gnu make - How to split in GNU makefile list of files into separate lines -

i have variable containing list of files separated string _newline_. need output variable file each file in separate line. trick needs works on freebsd , solaris.

this trying now:

echo "lib/alarms-1.2/priv/snmp_conf/agent.conf: lib/alarms/priv/snmp_conf/agent.conf_newline_lib/alarms-1.2/priv/snmp_conf/agent.conf.src: lib/alarms/priv/snmp_conf/agent.conf.src_newline_lib/alarms-1.2/priv/snmp_conf/community.conf: lib/alarms/priv/snmp_conf/community.conf" | sed 's|_newline_|\'$'\n|g'

this works on freebsd , in shell on solaris. when run in gnumakefile on solaris getting (notice $ @ end of each line):

lib/alarms-1.2/priv/snmp_conf/agent.conf: lib/alarms/priv/snmp_conf/agent.conf$ lib/alarms-1.2/priv/snmp_conf/agent.conf.src: lib/alarms/priv/snmp_conf/agent.conf.src$ lib/alarms-1.2/priv/snmp_conf/community.conf: lib/alarms/priv/snmp_conf/community.conf$

if remove \'$' sed works on solaris doesn't on freebsd. maybe there way of telling version utilize depending on scheme makefile executed?

edit: solution proposed bobbogo created exemplary makefile provides desired outcome , seems working on both freebsd , solaris:

one-line := lib/alarms-1.2/priv/snmp_conf/agent.conf: lib/alarms/priv/snmp_conf/agent.conf_newline_lib/alarms-1.2/\ priv/snmp_conf/agent.conf.src: lib/alarms/priv/snmp_conf/agent.conf.src_newline_lib/alarms-1.2/priv/snmp_conf/comm\ unity.conf: lib/alarms/priv/snmp_conf/community.conf many-lines := { echo '$(subst _newline_,' && echo ',${one-line})'; } .phony: all: $(shell $(many-lines) > test.txt)

if gnu make, in make.

one-line := lib/alarms-1.2/priv/snmp_conf/agent.conf: lib/alarms/priv/snmp_conf/agent.conf_newline_lib/alarms-1.2/priv/snmp_conf/agent.conf.src: lib/alarms/priv/snmp_conf/agent.conf.src_newline_lib/alarms-1.2/priv/snmp_conf/community.conf: lib/alarms/priv/snmp_conf/community.conf define \n endef many-lines := $(subst _newline_,${\n},${one-line})

now ${many-lines} has want. annoyingly, it's quite hard utilize in shell lines. if this:

tgt: echo '${many-lines}'

make invoke separate shell each line. first shell invocation un-paired ' , exit error.

.oneshell: tgt: echo '${many-lines}'

will work in invasive sort of way. proper prepare ensure each line of ${many-lines} has valid sh syntax. mouthfull like:

echolines = $(subst ${\n},'${\n}echo ',echo '${many-lines}') .phony: aa aa: $(call echolines,${many-lines})

sheesh.
