Just wondering if this should work, to get the php 5.1.2 on FC 5 debugging working ?

It does nothing at the moment.

Greetings

What debugger version do you use? 2.16.20?

Hi Dmitrie,

2.16.20 only has support till php 5.0.4.
The free version 2.11.32 does all php version.

The webserver I use has php 5.1.1
My development (fc5) has 5.1.2

Since the free version supports those version, I compiled dbg.so 2.11.13. When I start debugging, I only get an errormessage something is wrong, but I cannot find something in the http/php error logs. If I use dbg 2.18, phped tells me I have to use the 2.16.

I just wanted to know if it is possible to use the 2.11 version with phped 3.3.3 on linux.
Or is this just impossible.

Since the 4.x upgrade for linux is not something for tomorrow, I thought this could be a good temporary solution.

I just want the 5.1 version support because I'm doing almost everything a bit OO oriented, and there is better support for it in the 5.1 versions.

Or should the dbg 2.16.20 for php 5.0.4 be used, and will it work for almost 95 %. (Should be fine for me pto debug).

BTW whatever version I use, phpinfo shows the correct information.

I hope I didnt confuse you too much.

Greeting

Johan

I just tested the 2.16.20 dbg.

I got this error :
[07-Apr-2006 09:39:25] PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php/modules/dbg.so-5.0.4' - /usr/lib/php/modules/dbg.so-5.0.4: undefined symbol: _zval_dtor in Unknown on line 0

If you like I can send the phpinfo output of the default FC5 php installation.

Greatings

Johan

updated debugger modules will be available to all customers who purchased phped for linux. Check your account

Hi Dmitrie,

Got it, but still has no success in debugging. I did get the folowing error, and it seems the default php.ini file is changed. So I follwed the solution as given in [url]http://forum.nusphere.com/viewtopic.php?t=1657&highlight=lookup+failed[/url]

- Setting the host in setting->tools>debugger to localhost did work, until stepping through the code. The output is empty, so I assume connection to dbg is working.
( F7/F8 does not step through the code, just ends the debug session)

- This is what the http_error_log file generates when I press F7/F8 :

[quote][Fri Apr 07 15:36:17 2006] [notice] child pid 5045 exit signal Segmentation fault (11)[/quote]
and the ps command just before this gives :

Looks not so good.

Hi dmitrie

Just downgraded to 2.0.54/5.1.2

Same result Dbg crashes.
I'm now looking how to add debugging information from httpd.

Greetings

I hope you can make something from this.

Greetings

Jo

thanks for the back trace.
It's clear that it's Zend crashed:
#0 zend_assign_to_variable() in /usr/src/debug/php-5.1.2/Zend/zend_execute.c
execution reached this point from Apache and DBG is not involved anyways.

I'd recommend you submit bug in http://bugs.php.net/
They will be happy to see backtrace too.


BTW, before proceeding with it, just cleanup php.ini from any and all php extension (see extension=) and from Zend extension (zend_extension=) entries, restart apache (stop-start) and check if it helped.

Hi dmitirie,

No matter waht i enable/disable, always segfaults.

I discovered that everytjing seems to work until I do get to the first variable assignment.

I will compile httpd and php from scratch and see what this gives with differnet php versions.
Everything works if i does not use the debugger.

Any hints ?

Johan

Hi dmitire,

It keeps on crashing, no matter what I do. So i compiled with debug info hoping to retrieve more detailed info.

Because I enabled debug for php.

PHP Warning: PHP Startup: dbg: Unable to initialize module
Module compiled with module API=20050922, debug=0, thread-safety=0
PHP compiled with module API=20050922, debug=1, thread-safety=0
These options need to match

Could you assist in this (if possible)?

Apache 2.0.55
PHP 5.1.2

Thanks
