clang

问题 This question is about using C-Functions from a MinGW dll in a VC++ project, which fails with the following error: Run-Time Check Failure #0 . I successfully build clang and more importantly libclang using MinGW (to have a libclang.dll that uses the MinGW standard library). My application previously used a VC++-build of libclang, that I now want to exchange with the MinGW build. To do that, I created a def-file and afterwards an import library from the MinGW dll file: dlltool -z libclang.def

问题 I am trying to compile a Shared Object (.so) with Visual Studio 2015 RC. I am linking against the Opus Codec libs in my stdafx.h: #pragma comment(lib, "..\\..\\opus-1.1-beta\\win32\\VS2010\\Win32\\Debug\\celt.lib") #pragma comment(lib, "..\\..\\opus-1.1-beta\\win32\\VS2010\\Win32\\Debug\\opus.lib") #pragma comment(lib, "..\\..\\opus-1.1-beta\\win32\\VS2010\\Win32\\Debug\\silk_common.lib") #pragma comment(lib, "..\\..\\opus-1.1-beta\\win32\\VS2010\\Win32\\Debug\\silk_fixed.lib") #pragma

问题 The references I know are here: http://clang.llvm.org/docs/ClangCommandLineReference.html http://clang.llvm.org/docs/DiagnosticsReference.html but I can't find flags like -msse4.1,so are there complete list of supported flags on clang.llvm.org,or we need external documentation? 来源： https://stackoverflow.com/questions/55348280/where-is-the-complete-documentation-of-clang-flags

问题 I'm attempting to set-up CI for our Xcode cross-compiles. The cross-compiles test both ARMv7 and ARMv8. Things look good except when it comes time to link for ARMv8: clang++ -DNDEBUG -g2 -O3 -fPIC -pipe -Wall -miphoneos-version-min=7 -arch arm64 \ -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS10.2.sdk \ -stdlib=libc++ -c cryptlib.cpp clang++ -DNDEBUG -g2 -O3 -fPIC -pipe -Wall -miphoneos-version-min=7 -arch arm64 \ -isysroot

问题 I'm trying to compile a simple app to test a few libraries I might be using in the future. Because of some problems I had with msvc I tried Clang, which made a strange error I got disappear. The problem I have now is that the libraries I want to test use OpenMP. They import it using the FindOpenMP module CMake privides. However the module doesn't find it with Clang. cmake_minimum_required(VERSION 3.14.0) project(blaze-test VERSION 0.1.0) set(CMAKE_CXX_STANDARD 14) set(CMAKE_CXX_STANDARD

问题 I know that Clang and GCC are more or less compatible C/C++ compilers as long as one takes care of things like architecture flags, predefines and linking the right libraries. Creating libraries with one compiler and linking them with objects created by the other is actually pretty easy (at least on x86). Here is a little test project doing exactly that: https://gitlab.com/higaski/Interoperability I was wondering however if Link Time Optimization (LTO) could somehow work across compilers? I

问题 i got a problem about how to write a clang plugin that will change the code. i want inject some code to the program,just like this:enter code here //the original code //the filename is user_code.cpp int f1(){ return 1; } int f2(){ return 2; } int f3(){ return 3; } int main(){ for(int i=0;i<1000;i++)f1(); for(int i=0;i<10000;i++)f2(); for(int i=0;i<100000;i++)f3(); return 0; } //the injected code int function_counter[3]; int f1(){ function_counter[0]++; return 1; } int f2(){ function_counter[1
