Bug #683
Updated by Pierre-Louis Bonicoli over 4 years ago
bip build failed with GCC 10 and glibc 2.31 (Fedora 32 mass rebuild). I'm attaching a patch suggested by DJ Delorie which fixes the build at least (didn't check yet that the built package works OK). Here's the build error: <pre> gcc -DHAVE_CONFIG_H -I. -Wall -Wextra -Werror -O2 -g -pipe -Wall -Werror=format-security -Wp,-D_FORTIFY_SOURCE=2 -Wp,-D_GLIBCXX_ASSERTIONS -fexceptions -fstack-protector-strong -grecord-gcc-switches -specs=/usr/lib/rpm/redhat/redhat-hardened-cc1 -specs=/usr/lib/rpm/redhat/redhat-annobin-cc1 -m64 -march=zEC12 -mtune=z13 -fasynchronous-unwind-tables -fstack-clash-protection -fPIE -Wno-unused-result -Wno-error=format-truncation -c -o libbip_a-irc.o `test -f 'irc.c' || echo './'`irc.c In file included from /usr/include/string.h:495, from irc.c:16: In function 'strncpy', inlined from 'get_str_elem' at irc.c:646:3, inlined from 'irc_cli_startup.constprop' at irc.c:730:9: /usr/include/bits/string_fortified.h:106:10: error: '__builtin_strncpy' output truncated before terminating nul copying as many bytes from a string as its length [-Werror=stringop-truncation] 106 | return __builtin___strncpy_chk (__dest, __src, __len, __bos (__dest)); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ irc.c: In function 'irc_cli_startup.constprop': irc.c:642:13: note: length computed here 642 | c = str + strlen(str); | ^~~~~~~~~~~ cc1: all warnings being treated as errors </pre>
