GCC-15 does a big change, it changes the default language version for C compilation from -std=gnu17 to -std=gnu23. That cause lots of "old style" C codes hit build errors. On the other word, current xfstests can't be used with GCC-15. So -std=gnu17 can help that. Signed-off-by: Zorro Lang <zlang@xxxxxxxxxx> --- Hi, I send this patch just for talking about this issue. The upcoming gcc-15 does lots of changes, a big change is using C23 by default: https://gcc.gnu.org/gcc-15/porting_to.html xfstests has many old style C codes, they hard to be built with gcc-15. So we have to either add -std=$old_version (likes this patch), or port the code to C23. This patch is just a workaround (and a reminder for someone might hit this issue with gcc-15 too). If you have any good suggestions or experience (for this kind of issue) to share, feel free to reply.
