Ask help for PETSc

[Chen, Changjun]

Hi Sir,
     My name is Changjun Chen. I am a postdoc in Michigan State University. Recently I use your perfect software PETSc. It is very good. But I still have one problem. I need your help.
     It is about the size of final executable. When I compile it, it is over 60 MB. This is too large. Maybe it have all the linear equation solvers.  but among them, I only need one method, for example JACOBI method, I do not need others.
     So how could I compile the codes that only contains this method?
     Thanks

Sincerely,
Changjun
