Error creating clang

Question

I am trying to create Clang on Linux (Amazon EC2). I run make according to the manual at:

http://clang.llvm.org/get_started.html

I get the following communication error messages:

llvm[2]: Linking Debug+Asserts executable opt /home/ec2-user/benchmark/build/tools/opt/Debug+Asserts/opt.o: In function `llvm::ParseIR(llvm::MemoryBuffer*, llvm::SMDiagnostic&, llvm::LLVMContext&)': opt.cpp:(.text._ZN4llvm7ParseIREPNS_12MemoryBufferERNS_12SMDiagnosticERNS_11LLVMContextE[llvm::Pars eIR(llvm::MemoryBuffer*, llvm::SMDiagnostic&, llvm::LLVMContext&)]+0x5f): undefined reference to `llvm::ParseBitcodeFile(llvm::MemoryBuffer*, llvm::LLVMContext&, std::basic_string<char, std::char_traits<char>, std::allocator<char> >*)' collect2: ld returned 1 exit status make[2]: *** [/home/ec2-user/benchmark/build/Debug+Asserts/bin/opt] Error 1 make[2]: Leaving directory `/home/ec2-user/benchmark/build/tools/opt' make[1]: *** [opt/.makeall] Error 2 make[1]: Leaving directory `/home/ec2-user/benchmark/build/tools' make: *** [all] Error 1 

Does anyone know what this means?

Edit: I rebuilt the entire project from svn, and now I get the following error:

  COMPILE: clang_linux/asan-i386/i386: /home/ec2-user/benchmark/llvm/projects/compiler-rt/lib/asan/asan_rtl.cc /home/ec2-user/benchmark/llvm/projects/compiler-rt/lib/asan/asan_rtl.cc:28:10: fatal error: 'new' file not found #include <new> ^ 1 error generated. make[5]: *** [/home/ec2-user/benchmark/build/tools/clang/runtime/compiler-rt/clang_linux/asan-i386/i386/SubDir.lib__asan/asan_rtl.o] Error 1 make[5]: Leaving directory `/home/ec2-user/benchmark/llvm/projects/compiler-rt' make[4]: *** [BuildRuntimeLibraries] Error 2 make[4]: Leaving directory `/home/ec2-user/benchmark/build/tools/clang/runtime/compiler-rt' make[3]: *** [compiler-rt/.makeall] Error 2 make[3]: Leaving directory `/home/ec2-user/benchmark/build/tools/clang/runtime' make[2]: *** [all] Error 1 make[2]: Leaving directory `/home/ec2-user/benchmark/build/tools/clang' make[1]: *** [clang/.makeall] Error 2 make[1]: Leaving directory `/home/ec2-user/benchmark/build/tools' make: *** [all] Error 1

I followed this up and I was able to successfully create it in the first shot.

I think you are having problems with your C++ standard library headers . So you need to follow Step #6 in the above link!

Start a new build and make sure that you satisfy this prerequisite.
