https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D217613 --- Comment #7 from Simon J. Gerraty <sjg@FreeBSD.org> --- Sorry I should have been more explicit, I was refering to the dependency. If we tweak that makefile so it is consumable by both bmake and gmake % cat tmf .SUFFIXES: .ext .c VPATH =3D /tmp /tmp/target.ext: target.c @echo '@=3D$@ *=3D$* >=3D$> ^=3D$^' all: target.ext % we cannot have $*.c as source - gmake doesn't like it, bmake behaves as documented: % bmake -r -f tmf @=3D/tmp/target.ext *=3Dtarget >=3D/tmp/target.c ^=3D gmake just trims suffix: % make -r -f tmf=20 @=3D/tmp/target.ext *=3D/tmp/target >=3D ^=3Dtarget.c which I think is expected, we can better see what bmake is doing if we put = the $*.c back as a dependency, but qualify it. eg. cat tmf .SUFFIXES: .ext .c VPATH =3D /tmp /tmp/target.ext: ${.CURDIR}/$*.c @echo '@=3D$@ *=3D$* >=3D$> ^=3D$^' all: target.ext % % bmake -r -f tmf=20 bmake: don't know how to make /tmp//tmp/target.c. Stop but if we lose the ${.CURDIR}/ qualification it works: % bmake -r -f tmf=20 @=3D/tmp/target.ext *=3Dtarget >=3D/tmp/target.c ^=3D % on the rhs of the dependency only the suffix is trimed, once we are into the target context the directory is also. Bug? hard to say, it has behaved this way for 20+ years --=20 You are receiving this mail because: You are the assignee for the bug.=
