What can you see with following patch: diff --git a/gcc/gcc-ar.c b/gcc/gcc-ar.c index 1155ba83e35..452ca87d2ce 100644 --- a/gcc/gcc-ar.c +++ b/gcc/gcc-ar.c @@ -199,6 +199,8 @@ main (int ac, char **av) /* If the exe_name points to the wrapper, remove folder of the wrapper from prefix and try search again. */ + fprintf (stderr, "exe_name: %s, wrapper_file: %s\n", exe_name, + wrapper_file); if (strcmp (exe_name, wrapper_file) == 0) { char *exe_folder = wrapper_file; It's probably related to lrealpath that does not follow links. Btw. is your link a mount? I'm tending to remove the whole smartness of gcc-ar that removes the prefix. Martin
