The branch stable/13 has been updated by arichardson: URL: https://cgit.FreeBSD.org/src/commit/?id=edb96bf587fe89736d87fd12409cc734c52919a8 commit edb96bf587fe89736d87fd12409cc734c52919a8 Author: Alex Richardson <arichardson@FreeBSD.org> AuthorDate: 2021-02-10 11:05:02 +0000 Commit: Alex Richardson <arichardson@FreeBSD.org> CommitDate: 2021-03-17 09:59:32 +0000 Fix crossbuild bootstrap tools build with Clang 12 Clang 12 no longer allows re-defining a weak symbol as non-weak. This happed here because we compile err.c with _err defined to err. To fix this, use the same approach as the libc namespace.h (cherry picked from commit 02af91c52e71e8a0f47251e637c9687f35d45dd9) --- tools/build/libc-bootstrap/namespace.h | 4 +++- tools/build/libc-bootstrap/un-namespace.h | 5 ++++- 2 files changed, 7 insertions(+), 2 deletions(-) diff --git a/tools/build/libc-bootstrap/namespace.h b/tools/build/libc-bootstrap/namespace.h index 73e27f8cb02b..2c242f88072d 100644 --- a/tools/build/libc-bootstrap/namespace.h +++ b/tools/build/libc-bootstrap/namespace.h @@ -45,7 +45,9 @@ #define _writev(a, b, c) writev(a, b, c) #define _fsync(a) fsync(a) #define _getprogname() getprogname() -#define _err(...) err(__VA_ARGS__) +/* These two need to be renamed to build libc/gen/err.c */ +#define err _err +#define warn _warn #define _pthread_mutex_unlock pthread_mutex_unlock #define _pthread_mutex_lock pthread_mutex_lock diff --git a/tools/build/libc-bootstrap/un-namespace.h b/tools/build/libc-bootstrap/un-namespace.h index 398707791792..f08ab41ea543 100644 --- a/tools/build/libc-bootstrap/un-namespace.h +++ b/tools/build/libc-bootstrap/un-namespace.h @@ -36,5 +36,8 @@ * $FreeBSD$ */ #pragma once -/* This can be empty when building the FreeBSD compatible bootstrap files */ + +/* Undo the changes made by namespace.h */ +#undef err +#undef warn
