From e63ae12e399b846c5f97dbf3cb1e771f75263255 Mon Sep 17 00:00:00 2001 From: Jouzo <15011228+Jouzo@users.noreply.github.com> Date: Thu, 7 Apr 2022 09:30:33 +0100 Subject: [PATCH] Fix mutex detection when building bdb on macOS (#1191) * build: fix mutex detection when building bdb on macOS Starting with the Clang shipped with Xcode 12, Apple has enabled -Werror=implicit-function-declaration by default. This causes bdbs mutex detection to fail when building on macOS (not cross-compiling): checking for mutexes... UNIX/fcntl configure: WARNING: NO SHARED LATCH IMPLEMENTATION FOUND FOR THIS PLATFORM. configure: error: Unable to find a mutex implementation as previously emitted warnings are being turned into errors. i.e: error: implicitly declaring library function 'exit' with type 'void (int) __attribute__((noreturn))' [-Werror,-Wimplicit-function-declaration] Append -Wno-error=implicit-function-declaration to cflags so that -Wimplicit-function-declaration returns to being a warning, and the configure checks will succeed. Fixes #19411. * Use C++17 Co-authored-by: fanquake Co-authored-by: Prasanna Loganathar --- depends/packages/bdb.mk | 1 + 1 file changed, 1 insertion(+) diff --git a/depends/packages/bdb.mk b/depends/packages/bdb.mk index f983c754ab..f56346c500 100644 --- a/depends/packages/bdb.mk +++ b/depends/packages/bdb.mk @@ -9,6 +9,7 @@ define $(package)_set_vars $(package)_config_opts=--disable-shared --enable-cxx --disable-replication $(package)_config_opts_mingw32=--enable-mingw $(package)_config_opts_linux=--with-pic +$(package)_cflags+=-Wno-error=implicit-function-declaration $(package)_cxxflags=-std=c++17 $(package)_cppflags_mingw32=-DUNICODE -D_UNICODE endef
