>Synopsis: Shell commands within make that start with '@' don't work
>Severity: serious
>Priority: medium
>Category: bin
>Release: FreeBSD 2.2-CURRENT i386
>Class: sw-bug
>Environment:
FreeBSD-2.2 current
>Description:
When a makefile has a target with embedded shell comands that start
with @, it will not execute them properly, actually seeking a
command that begins with '@' (say @for) rather than just not echoing the
command in question.
>How-To-Repeat:
A makefile fragment of the form
# a very simple makefile...
pmake::
@for flag in ${MAKEFLAGS} ''; do \
case "$$flag" in *=*) ;; *[i]*) set +e;; esac; done; \
@for i in develhdrs/local; do if [ -d $(DESTDIR)$$i ]; then \
set +x; else (set -x; $(MKDIRHIER) $(DESTDIR)$$i); fi \
done
@echo 'make started.'
@for i in *.c; do \
echo $i; \
done
cc -I. -c *.c
cd lst.lib; cc -I.. -c *.c
cc *.o lst.lib/*.o -o pmake
@echo 'make completed.'
will cause an error like the following -
@for: not found
*** Error code 2
>Fix:
Unknown at this stage - looks like a perverse make bug
