version compatiblity for older maraidb version and new ones is important: im using still this version commit id f5821aaf7731e1f74b970fdaf186b945ae012c9d

my personal fix is removing this part inside .cc code for making code ready for gcc 16.1
sed -i 's/,evex512//' mysys/crc32/crc32c_x86.cc

this is compile error

mariadb mit latest toolchain also glibc und gcc 16.1 compile schlägt fehl: 128/1822] /usr/bin/cc -DHAVE_CONFIG_H -D_FILE_OFFSET_BITS=64 -I/root/compile/mariadb/wsrep-lib/include -I/root/compile/mariadb/wsrep-lib/wsrep-API/v26 -I/root/compile/mariadb/build/include -I/root/compile/mariadb/include/providers -I/>
