Hi,
When building 32-bit lib for v4l-utils, met the QA warning issue.

After investigating,
meta-openembedded/meta-oe/recipes-multimedia/v4l2apps/v4l-utils_1.26.1.bb
#v4l2 explicitly sets _FILE_OFFSET_BITS=32 to get access to #both 32 and 64 bit
file APIs. But it does not handle the time side?
#Needs further investigation
GLIBC_64BIT_TIME_FLAGS = ""
GLIBC_64BIT_TIME_FLAGS = " -D_TIME_BITS=64 -D_FILE_OFFSET_BITS=64" which
defined in oe-core/meta/conf/distro/include/time64.inc was reset, so result in
this QA issue.
when comment GLIBC_64BIT_TIME_FLAGS = "" , there is build error.
/build-v4l/tmp-glibc/work/core2-32-wrsmllib32-linux/lib32-v4l-utils/1.26.1+git/lib32-recipe-sysroot/usr/include/features-time64.h:26:5:
error: #error "_TIME_BITS=64 is allowed only with _FILE_OFFSET_BITS=64"
26 | # error "_TIME_BITS=64 is allowed only with _FILE_OFFSET_BITS=64"
the build error is caused by v4l-utils meson.build:
v4l2_wrapper_args = [
# As the library needs to provide both 32-bit and 64-bit versions
# of file operations, disable transparent large file support (fixes
# 'Error: symbol `open64/mmap64' is already defined' compile failure
# otherwise)
'-U_FILE_OFFSET_BITS',
'-D_FILE_OFFSET_BITS=32',
'-D_LARGEFILE64_SOURCE',
]
D_FILE_OFFSET_BITS was reset to 32 during compile.
Is there any solution for this issue?
Thanks,
Haixiao
