I added the following line for debugging after

AC_SEARCH_LIBS(gethostbyname, nsl)
AC_MSG_NOTICE([============>> LIBS=$LIBS])

Result: -lnsl was not added to $LIB. $LIB was empty here.

Maybe it's a problem with gethostbyname. Isn't gethostbyname a part of
libc? What would happens if gethostbyname is resolved with libc?

In the manual (thanks for the link, I am a newbie to autoconf):

"first with no libraries" ... so what happens if gethostbyname is
resolved without libnsl? It won't be added :-(

Yes, clear.

I use Linux with:

gcc (GCC) 3.4.6

Kind regards
