Hi nihkil,
Try using a "macro":
# $(1) is retry count: integer constant in shell test syntax
# $(2) is command
#
define retry-times
i=0; while [ $$i -lt $(1) ]; do ($(2)) && exit 0; i=$$(( i + 1 ));
done ; exit 1
endef
target: prerequisite
$(call retry-times,5,your command here)
Fixed retries version:
# $(1) is command
#
define retry-3-times
($(1)) && exit 0 || ($(1)) && exit 0 || ($(1)) && exit 0 || exit 1
endef
target: prerequisite
$(call retry-3-times,your command here)
We insert the command in parentheses not just for syntactic hygiene but
to get it to run in a subshell. This way our command can contain
subcommands like "exit 1" without terminating the retry logic.
Cheers ...

GNU make has no built-in facility to retry failed commands.
