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.
