I'm trying to make a library in Xcode that links against LLVM. I used the STL C++ template in Xcode 4.5.2, added libLLVMCore.a and libLLVMSupport.a to the link binaries phase, and made this call in my code:
llvm::LLVMContext& llvmCTX = llvm::getGlobalContext();
I get link errors against std::string and other STL classes:
Undefined symbols for architecture x86_64:
"std::string::copy(char*, unsigned long, unsigned long) const", referenced from:
llvm::sys::Path::makeUnique(bool, std::string*) in libLLVMSupport.a(Path.o)
"std::string::find(char const*, unsigned long, unsigned long) const", referenced from:
llvm::sys::getDefaultTargetTriple() in libLLVMSupport.a(Host.o)
.
.
.
Builds fine if I take out that line (the only line, so far) of LLVM code.
But code like this compiles fine:
std::string s = "Hello world";
std::printf("%s", s.c_str());
I figure I'm missing a lib, but I have no idea which.
TIA,

Rick
