We still have at least one CentOS 7 aarch64 machine that gets regular testing (not sure of the reason, since it's been EOL for a year and a half IIUC), and it builds fine: https://buildfarm.postgresql.org/cgi-bin/show_log.pl?nm=arowana&dt=2025-11-04%2004%3A56%3A57 > After modifying the code to add `include <asm/hwcap.h>`, the compilation > succeeded. We already have the following, so I'm not sure what you mean (or even what architecture you're running on): #if defined(HAVE_ELF_AUX_INFO) || defined(HAVE_GETAUXVAL) #include <sys/auxv.h> #if defined(__linux__) && !defined(__aarch64__) && !defined(HWCAP2_CRC32) #include <asm/hwcap.h> #endif #endif -- John Naylor Amazon Web Services
