(if you know a better place i should be asking these questions, do
point me at those.)
Another make question... It would appear that variables have at least
two scopes, but parallel, not nested. Example:
DESTDIR=
SOURCES= foo bar baz
TARGETS:= ${SOURCES:C;^.+$;${DESTDIR}/&;}
SRCFILE= ${.TARGET:C,^${DESTDIR}/,,}
.BEGIN:
@echo "\$${DESTDIR}: ${DESTDIR}"
@echo "\$${TARGETS}: ${TARGETS}"
all: ${TARGETS}
${TARGETS}: ${SRCFILE}
@echo "SRC: ${SRCFILE} -> TGT: ${.TARGET}"
@#install ${SRCFILE} ${.TARGET}
.PHONY: all
roman@freepuppy ~/tmp 1126:0 > make all DESTDIR=/tmp/maketest
${DESTDIR}: /tmp/maketest
${TARGETS}: /foo /bar /baz
Graph cycles through /foo
Graph cycles through /bar
Graph cycles through /baz
`all' not remade because of errors.
here, DESTDIR has a value in the .BEGIN target "body", but not outside
it. how come the commandline assignment overrides the value at one
place, but not the other?
