Hello world :-) Are there any SED and MAKE experts around? :-) There is a piece of Makefile within NuttX RTOS simulator code that creates the linker scripts. I would like to fix the upstream so it builds out of the box on FreeBSD (*BSD). sed -e '/====/,/====/!d;//d' -e 's/__executable_start/_stext/g' \ -e 's/^\(\s\+\)\(\.init_array\)/\1\2 : { }\n\1.sinit/g' \ -e 's/^\(\s\+\)\(\.fini_array\)/\1\2 : { }\n\1.einit/g' \ -e 's/__init_array_start/_sinit/g' -e 's/__init_array_end/_einit/g' \ -e 's/__fini_array_start/_sfini/g' -e 's/__fini_array_end/_efini/g' >nuttx.ld It does not work with BSD sed but when I replace this with gsed all works fine. BSD sed complalins about trailinig backslash: sed: 1: "s/^\(\s\+\)\(\.init_arr ...": RE error: trailing backslash (\) Is there a way to fix that part so it works both with GNU sed and BSD sed? The easiest way would be adding ${SEDCMD} set to "gsed" on BSD and "sed" for the others (macOS also seems to use gnu sed). Another question is on Makefile. Project uses thousands of GNU syntax Makefiles. So I have to use gmake to build. Is there an elegant way to use BSD make here with no dramatic code modification? Any hints appreciated :-) Tomek -- CeDeROM, SQ7MHZ, http://www.tomek.cedro.info
