Actually it's not weird, the order in which you compile EPICS Base, your 
support modules such as Asyn and your IOC applications is important, and you 
usually have to do a 'make rebuild' at the top of your IOC applications if 
there changes in any of the others or if you add a new module to the 
configure/RELEASE file.

There is no automatically generated build log, but you can create one yourself 
using the tee program, the command lines below show how to do that  instead of 
just running plain 'make' (the commands are different depending on which shell 
program you use):

sh or bash:
    make 2>&1 | tee build.log
csh or tcsh:
    make |& tee build.log
