- We do indeed have a lot of unnecessary includes around in llvm (or pretty much any other C++ project for that matter). - I want faster builds. - The only way to reliably fight this is indeed automatic tools. - Having the right amount of includes also has documentation value and ideally let's you understand the structure of your project. - However relying on transitive includes works contrary

Hi, I might just be doing something stupid, but when I do $ cmake -DCMAKE_INSTALL_PREFIX=/usr/local/llvm-2.8 -DCMAKE_BUILD_TYPE=Release .. $ sudo make install I don't get the expected headers in /usr/local/llvm-2.8/include/llvm It is simply an empty directory. What am I doing wrong? This is on Mac OS X, CMake 2.8+ Kind regards, Samuel
