Description URA Hiroshi 2009-06-23 09:21:56 UTC 
I tried building glibc-2.10.1 with disable-hidden-plt configure option, nscd
failed to link due to the following error:

Comment 1 Ulrich Drepper 2009-06-23 15:12:51 UTC 
Then don't use the option.  This is why the Makefile rules are what they are.
Comment 2 URA Hiroshi 2009-08-25 07:21:15 UTC 
I see, but I need glibc with --disable-hidden-plt.

I found the cause of this link error. The cause is the "atrribute_hidden" in
the declaration of "__nss_next2()" occurres. The link successes by appling
the following patch.
