Hi Don,
I removed the extra “-I” directives but I still get the same result.
Hi Paul:
Why are you explicitly including …/c++/4.2.1?
If clang was compiled correctly, it should be able to find it’s own c++ headers – on OSX, that’s most likely libc++ headers. Try running:
clang++ -v -c -x c++ - < /dev/nullhth…

I am writing a parser for c++.
I am developing on a Mac. OS X Sierra 10.12.1
I am frustrated by the fact that I cannot compile even the simplest c++ code because clang 4.0 finds errors in the clang headers themselves! for example:
#include “clang/AST/ASTContext.h”
#include “clang/AST/ASTConsumer.h”
#include "clang/AST/
#include “clang/RecursiveASTVisitor.h”
#include “clang/Frontend/ASTConsumers.h”
#include “clang/Frontend/FrontendActions.h”
#include “clang/Frontend/CompilerInstance.h”
#include “clang/Tooling/CommonOptionsParser.h”
#include “clang/Tooling/Tooling.h”
#include “clang/Rewrite/Core/Rewriter.h”
#include “llvm/Support/raw_ostream.h”
#include
#includeint main( void )
{
return 0;
}
I have been trying to solve this by examining others’ Makefiles but to no avail.
This is the result of my latest effort:
