I assume you are using Visual Studio as your build tool? The LLVM project set turns into a bunch of Visual Studio project files, and my experience has been that they do not always coordinate correctly. Often just running the build again will solve a problem like this. I'm not really familiar with the sanitizers so I don't have any ideas about the specific error, if re-running the build doesn't solve it. --paulr From: llvm-dev [mailto:llvm-dev-bounces at lists.llvm.org] On Behalf Of mirchd via llvm-dev Sent: Tuesday, March 12, 2019 8:37 AM To: mirchd Cc: llvm-dev at lists.llvm.org Subject: Re: [llvm-dev] llvm compiled error Ping, any idea? thanks in advance~ 在 2019-03-11 22:44:12，"mirchd via llvm-dev" <llvm-dev at lists.llvm.org> 写道： Hello, when I build llvm from git source, some errors occured. 80>asan_new_delete.obj : error LNK2019: unresolved external symbol "void * __cdecl MemalignFromLocalPool(unsigned __int64,unsigned __int64)" (?MemalignFromLocalPool@@YAPEAX_K0 at Z)， "void * __cdecl operator new(unsigned __int64)" (??2 at YAPEAX_K@Z) 80>D:\program\llvm\build\Debug\lib\clang\9.0.0\lib\windows\clang_rt.asan_dynamic-x86_64.dll : fatal error LNK1120 80>“clang_rt.asan-dynamic-x86_64.vcxproj” fail. env: cmake x64 win10, visualstudio2017 15.9.8 please help, Best wishes, Dian Chen -------------- next part -------------- An HTML attachment was scrubbed...
