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

[Craig Mortensen]

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
