I'm currently testing
NUM_MATCH_SPLITS = @DEFAULT_MATCHPD_PARTITIONS@
-MATCH_SPLITS_SEQ = $(shell seq 1 $(NUM_MATCH_SPLITS))
+MATCH_SPLITS_SEQ = $(shell echo {1..$(NUM_MATCH_SPLITS)})
Which seems to work since it looks like we require an sh compatible shell.
Question is this right? From the existing
$(foreach header_var,$(shell sed < Makefile -n -e 's/^\([A-Z0-9_]*_H\)[
]*=.*/\1/p'),echo $(header_var)=$(shell echo
$($(header_var):$(srcdir)/%=.../%) | sed -e 's~\.\.\./config/~config/~' -e
's~\.\.\./common/config/~common/config/~' -e 's~\.\.\.[^ ]*/~~g') >>
tmp-header-vars;)
Rule this seems to be correct.
Thanks,
Tamar
