${REINPLACE_CMD} on Makefile

[indiocolifa]

I'm trying to use the 'a' sed command on a Makefile to insert a line. This is a Makefile for a port that's currently broken.

$@{REINPLACE_CMD} '|<iostream.h>|a \\ \#include <ios>|'

The problem is that 'a' requires the text to be replaced on a new line and I don't know how to put that newline character in the Makefile. make is very picky about tabs, blanks, etc.

sed a command syntax ref:

[1addr]a \
text

Thank you...

I think this can't be done with pmake as it treats '\' followed by newline as a space unlike gmake where this is passed 'as it is' to the shell.

Ofcourse, I may be wrong. I would be interested to know if there is a way to do this. Try asking on the fbsd ML or freebsdforum.

You can create the sed command file in Make

FILES= a.src b.src

EDIT    : sedcmd
        sed -f sedcmd ${FILES}

sedcmd  :
        echo '/<iostream.h>/a\\' >${.TARGET}
        echo '#include <ios>' >>${.TARGET}

This will produce the following

$ cat sedcmd
/<iostream.h>/a\
#include <ios>

IMO, you're better off just using a patch file. Too many replacements like this make the Makefile unneccesarily overbloated and pehaps confusing to everyone else. REINPLACE_CMD is good for replacing many instances of something in a single file or something that may be dependent upon architecture, etc.
