[LLVMdev] link problem with llvm-pass

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

PS: output from "make VERBOSE=1"
