Trying to build with xxhash,

[MikeFultonDev]

The logged configuration output (<datestamp>_config.log) has:

Configure found the following issues:

- Failed to find xxhash.h for xxhash checksum support.
- Failed to find zstd.h for zstd compression support.
- Failed to find lz4.h for lz4 compression support.

Checking configure.sh, we see:

ac_fn_c_check_header_compile "$LINENO" "xxhash.h" "ac_cv_header_xxhash_h" "$ac_includes_default"
if test "x$ac_cv_header_xxhash_h" = xyes
then :
  printf "%s\n" "#define HAVE_XXHASH_H 1" >>confdefs.h

and:

# -------------------------------------------------------
# Tests whether HEADER exists and can be compiled using the include files in
# INCLUDES, setting the cache variable VAR accordingly.

if eval test \${$3+y}

  printf %s "(cached) " >&6
else $as_nop
  cat confdefs.h - <<_ACEOF >conftest.$ac_ext
/* end confdefs.h.  */

eval ac_res=\$$3

printf "%s\n" "$ac_res" >&6; }
  eval $as_lineno_stack; ${as_lineno_stack:+:} unset as_lineno

} # ac_fn_c_check_header_compile

This references the variable INCLUDES

ac_fn_c_try_compile is:

ac_fn_c_try_compile ()
{
  as_lineno=${as_lineno-"$1"} as_lineno_stack=as_lineno_stack=$as_lineno_stack
  rm -f conftest.$ac_objext conftest.dbg conftest.beam

printf "%s\n" "$ac_try_echo"; } >&5
  (eval "$ac_compile") 2>conftest.err
  ac_status=$?
  if test -s conftest.err; then
    grep -v '^ *+' conftest.err >conftest.er1
    cat conftest.er1 >&5
    mv -f conftest.er1 conftest.err
  fi
  printf "%s\n" "$as_me:${as_lineno-$LINENO}: \$? = $ac_status" >&5
  test $ac_status = 0; } && {
   test -z "$ac_c_werror_flag" ||
   test ! -s conftest.err
       } && test -s conftest.$ac_objext
then :
  ac_retval=0
else $as_nop
  printf "%s\n" "$as_me: failed program was:" >&5
sed 's/^/| /' conftest.$ac_ext >&5

  ac_retval=1
fi
  eval $as_lineno_stack; ${as_lineno_stack:+:} unset as_lineno
  as_fn_set_status $ac_retval

} # ac_fn_c_try_compile

It looks like coreutils 'install' is not tagging files properly - in particular these header files

(thanks to @jshimod for asking me if i had actually tried to compile with that header ;) )

configure.ac has the following:

This turned out to be that the xxhash, zstd, lz4 ports had not been re-built with the latest 'install' from coreutils. Once that was done, the file tags were ok.
