Description:
Generating header files
Applicability:
all
Files:
Depends-on:
configure.ac:
Makefile.am:
# In 'sed', replace the pattern space with a "DO NOT EDIT" comment.
SED_HEADER_NOEDIT = s,.*,/* DO NOT EDIT! GENERATED AUTOMATICALLY! */,
# '$(SED_HEADER_STDOUT) -e "..."' runs 'sed' but first outputs "DO NOT EDIT".
SED_HEADER_STDOUT = sed -e 1h -e '1$(SED_HEADER_NOEDIT)' -e 1G
# '$(SED_HEADER_TO_AT_t) FILE' copies FILE to $@-t, prepending a leading
# "DO_NOT_EDIT". Although this could be done more simply via:
# SED_HEADER_TO_AT_t = $(SED_HEADER_STDOUT) > $@-t
# the -n and 'w' avoid a fork+exec, at least when GNU Make is used.
SED_HEADER_TO_AT_t = $(SED_HEADER_STDOUT) -n -e 'w $@-t'
# Use $(gl_V_at) instead of $(AM_V_GEN) or $(AM_V_at) on a line that
# is its recipe's first line if and only if @NMD@ lines are absent.
@NMD@gl_V_at = $(AM_V_at)
@!NMD@gl_V_at = $(AM_V_GEN)
