From c40b1da2fd64bb10f120f85966b44f0d2bb315f8 Mon Sep 17 00:00:00 2001 From: fanquake Date: Fri, 14 Apr 2023 10:45:34 +0100 Subject: depends: fix compiling bdb with clang-16 on aarch64 Compiling bdb with clang-16 on aarch64 (hardware) currently fails: ```bash make -C depends/ bdb CC=clang CXX=clang++ ... checking for mutexes... UNIX/fcntl configure: WARNING: NO SHARED LATCH IMPLEMENTATION FOUND FOR THIS PLATFORM. configure: error: Unable to find a mutex implementation ``` Looking at config.log we've got: ```bash configure:18704: checking for mutexes configure:18815: clang -o conftest -pipe -std=c11 -O2 -Wno-error=implicit-function-declaration -Wno-error=format-security -I/bitcoin/depends/aarch64-unknown-linux-gnu/include -D_GNU_SOURCE -D_REENTRANT -L/bitcoin/depends/aarch64-unknown-linux-gnu/lib conftest.c -lpthread >&5 conftest.c:45:1: error: type specifier missing, defaults to 'int'; ISO C99 and later do not support implicit int [-Wimplicit-int] main() { ^ int conftest.c:50:2: warning: call to undeclared library function 'exit' with type 'void (int) __attribute__((noreturn))'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration] exit ( ^ conftest.c:50:2: note: include the header or explicitly provide a declaration for 'exit' 1 warning and 1 error generated. ``` Clang-16 changed `-Wimplicit-function-declaration` and `-Wimplicit-int` warnings into errors, see: https://releases.llvm.org/16.0.0/tools/clang/docs/ReleaseNotes.html#potentially-breaking-changes. > The -Wimplicit-function-declaration and -Wimplicit-int warnings now > default to an error in C99, C11, and C17. As of C2x, support for implicit > function declarations and implicit int has been removed, and the > warning options will have no effect. Specifying -Wimplicit-int in > C89 mode will now issue warnings instead of being a noop.
