Here is an excerpt from the GNU make manual:
The targets which .SECONDARY depends on are treated as intermediate files,
*except that they are never automatically deleted*... .SECONDARY with no
prerequisites causes all targets to be treated as secondary (i.e., *no
target
is removed because it is considered intermediate*).
It sounds to me like you are trying to delete your object files after they
are added to the archive. The .SECONDARY target is designed to keep
intermediate files from being deleted automatically, which is the normal
behavior. I've noticed that when it comes to creating archives, GNU make is
a bit flaky, not deleting object files when the manual tells you it will. I
believe it will always err on the side of safety - eg., never delete
anything unless it's absolutely sure it should. Here's a makefile that will
do what you want:
sources = main.c
objects = main.o
CC = gcc
*RM = -rm
*
main : $(sources)
$(AR) rv $(objects)
* $(RM) $(objects)
* $(CC) $(sources)
