Subject: [PATCH][gdb/build] Fix build breaker in language.c with gcc 7.5.0
Date: Fri, 5 Aug 2022 17:18:40 +0200 [thread overview]
Message-ID: <20220805151838.GA25573@delia> (raw)
Hi,
When building gdb on openSUSE Leap 15.3, using gcc 7.5.0, I run into:
...
gdb/language.c: In constructor ‘constexpr language_gdbarch::language_gdbarch()’:
gdb/language.c:921:8: error: use of deleted function \
‘language_arch_info::language_arch_info(const language_arch_info&)’
struct language_gdbarch
^~~~~~~~~~~~~~~~
In file included from gdbsupport/common-defs.h:104:0,
from gdb/defs.h:28,
from gdb/language.c:31:
gdb/language.h:95:28: note: declared here
DISABLE_COPY_AND_ASSIGN (language_arch_info);
^
include/ansidecl.h:342:3: note: in definition of macro \
‘DISABLE_COPY_AND_ASSIGN’
TYPE (const TYPE&) = delete; \
^~~~
gdb/language.c: In function ‘language_gdbarch* get_language_gdbarch(gdbarch*)’:
gdb/language.c:936:22: note: synthesized method ‘constexpr \
language_gdbarch::language_gdbarch()’ first required here
l = new struct language_gdbarch;
^~~~~~~~~~~~~~~~
...
This seems to be fixed by this change in the struct language_gdbarch
definition:
...
- struct language_arch_info arch_info[nr_languages] {};
+ struct language_arch_info arch_info[nr_languages];
...
Tested on x86_64-linux.
Any comments?
Thanks,
- Tom
