[LLVMdev] Error while compiling .cpp

Actually I started with hello.cpp povided as an example pass and modified and made my pass which does randomization. I have been working on it and running over programs and it always worked fine but now lately i had checked out a newer version (llvm)which i believed was working fine too but now as i did some modifications and tried to compile my pass i got these errors.
My pass simply randomization of basic blocks.
Also I have yet not found a simple way to calculate basic block size in a function.There are tools that give me function size in bytes etc etc ....but not of basic block.I got reply that I have to see what my block does and then calculate size...what does that mean ? iterating over instructions and add the size of the instructions ?how do i determine that ?
Sorry for tons of questions but I would appreciate your help :-)

Can you give a little more context about what you're doing?
