compiling ezmlm on centos 5.x (tls errors and more)

getting killed by:

usr/bin/ld: errno: TLS definition in /lib/libc.so.6 section .tbss mismatches non-TLS reference in substdio.a(substdo.o)
/lib/libc.so.6: could not read symbols: Bad value

?

phew…

man…

ok, here’s how to get this crap to compile:

untar it, etc
cd to the dir

then:

echo gcc -O2 -include /usr/include/errno.h > conf-cc
echo cc -m32 -O2 -include /usr/include/errno.h >> conf-cc
echo cc -m32 >conf-ld

(these are just files in the current dir)

add :

#include “log.h”

to :

ezmlm-manage.c

and

ezmlm-return.c

(thanks to: http://lists.freebsd.org/pipermail/freebsd-ports-bugs/2003-August/009785.html for that little tidbit)

make

it should work

This fixes the following errors:

ezmlm-manage.c: In function âmainâ:

MySQL 5 Left Joins not working – CodingForums.com

Mysql Upgrade – left joins not working?

If you are getting an error like:

Unknown column ‘i.blah’ in ‘on clause’

using a left join like:

FROM items_table AS items, meta_data_table AS md, categories_table AS cat LEFT JOIN restricted_table AS rst ON items.item_id=rst.item_id WHERE items.title LIKE ‘the%’

switch the order of the from around so that the item MySQL is complaining about is at the end of the from clause. That should fix it in many cases.

replacing with newlines in emacs

Wow, learned how to do something in emacs that I’ve wanted to do for probably 10 years now.

Replace text with newlines. Here’s how:

when in replace mode, press control-q control-j to insert the newline.

I used replace:

<pre>
on><op></op></pre>

with

<pre>
on>control-q control-j<op></op></pre>

it to fix this ugly html:

<pre>
linux rockslinux rocks the casbahlinux is rad
</pre>

with this:

<blockquote><pre>
linux rocks
linux rocks the casbah
linux is rad
</pre></blockquote>

Of course in real life I had about 50 options I would have had to edit by hand to make it all pretty.

cybersource and umlauts (php api)

Don’t be surprised if cybersource’s php api craps out when calling cybs_run_transaction with any umlauts in the input (card holder name, etc.)

For me I get:

Aborted.

Fun.

converting an entire mysql server to not use isam files

So you’ve got a mysql server with an unknown number of isam tables and you need to convert them (the easy way)? Here’s how:

find /var/lib/mysql/ -name “*.ISM” -print > convert.txt

emacs convert.txt

replace: “/var/lib/mysql/” with “alter table “

replace “.ISM” with ” type = myisam;”

replace “/” with “.”

Be careful to include the spaces where I have them.

The run:

mysql -u root -p < convert.txt

How to modify return-path header in php mail function

Normally the return path is set by sendmail (or whatever the server is running, qmail, etc.)

However you can pass a fifth argument to php’s mail function to reset it to what you want. Here’s an example:

$result = mail($to, $subject, $body, “From: $from\n”, “-f$from”);

make sure you do not put a newline in after the fifth argument’s from. php will error out.
