Fails in the link for me:
Linking CXX executable ../../../../bin/include-what-you-use
../../../../lib/libclangAST.a(InheritViz.cpp.o): In function `clang::InheritanceHierarchyWriter::WriteNode(clang::QualType, bool)':
/local/brs/work/llvm-source/tools/clang/lib/AST/InheritViz.cpp:80: undefined reference to `llvm::DOT::EscapeString(std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)'
../../../../lib/libclangAST.a(InheritViz.cpp.o): In function `clang::CXXRecordDecl::viewInheritance(clang::ASTContext&) const':
/local/brs/work/llvm-source/tools/clang/lib/AST/InheritViz.cpp:160: undefined reference to `llvm::DisplayGraph(llvm::sys::Path const&, bool, llvm::GraphProgram::Name)'
I'm using GNU ld on GNU/Linux. Presumably the linker behaviour is
what's different. Building with VERBOSE=1 shows that libLLVMSupport.a
(which defines llvm::DOT::EscapeString()) and so on are being included
in the link line. By adding copies of such libraries to the link line
(linking on the command-line rather than through make) I can link it.
Presumably some change to CMakeLists.txt would fix it, but I'm not sure
what. Maybe the list of clang dependencies is in the wrong order or
