If you are experiencing “segmentation fault” when trying to do a PEAR package install on a system using Midgard CMS, do the following.

• Comment out “extension=midgard.so” line in php.ini.
• Restart Apache HTTP Server.
• Re-run Pear package install (i.e. pear install Mail).
• Uncomment out “extension=midgard.so” line in php.ini.
• Restart Apache HTTP Server.

If you experience the following error that refers to mailtemplate or mailmime, this means you don’t have PEAR Mail or PEAR Mail_mime package installed. For example after you have downloaded the PEAR package to install PEAR Mail package type at the shell prompt without quotes “pear install Mail”.

Example of error messages
Warning: main(Mail.php): failed to open stream: No such file or directory in
/usr/share/pear/midcom/lib/midcom/helper/mailtemplate.php on line 17

Fatal error: main(): Failed opening required ‘Mail.php’
(include_path=’.:/usr/local/share/php/pear’) in
/usr/share/pear/midcom/lib/midcom/helper/mailtemplate.php on line 17

I was having some problems with my web site so I went off to check my Apache HTTPD error_log and found three warning messages logged.

Apache HTTPD error_log
/usr/sbin/httpd:/usr/lib/apache/modules/libphp4.so: /usr/local/lib/libmysqlclient.so.12.0 : WARNING: symbol(client_errors) size mismatch, relink your program
/usr/sbin/httpd:/usr/lib/apache/modules/libphp4.so: /usr/local/lib/libmysqlclient.so.12.0 : WARNING: symbol(default_directories) size mismatch, relink your program
/usr/sbin/httpd:/usr/lib/apache/modules/libphp4.so: /usr/local/lib/libmysqlclient.so.12.0 : WARNING: symbol(globerrs) size mismatch, relink your program

After some time of research and with no solution, I decided to mention the problem in Midgard IRC channel. With Piotras comment, I quote “TheWarden: php was compiled with different version of mysql libraries”. So with that said off I went to re-install PHP v4.3.11 but this time configure it with –with-mysql=/usr/local so the correct MySQL libraries would be used. If –with-mysql is not used PHP will use it’s own built in MySQL libraries. I double checked my Apache HTTPD error_log and now the warnings are no longer present.

I recently installed PHP 4.3.11 from source (due to configuration requirements) on to an OpenBSD i386 v3.7 server. The installation went perfectly as it has many times before, however I found out that the PEAR script was not installed (normally in /usr/local/bin). I discovered this when trying to install some pear packages doing “pear install packagename”. I get a returned error of “-bash: pear: command not found”. I tried locating the PEAR script using “find / -name pear” and “/usr/libexec/locate.updatedb” then “locate -i pear”. The result came up empty with no PEAR script in the returned results. I double checked the PEAR documents, PHP documents and ./configure all three places stated PEAR is installed by default unless a parameter is provided at configure with –without-pear. I’m still not aware as to why the PEAR script was not installed however with help by SmallOne of #midgard I was able to resolve the problem manually. Here’s how it was resolved at the shell prompt.

• # cp pear.sh /usr/local/bin/pear
• # chmod 755 /usr/local/bin/pear

If anyone knows how the PEAR script could not have been installed please let me know, thanks.

I was today surfing on the net for some UNIX/BSD flash bootable operating system, and some how, one link took me to another link and to another one and I ended reading about The GPL license. Not the context it self but about the ” virus effect ” that is has, that kill all other software. I ended up reading all what Martin Cracauer has to say about the GPL and it side effects. I believe it worth for you all to read it.
