https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D233545 Bug ID: 233545 Summary: bin/sh: "export VAR" always defines VAR unlike other shells Product: Base System Version: CURRENT Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: bin Assignee: bugs@FreeBSD.org Reporter: jbeich@FreeBSD.org CC: jilles@FreeBSD.org Created attachment 199580 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D199580&action= =3Dedit v0 (blind backport) I'm trying to build a project that conditionally defines variables but alwa= ys exports them. With FreeBSD sh those unset end up defined with empty value. = If make/gmake/etc is later invoked ?=3D assignments are ignored. $ env -i sh -c 'export CC; printenv' | fgrep CC CC=3D $ env -i sh -c 'export CC; make -V CC' dash, pdksh, bash, zsh aren't affected. NetBSD sh fixed it in https://github.com/netbsd/src/commit/9ad7f3a0e1b5 --=20 You are receiving this mail because: You are the assignee for the bug.=
