Subject: bug#65333: SCM_UNPACK triggers Werror=volatile in c++20
Date: Wed, 16 Aug 2023 08:41:14 +0200 [thread overview]
Message-ID: <0ab72e1c-ab7b-2d48-7fd2-2dc9cb404a50@suse.de> (raw)
Hi,
I tried to build gdb with guile support with -std=c++20 and ran into:
...
In file included from /usr/include/guile/2.0/libguile/__scm.h:479,
from /usr/include/guile/2.0/libguile.h:31,
from /data/vries/gdb/src/gdb/guile/guile-internal.h:30,
from /data/vries/gdb/src/gdb/guile/guile.c:37:
/usr/include/guile/2.0/libguile/gc.h: In function ‘scm_unused_struct*
scm_cell(scm_t_bits, scm_t_bits)’:
/usr/include/guile/2.0/libguile/tags.h:98:63: error: using value of
assignment with ‘volatile’-qualified left operand is deprecated
[-Werror=volatile]
98 | # define SCM_UNPACK(x) ((scm_t_bits) (0? (*(volatile SCM
*)0=(x)): x))
| ~~~~~~~~~~~~~~~~~~~^~~~~
...
FWIW, I ran into the same with guile 3.0.x.
Thanks,
- Tom
