4Subject: [PATCH] realpath.c: Remove trailing slashes
5
6Linux system's realpath() remove trailing slashes, but pseudo's doesn't, need
7make them identical.
8
9E.g., the following code (rel.c) prints '/tmp' with system's realpath, but
10pseudo's realpath prints '/tmp/':
11
12 #include <stdio.h>
13 #include <limits.h>
14 #include <stdlib.h>
15
16 int main() {
17 char out[PATH_MAX];
18 printf("%s\n", realpath("/tmp/", out));
19 return 0;
20 }
21
22$ bitbake base-passwd -cdevshell # For pseudo env
23$ gcc rel.c
24$ ./a.out
25/tmp/ (but should be /tmp)
26
27This patch fixes the problem.
