Hi,
I tried to implement an 'llc'-like tool in my project to manage
different passes and a target machine.
I use given llvm project structure to avoid problems but I have a link
problem and don't know how to solve it:
The target machine uses 'FindUsedTypes' pass and when I try to use my
target machine in the tool I got "Undefined symbols:
"llvm::FindUsedTypes ... ld: symbol(s) not found"
I tried following link options:
LLVMLIBS = LLVMAnalysis.a
LINK_COMPONENTS = analysis
LINK_COMPONENTS = all
But nothing solved my problem (in fact the last made some other
problems with code I never touched).
I would be very appreciated for any idea.
Thanks a lot
Nico

Dear Nico, I believe you need to add LLVMipa to the list of libraries to link into your tool. FindUsedTypes::ID is defined in lib/Analysis/IPA. I think it would be LLVMipa.a if you added it to LLVMLIBS and ipa if you added it to LINK_COMPONENTS. -- John T.

Dear John, thanks! I was irritated by the path of the header file/declaration. It is not like the definition in a subdirectory. Sorry my fault. Is there an overview where classes and link options are mapped to each other?
