Subject: [Bug build/26647] New: [-Werror=array-parameter=] due to different declarations for __sigsetjmp
Date: Tue, 22 Sep 2020 13:07:16 +0000 [thread overview]
Message-ID: <bug-26647-131@http.sourceware.org/bugzilla/> (raw)
https://sourceware.org/bugzilla/show_bug.cgi?id=26647
Bug ID: 26647
Summary: [-Werror=array-parameter=] due to different
declarations for __sigsetjmp
Product: glibc
Version: unspecified
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: build
Assignee: unassigned at sourceware dot org
Reporter: vvinayag at arm dot com
CC: carlos at redhat dot com
Target Milestone: ---
After this patch [1], I am seeing this -Warray-parameter error when building
gcc:

cc1: all warnings being treated as errors
The build/host/target setup is:
Build: x86_64-linux-gnu (Ubuntu 18.04)
Host: x86_64-linux-gnu
Target: aarch64-none-linux-gnu, aarch64_be-none-linux-gnu,
arm-none-linux-gnueabi, arm-none-linux-gnueabihf
This was mentioned in
https://gcc.gnu.org/pipermail/gcc-patches/2020-September/554415.html and it
seems like the warning might need to be suppressed in glibc.
