Both define struct sched_attr --> got build error "redefinition of struct sched_attr" This struct is defined into: - glibc 2.41: sysdeps/unix/sysv/linux/bits/sched.h - strace 6.10: src/sched_attr.h Note: glibc 2.40 + strace 6.10 are OK Please consider this point. 101608 1 randy.macleod 2025-04-10 14:34:29 +0000 I asked Yash to look at this briefly. He said: I didn't find any bug reported in glibc bugzilla for "redefinition of struct sched_attr". However, a similar case was addressed in Qemu with a patch by Khem : https://github.com/qemu/qemu/commit/27a8d899c7a100fd5aa040a8b993bb257687c393 https://patchwork.kernel.org/project/qemu-devel/patch/20241011193140.1047648-1-raj.khem@gmail.com/ Perhaps a similar macro check can be done for strace too. Anh, does this still happen for 5.2-M4 and/or master? Can you explain why we did not see this in our Yocto AB testing? What exactly are the steps to reproduce. 101684 2 anh.nguyen.pv 2025-04-18 03:24:18 +0000 Hi Randy, Sorry for my mistake. I got issue because I used old strace version with new glibc version. There is no issue with Yocto 5.2_M3. I will verify more carefully before creating a bug later. Best Regards, Anh Nguyen 101688 3 randy.macleod 2025-04-18 16:48:21 +0000 Anh, thanks for the follow-up. It's good that this isn't a bug that we missed.
