Subject: Linux 5.5=rc1 kselftest rseq test build failure
Date: Tue, 10 Dec 2019 17:27:44 -0700 [thread overview]
Message-ID: <2d53b409-31e0-2245-e163-1ab26f52c841@linuxfoundation.org> (raw)
Hi Mathieu,
I am seeing rseq test build failure on Linux 5.5-rc1.
gcc -O2 -Wall -g -I./ -I../../../../usr/include/ -L./ -Wl,-rpath=./
param_test.c -lpthread -lrseq -o ...tools/testing/selftests/rseq/param_test
param_test.c:18:21: error: static declaration of ‘gettid’ follows
non-static declaration
18 | static inline pid_t gettid(void)
| ^~~~~~
In file included from /usr/include/unistd.h:1170,
from param_test.c:11:
/usr/include/x86_64-linux-gnu/bits/unistd_ext.h:34:16: note: previous
declaration of ‘gettid’ was here
34 | extern __pid_t gettid (void) __THROW;
| ^~~~~~
make: *** [Makefile:28: ...tools/testing/selftests/rseq/param_test] Error 1
The following obvious change fixes it. However, there could be reason
why this was defined here. If you think this is the right fix, I can
send the patch. I started seeing this with gcc version 9.2.1 20191008
diff --git a/tools/testing/selftests/rseq/param_test.c
