[Samba] readline/termcap problems compiling Samba 3.5.0rc1 on CentOS 5.4 64-bit

[Joe Ammann]

Hi all

When I try to compile  3.5.0rc1 on CentOS 5.4, I get the seemingly well know 
problem below

Linking bin/smbclient
/usr/lib/gcc/x86_64-redhat-linux/4.1.2/../../../../lib64/libreadline.so: undefined reference to `tgetnum'

collect2: ld returned 1 exit status

I googled and read quite a bit, all links seem to suggest that either a missing
readline-devel and/or ncurses-devel might be the cuplrit. Now, I think I got
everything installed:

# rpm -qa --queryformat '%{name}\t%{version}\t%{arch}\n' | egrep '(readline|curses|termcap)' | sort
libtermcap      2.0.8   i386
libtermcap      2.0.8   x86_64
libtermcap-devel        2.0.8   i386
libtermcap-devel        2.0.8   x86_64
ncurses 5.5     i386
ncurses 5.5     x86_64
ncurses-devel   5.5     i386
ncurses-devel   5.5     x86_64
readline        5.1     i386
readline        5.1     x86_64
readline-devel  5.1     i386
readline-devel  5.1     x86_64
termcap 5.5     noarch

A little testprogram fails with the same error, if I do

# gcc -o tt tt.c  -lreadline
/usr/lib/gcc/x86_64-redhat-linux/4.1.2/../../../../lib64/libreadline.so: undefined reference to `PC'
...

But succeeds if I either add -lcurses/-ltermcap or the linker flags that Samba uses 

gcc -o tt tt.c  -Wl,-z,relro -Wl,--as-needed  -Wl,--export-dynamic -lreadline

I checked the Makefile and config.log, it correctly determined the linker
flags to be

TERMLIBS=-lreadline -ltermcap

but still, I can't get rid of the above error. I'm a bit lost, any hints?
