4Subject: [PATCH] fix err variable and function conflicts
5
6There comes below build failure with musl when
7ptest enabled.
8| In file included from ../../elfutils-0.176/tests/dwfl-proc-attach.c:33:
9| ../../elfutils-0.176/lib/system.h:63:35: error: called object 'err' is not a function or function pointer
10| #define error(status, errno, ...) err(status, __VA_ARGS__)
11| ^~~
12| ../../elfutils-0.176/tests/dwfl-proc-attach.c:92:5: note: in expansion of macro 'error'
13| error (-1, 0, "dwfl_linux_proc_attach pid %d: %s", pid,
14| ^~~~~
15| ../../elfutils-0.176/tests/dwfl-proc-attach.c:79:7: note: declared here
16| int err;
17| ^~~

19It is because there is no error.h in musl and
20the patch 0008-build-Provide-alternatives-for-glibc-assumptions-hel.patch
21has updated to use err.h to replace error.h
22and also added macro definiton as below when
23use musl.
24 #define error(status, errno, ...) err(status, __VA_ARGS__)
25
26And in err.h, there is below logic:
27_Noreturn void err(int, const char *, ...);
28
29But when ptest enabled, there comes below error
30as there is both variable and function defined
31to be err in tests/dwfl-proc-attach.c.
32So change the err variable's name to workaround
33the build failure with musl.

35Upstream-Status: Inappropriate [workaround in musl]
