@cfriedt I think zephyr/subsys/net/lib/lwm2m/Kconfig Line 230 in e58c568 |

Any update on this? I have several PRs blocked where CI is failing due to this issue. |

I won't be at my desk for at least another hour. Feel free to make another PR for the time being |
https://github.com/zephyrproject-rtos/zephyr/actions/runs/\ 15014534061/job/42189411225 We were seeing a linker error of the form ``` picolibc/x86_64-zephyr-elf/lib/32/libc.a(libc_time_time.c.o): \ in function `time': time.c:(.text.time+0x11): undefined reference to `gettimeofday' ``` Update the dependency from CONFIG_POSIX_TIMERS to CONFIG_XSI_SINGLE_PROCESS for gettimeofday(). Note: this is really only a workaround. The proper solution would be to have libc functions not depend on POSIX functions. Specifically, here https://github.com/zephyrproject-rtos/picolibc/blob/\ 51a8b32857e75345c37652a80b5cda98b28d69e5/newlib/libc/time/\ time.c#L54 and here https://github.com/zephyrproject-rtos/zephyr/blob/\ 3a4e128/lib/libc/common/\ source/time/time.c#L17 Also mentioned in zephyrproject-rtos#89068 Signed-off-by: Chris Friedt <[email protected]>
