Bug ID: 31624
Summary: Does not build on 32-bit architectures with compiler
defaulting to -D_FILE_OFFSET_BITS=64 -D_TIME_BITS=64
Product: glibc
Version: 2.40
Status: NEW
Severity: normal
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: aurelien at aurel32 dot net
CC: drepper.fsp at gmail dot com
Target Milestone: ---
Trying to build glibc on a 32-bit architectures with a compiler defaulting to
-D_FILE_OFFSET_BITS=64 -D_TIME_BITS=64 like it is now the case in Ubuntu and
Debian leads to the following build issue:
gcc check_fds.c -c -std=gnu11 -fgnu89-inline -g -O2 -Wall -Wwrite-strings
-Wundef -Werror -fmerge-all-constants -frounding-math -fno-stack-protector
-fno-common -Wp,-U_FORTIFY_SOURCE -Wstrict-prototypes -Wold-style-definition
-fmath-errno -fPIC -fno-stack-protector -DSTACK_PROTECTOR_LEVEL=0

These flags are not meant to be used to build glibc itself, the user installed
programs (such as ldconfig) are using 64 bit time_t.

--- Comment #2 from Sam James <sam at gentoo dot org> ---
The problem is, glibc doesn't provide a way to easily say "I want to always
have 64-bit time_t and LFS" (I did ask:
https://inbox.sourceware.org/libc-alpha/A6582515-25ED-4F71-B924-4431F8139376@gentoo.org/).
Debian has therefore patched it into their GCC spec files.
What's the suggested alternative?

I think you could add an escape hatch in the specs fragment, like this:
*cpp_options:
+ %{!D_GENTOO_EVADE_TIME_BITS:-D_FILE_OFFSET_BITS=64 -D_TIME_BITS=64}
And then build glibc with -D_GENTOO_EVADE_TIMEBITS.

just adding here that both Debian and Ubuntu will use the distro-neutral flag
_DISTRO_EVADE_TIME_BITS for that.
