Unfortunately, something about the parts I added broke the build in a way I just cannot figure out. tl;dr ld asks for a library containing a _wordexp symbol for iOS simulator, and I have absolutely no clue where it is, if it exists Compilation consistently fails for me when the compiler is attempting to link the address sanitizer dylib for iOS Simulator. Reproduction steps (OS X only as far as I know, don't have *nix systems handy): install homebrew if it isn't

gcc is symbolically linked to llvm-gcc on Mac OS X Lion. prosseek ~> ls -alF /usr/bin/gcc lrwxr-xr-x 1 root wheel 12 Nov 12 14:39 /usr/bin/gcc@ -> llvm-gcc-4.2 How can I setup to use gcc-4.2 when gcc is called? As of Xcode 4.2 in Lion, Apple no longer ships its previous version of gcc-4.2 , which was in Xcode 4.1 and earlier versions. It now only ships llvm-gcc (gcc front-end with llvm code backend) and clang (clang front-end with llvm backend). While it is possible to install legacy versions of vanilla GNU gcc-4.2 from other sources, like MacPorts, (and without disturbing /usr/bin ), Apple

And looking into /usr/bin/gcc it does not appear to link to Clang. Any suggestions on how to fix my Clang errors and get openmp to compile? 回答1: The

I installed the LLVM 5.0.0 binaries, the Ninja build environment, the VS 2017 Tools and CMake 3.9.3. The final aim is to be able to compile C and C++ applications for Windows using VS Code with the CMake integration as "IDE" and Clang with LLD as compiler and linker. The compilation and execution of a simple program worked perfectly fine ( screenshot of the respective terminal history ). Clang automatically

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();

I also tried UIKit.framework, but I am getting Fatal Error: 'UIKit/UIKit.h' not found with both. Any suggestions? Thanks 回答1: Compiling for iOS without using Xcode is not easy. In your case, you're trying to use an iOS framework but you're using neither the iOS toolchain's compiler nor the iOS SDK. If you look at the compile transcript for an Xcode project you'll see some of the flags that are necessary. Things you'll need include: xcrun

I'm trying to write a compiler detection header to be able to include in the application information on which compiler was used and which version. This is part of the code I'm using: /* GNU C Compiler Detection */ #elif defined __GNUC__ #ifdef __MINGW32__ #define COMPILER "MinGW GCC %d.%d.%d" #else #define COMPILER "GCC %d.%d.%d" #endif #define COMP_VERSION __GNUC__, __GNUC_MINOR__, __GNUC_PATCHLEVEL__ #endif Which could be used like this: printf(" Compiled using " COMPILER "\n", COMP_VERSION); Is there

I am following this website http://llvm.org/docs/HowToCrossCompileLLVM.html using this command to configure cmake: I am using the following command and getting the following errors (see below). Any idea what is wrong?
