That check is for sys/sysctl.h, if that file still exists on X32 then it's not the right macro to fix. A better fix would be around HAVE_DECL_RANDOM_UUID in config.h.guess. > Or there might be a better solution, like pre-defining HAVE_RANDOM_UUID 0 > (or HAVE_DECL_RANDOM_UUID in the current version) A suitable fix would be to pass `-DHAVE_DECL_RANDOM_UUID=0` on X32. Note that RANDOM_UUID is an enum not a macro. > There was an attempt to remove sysctl(), but it was restored here for > older kernels: > https://github.com/wahern/luaossl/commit/7d6202bfa85e8f0bf90590a9381757f15e296a33 > Calls to sysctl remain in the current version .
