GCC-15 does a big change, it changes the default C compilation language standard to -std=gnu23. That cause lots of "old style" C codes hit building errors. On the other word, current xfstests can't be used with GCC-15. So use a fixed language standard -- "-std=gnu11" (to match the kernel and xfsprogs). Signed-off-by: Zorro Lang <zlang@xxxxxxxxxx> --- Hi, 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.
