[cfe-dev] undefined symbol: llvm::Triple::getDarwinNumber when linking with libLLVMSystem.a

Hello,
I'm running into some linking problems I can't seem to solve with
libLLVMSystem.a (and other libraries)
The linker can find the symbol for: getOSAndEnvironmentName(), but not
for: getDarwinNumber()
Here's a crude code snipit for example:
llvm::Triple triple;
unsigned a,b,c;
triple.getDarwinNumber(a, b, c);
triple.getOSAndEnvironmentName();
...and the link error is below at the end of this email. I also get
similar link errors for symbols like:
"llvm::StringMapImpl::FindKey(llvm::StringRef const&) const",
referenced from:
llvm::StringMap<bool, llvm::MallocAllocator>::find(llvm::StringRef
const&) constin libclangBasic.a(Targets.o)
"llvm::raw_ostream::write(char const*, unsigned long)", referenced from:
llvm::raw_ostream::operator<<(llvm::StringRef const&)in
libclangBasic.a(SourceManager.o)
"llvm::BumpPtrAllocator::DefaultSlabAllocator", referenced from:
__ZN4llvm16BumpPtrAllocator20DefaultSlabAllocatorE$non_lazy_ptr
in libclangBasic.a(SourceManager.o)
Any help would be appreciated.
Craig
