llvm dev - Jun 2008 - [LLVMdev] Index to libraries?

There wouldn't happen to be an index telling one which libraries
define which symbols, would there?

For example, if I'm told

alvm.o: In function `llvm::Function::Create(llvm::FunctionType const*,
llvm::GlobalValue::LinkageTypes, std::basic_string<char,
std::char_traits<char>, std::allocator<char> > const&,
llvm::Module*)':
/farhome/hendrik/dv/llvm/llvm/include/llvm/Function.h:118: undefined reference
to `llvm::User::operator new(unsigned int, unsigned int)'
 
or

/farhome/hendrik/dv/lang/alvm/alvm.cpp:69: undefined reference to
`llvm::FunctionType::get(llvm::Type const*, std::vector<llvm::Type const*,
std::allocator<llvm::Type const*> > const&, bool)'

or even just

/farhome/hendrik/dv/lang/alvm/alvm.cpp:68: undefined reference to
`llvm::Type::Int32Ty'

how should I go about finding the proper library to link with?

Hi Hendrick,

All of the directories under llvm/lib correspond directly to the  
libraries that are built, so you should be able to just grep for the  
symbol definitions and add the corresponding library. Use llvm-config  
to discover transitive dependencies if possible.

Thanks.  By following your instructions I managed to establish that my
problems lay elsewhere.  That, in turn, enabled me to fix them.

The hardest place in a program to find a bug is anywhere the bug isn't.
