makefile issues - can't find .h path


have two questions pertaining to the makefile.

first, the makefile never actually executes the commands to make my object
files, but instead only tries to create the executable for the main project
file. i am fairly certain the makefile is formatted correctly since it was
working earlier. could the path environment variable for the .h’s have been
changed or something else…

i was also wondering if anyone could give me any advice on how to deal with
compiling lib files with circular dependencies.

thanks, sutin
