#48608 [Fbk->Opn]: Too-old version of libreadline is not detected during ./configure

ID: 48608 User updated by: shahar dot e at zend dot com Reported By: shahar dot e at zend dot com -Status: Feedback +Status: Open Bug Type: Readline related Operating System: Mac OS X 10.5 PHP Version: 5.3CVS-2009-06-19 (snap) Assigned To: jani New Comment: Yes, using --with-libedit compiles and works as expected Previous Comments: ------------------------------------------------------------------------ [2009-08-03 15:09:11] jani@php.net One more question: Without installing anything extra, does using --with-libedit instead work..? As that should be installed there.. ------------------------------------------------------------------------ [2009-08-03 14:39:30] shahar dot e at zend dot com From what I've seen there's a bunch of missing symbols - since I assumed it's a version issue I added a check for just one, but given what we know now, it might be wiser to check for more stuff. 'make' complains about these symbols: 'rl_mark', 'rl_done', 'rl_pending_input' ------------------------------------------------------------------------ [2009-08-03 13:10:19] jani@php.net How nice of Apple. Why don't they use libedit? :) Is the missing rl_pending_input symbol really the only difference? ------------------------------------------------------------------------ [2009-08-03 13:04:12] shahar dot e at zend dot com Thanks for looking into this. I am not entirely sure how to check this, but looking at an include/readline/readline.h that works, I see: #define RL_READLINE_VERSION 0x0600 /* Readline 6.0 */ While on the one that doesn't work, I see: #define RL_READLINE_VERSION 0x0402 So I'm assuming that's readline 4.02 and not 4.2 as I thought before. Then again, according to this discussion: http://discussions.apple.com/message.jspa?messageID=7387944 - it seems that libreadline provided with OS X 10.5 is not really libreadline, but just a not-fully compatible wrapper. If this is true, it is probably a good idea to check for those symbols anyway to avoid this problem on Mac OS X (but perhaps change the error message I added in my patch). Shahar. ------------------------------------------------------------------------ [2009-08-03 11:04:02] jani@php.net Exactly what readline version is it? I tested with 4.2 and it compiles just fine. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
