn.com/Events/GoingNative/2013/The-Care-and-Feeding-of-C-s-Dragons</a> I decided to try the format and modernize examples in the middle of his presentation. After installing the latest LLVM suite, all examples without #include files work fine, both in clang-format and clang-modernize. Very impressive.</div><div><br></div><div>Using the native (Apple, Xcode) toolchain, I can cmake, make and run the example programs in a build directory directly under the source directory, e,g. clang-tools/vector/build under clang-tools/vector which contains vector.cpp and CMakeLists.txt.</div><div><br></div><div>But clang-modernize will fail *if* it contains a template based #include, e.g. Chandler's loop-convert example based on a small vector<int> loop.</div><div>Somehow I can't figure out how to specify the right flags for the compiler/linker in cmakelist.txt.</div><div><br></div><div>Any pointers appreciated!</div><div><br></div><div>Thanks,</div><div><div apple-content-edited="true">
