Summary: configuration script fails at building readline
shared library module
Status: Open
Type: Bug
Package: Compile Failure
Operating System: AIX 5.3 oslevel -r 5300-11
PHP Version: 5.3, 5.4, trunk
Block user comment: N
Private report: N
New Comment:
Basically the problem is that ./configure checks for function 'rl_pending_input', which
happens to be a variable. In AIX variables and functions are exported differently, so the detection
fails.
In Aix, functions and variables are exported differently, which prevents ld from resolving a
variable as a function.
nm -Bgx /usr/local/lib/libreadline.so | grep rl_pending_input # variable
0x20003338 D rl_pending_input
nm -Bgx /usr/local/lib/libreadline.so | grep rl_yank_pop # function
0x10031acc T .rl_yank_pop
0x20003f58 D rl_yank_pop
(So it is only 'D' for variables, both 'T' and 'D' for functions.)

What's in your config.log? I do not mean to paste it all, but I need to see the parts related
to readline and rl_pending_input() in particular. Put config.log online, if possible.
I guess your lib is broken or was built in a wrong way.

Description:
------------
readline shared library 6.0 has been build on aix with gcc 4.2.0, gnu make 3.80, shared library
ncurses 5.7, following a bit the guide at http://www.tekwire.net/joomla/building/apache/http_AIX_5.2.htm#p2.29
Everything seems to be working except that readline.h include file doesn't cope well with php
5.3.2 configure script. After downgrade php to 5.2.6 and patching it for openssl 1.0 everything
works like it should.
excuse my bad english and my less than little knowledge in coding
Expected result:
----------------
Thank you for using PHP.
Actual result:
--------------
checking for libedit readline replacement... no
checking for readline support... yes, shared
checking for tgetent in -lncurses... yes
checking for readline in -lreadline... yes
checking for rl_pending_input in -lreadline... no
configure: error: invalid readline installation detected. Try --with-libedit instead.
