[LLVMdev] how to dynamically load a pass

[xli3 at uiuc.edu]

I tried to make my pass dynamically loadable cause it's too
slow to compile the whole system. I copied the Makefile from
Hello directory and changed the name. But when I type 'gmake'
 under the directory of my pass. I always got the following
error message. I cannot figure out why. Can you have a look
and let me know how to fix it?

thanks a lot,
