i tried elgg 1.8.0.1 on windows XP and it installed successfully but when i tried on fedora 12 it is not able to install. here is what happens i extracted the zip file for elgg 1.8.0.1 in /var/www/html now when i use firefox to go to the url http://localhost/elgg-1.8.0.1 it asks me whether i want to open or save install.php ,but when i open it with a text editor or if i save it and then open it its an empty file. The size of file is 0 bytes. And when i use Konqueror to do the above it displays a timeout error instantly(at the moment i press enter).

i checked the error log of apache and it displays the following line

child pid 2147 exit signal Segmentation Fault(11)

I was able to install elgg 1.7.11 on fedora successfully,also i am able to run other php files nicely.I wonder what can go wrong *because elgg 1.8.0.1 installs successfully in windows XP. (Note:I have the appropriate permissions for reading writing and executing scripts in the elgg 1.8.0.1 directory)

UPDATE: i tried strace php install.php and i got a long trace of which i am only showing the last few lines 

mmap2(NULL, 11905, PROT_READ, MAP_SHARED, 3, 0) = 0xb77cb000
munmap(0xb77cb000, 11905)               = 0
close(3)                                = 0
getdents(4, /* 0 entries */, 32768)     = 0
time(NULL)                              = 1317422887

access("/usr/share/zoneinfo/Asia/Calcutta", R_OK) = 0

access("/var/www/html/elgg-1.8.0.1/engine/settings.php", R_OK) = -1 ENOENT (No such file or directory)
--- SIGSEGV (Segmentation fault) @ 0 (0) ---
+++ killed by SIGSEGV (core dumped) +++
Segmentation fault (core dumped)

Now any idea why there is this segmentation fault? I have read that infinite recursive function calls can cause seg faults but if that was the problem it wouldnt have run on windows. If i try to include a lot of files with include or require or require_once can it lead to php causing a segmentation fault?

  • This sounds like there may be an issue with `mod_php`. Can you try creating a test PHP file with the contents, ``? When you access it from your browser, what happens? – Andrew M. Sep 12 '11 at 04:20
  • @Redmumba yes i can create other php files and they are working correctly.As my question says i was able to successfully install elgg 1.7.11. – lovesh Sep 14 '11 at 09:53
  • My bad, I am blind! :) Just out of curiosity, have you tried doing something like executing it from the command line (i.e., `php install.php`)? Also, have you enabled PHP logging in your `php.ini`? – Andrew M. Sep 15 '11 at 21:43
  • @Redmumba yes i have enabled logging and updated my question to show the errors.Thanks – lovesh Sep 20 '11 at 18:13
  • The superglobal notices have nothing to do with the segfault; the $_SERVER array is unavailable when running the CLI. Which database engine are you using? – xofer Sep 20 '11 at 18:22
  • @fuscata i am using mysql 5.1.4 – lovesh Sep 20 '11 at 18:25
  • any chance you have mhash PHP module installed? Any clues in the event log viewer? – xofer Sep 20 '11 at 18:38
  • @fuscata i cant find the `mhash` php module in both my linux `php.ini` file as well as windows `php.ini` file. Where can i find the event log viewer? – lovesh Sep 20 '11 at 18:59
  • Control Panel > Administrative Tools > Event Viewer or Run > eventvwr – xofer Sep 20 '11 at 21:33
  • @fuscata elgg is installed successfully on windows. i am facing this problem on linux(fedora 12) – lovesh Sep 21 '11 at 05:39
  • Ah ok my mistake. Could you try: create another file in the same directory as index.php, called say `test.php` with only 1 line: ` – xofer Sep 21 '11 at 12:51

  • I saw the _"core dumped"_. You should debug it with gdb and send `bt full` infos to elgg's developers. – quanta Oct 01 '11 at 11:11

There was a bug in my php version. Updating to a later version solved the issue.
