Clang LLVM断言错误
我正在尝试使用LLVM/ClangAPI将源代码编译为LLVM IR clang_ir.cpp:Clang LLVM断言错误,clang,llvm,Clang,Llvm,我正在尝试使用LLVM/ClangAPI将源代码编译为LLVM IR clang_ir.cpp: #include <iostream> #include <clang/Driver/Compilation.h> #include <clang/Driver/Driver.h> #include <clang/Frontend/TextDiagnosticPrinter.h> #include <llvm/Support/Host.h>

原因是什么?它非常清楚地告诉你问题出在哪里。未设置
DiagnosticClient
。DiagnosticEngine
需要一个DiagnosticClient
——本质上是一个回调,用于说明发生诊断时要做什么
坦率地说,CLANC++的API中充满了恼人的狗屎。要求他们只在引擎构造函数中引用或指向客户机的指针,这太过分了。您只需习惯于在出现每个断言失败时修复它
