I tried using the sample CMakeLists.txt from LLVM's website, but I encounter the following error when running cmake : CMake Error at /usr/share/llvm-3.8/cmake/LLVMConfig.cmake:178 (include): include could not find load file: /usr/share/llvm/cmake/LLVMExports.cmake Call Stack (most recent call first): CMakeLists.txt:4 (find_package) CMake Error at /usr/share/llvm-3.8/cmake/LLVMConfig.cmake:181 (include): include could not find load file: /usr/share

I am getting the following error: Apple LLVM compiler 3.0 Error Error in format of file: /Users/myUserName/Library/Developer/Xcode/DerivedData/ProjectName-fkjvtdsoypoyrdcedtarbtypupor/Build/Intermediates/ProjectName.build/Debug-iphoneos/ProjectName.build/ProjectName-arc.migrate/remap Is this one of those situations where I need to manually delete some files/folders in Finder and then try it again? I just deleted everything in the "Build"

I need to deprecate a single method in objective-c protocol. On normal class/instance methods I add __attribute__ ((deprecated)); after declaration. It seems, that it does not work on protocol methods. If I mark them deprecated and use them somewhere the project compiles OK, without expected deprecation warning. Is it a flaw in Apple LLVM 3.1, or am I doing something wrong? Although the answers here provide some very good information, they are outdated. Starting with Xcode 5.0 and LLVM 5.0 it looks like deprecation warnings for Objective-C protocol methods are recognized. When implementing the

I've installed Qt SDK with Qt Creator on my Windows 7. LLVM & Clang installed as well. CMake was already installed. Afterwards added Clang as a compiler into: Tools -> Options... -> Build & Run -> Compilers Then I've created Clang kit. However while creating new project (simple console application) I've no ability to choose Clang kit. There are only autodetected MSVC kits. Maybe the problem is that "Qt version" in Clang kit is empty. But where to get qmake for it? You should also have an appropriate compiled Qt library with Clang. There is no Clang build of Qt for Windows in the download page.

Currently, I build programs by invoking G++, but when I check the version via $ g++ -v , I get: gcc version 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.11.00) What's going on? Am I using G++? GCC? LLVM? I don't even know. Are they the same thing? So now I'm trying to build and download GCC 4.7 via gnu.org , but I have no idea what any of the guides are talking about. I've never seen so

Basically I want to have an LLVM IR dumps before and after each optimization pass, also it can be useful to have all dumps of AST from clang and all phases of code generation (backend phases, Selection DAG, ISEL-SDNode, register allocation, MCInsts). I was able to find only the clang's -ccc-print-phases , but it will only print high-level phases names, e.g. preprocess-compile-assemble-link; but no any dump of

When I upgraded my OS to 10.8 Mountain Lion (Edit: From 10.7), I was forced to upgrade Xcode. In upgrading Xcode, I lost the ability to compile my c++ project for deployment on 10.6 systems as I get the following error. clang: error: invalid deployment target for -stdlib=libc++ (requires Mac OS X 10.7 or later) It appears that Apple is trying to force people to upgrade by not allowing developers to support Snow Leopard. This makes me angry.

How can I accomplish this? 回答1: Here's some working code based on Nathan Howell's: #include #include #include #include #include #include #include #include #include #include using namespace std; using namespace llvm; int main() { InitializeNativeTarget(); llvm_start_multithreaded();
