First the build failure is only raised with uclibc-ng on mips64. Secondly, fstatat is defined as extern if __USE_FILE_OFFSET64 is not defined [1] however its implementation is protected by "ifdef __NR_fstatat64" [2] __NR_fstatat64 is defined by: #if __WORDSIZE == 64 && defined __NR_newfstatat # define __NR_fstatat64 __NR_newfstatat #endif So, for an unknown reason, I assume that __NR_newfstatat is not defined. In this case, uclibc-ng doesn't define any fallback [3] resulting in the build failure. > > Kind regards, > Petr Best Regards, Fabrice [1] https://github.com/wbx-github/uclibc-ng/blob/ab1dd83bec59c9e65c31efd6e887182948f627be/include/sys/stat.h#L241 [2] https://github.com/wbx-github/uclibc-ng/blob/ab1dd83bec59c9e65c31efd6e887182948f627be/libc/sysdeps/linux/common/fstatat.c#L18 [3] https://github.com/wbx-github/uclibc-ng/blob/ab1dd83bec59c9e65c31efd6e887182948f627be/libc/sysdeps/linux/common/fstatat.c#L34 _______________________________________________ buildroot mailing list buildroot@buildroot.org https://lists.buildroot.org/mailman/listinfo/buildroot ^ permalink raw reply [flat|nested] 3+ messages in thread

Thanks for confirming that it's bug/issue on uclibc-ng on mips64. It'd be worth to at least report it to them.
