gen-header: port to BusyBox ‘sed’ Problem reported by Tim Rühsen in: https://lists.gnu.org/r/bug-gnulib/2022-01/msg00004.html * modules/gen-header (SED_HEADER_NOEDIT): Replace instead of prepend. (SED_HEADER_STDOUT, SED_HEADER_TO_AT_t): Adjust to that change. Do not use ‘w foo’ twice in the same script, as BusyBox ‘sed’ mistakenly opens ‘foo’ for output twice, thus losing some output.

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) Include: License: LGPLv2+ Maintainer: bug-gnulib@gnu.org
