I believe something changed in the GD library where lo-res internal images
were not promoted to hi-res or something like that...

This could be the same thing.
Or not.
Try ./configure --without-mbstring
Unfortunately I'm deliberately enabling mbstring because I need
multibyte string support, along with mbregex... If I could live
without these extensions I wouldn't need to recompile.
I just tried compiling on a clean install of 10.4, with a clean
install of fink (I'm using some fink packages like apache2, JPEG,
PNG, etc) and I'm still getting the ld problem I mentioned. Think I
may have to report it as a bug and see what comes of that.

A little perseverance always helps... I went through my configure
command and removed a few possibly obsolete directives. I then ran
into a dependency on gdbm that I can't explain, but after adding that
in, I'm happy to report that it now works. For the record, here's my
working config while building PHP 5.0.4 on OS X 10.4.1 as an
apache2handler using fink libraries, also notable is that it also
enables both mysql and mysqli extensions simultaneously:

hi
i am new to php and am building my first php extension. i have a code
in cpp that uses pthreads for carrying out the job. i tried to convert
this into a php extension but was unable to do so despite a number of
tries.
i am able to compile the extension that i build but am unable to load it.
the error that i get is ::
PHP Warning: Unknown(): Unable to load dynamic library
'/home/y/lib/php/20020429/perfext.so' -
/home/y/lib/php/20020429/perfext.so: Undefined symbol
"pthread_exit" in Unknown on line 0
i have used the line
PHP_ADD_LIBRARY_WITH PATH to include pthread library and also used
-pthread in the cppflags.
do i need to do anything else for creating such an extension.

Thanks! You're right, that looks pretty straight forward. Although I
do have two additional questions...
How do I find out how my PHP was compiled? The documentation states:
You have to compile PHP with the option --with-oracle[=DIR], where
DIR defaults to your environment variable ORACLE_HOME.
But I'm using PHP from the Red Hat default install (I didn't compile it).
Also, do you know if this is Oracle version independent. More
specifically will this work with Oracle 10g?
Thanks

To find out how your PHP was compiled create a test page with this
only...
<?php
phpinfo();
?>
And then load the page from your web server. It will return a wealth of
information to you. As far as Oracle compatability it would be hard to
know with the info you provided, but you'll find out things like PHP
version when you do the test page.

Thanks! So it looks like PHP wasn't compiled with the needed variable.

That is incredibly interesting stuff, many thanks for that link! So the

No.
Richard, did you actually go to the site that Greg showed and look at
the example? Two very different (as in content) postscript documents...
same MD5 hash.
I actually tried it out for myself... and indeed the two different
documents produced the exact same MD5 sum.
That's a one in a billion chance...
So, if your binary file HAPPENS to match that meaningless string, you
could use that OTHER meaningless string instead...
Again I say... did you look at the other "meaningless" string in the
example? I don't pretend to understand how the authors made it work,
but it wasn't just some "meaningless" string that they got to match.
I'll bet neither of the two strings has any real-world "meaning"
They just happen to be the two strings that are "easy" to find that have
the same MD5.
This has absolutely NO meaning in real-world uses of MD5.
You'd have heard a LOT more screaming and wailing and gnashing of teeth if
this mattered. :-)
Unless of course most people dismiss it the same way that you seem to be
dismissing it. ;)

Hello,
Recently with the help of several of you I got a script working. It's
complex, I'm still new, some parts of it came from other authors and I
adapted it, and generally despite the fact that it seems to work
perfectly at this point, I am certain that there is bloat, repetition
and simply useless crap.
I'd like to know if anyone can have a look and help me optimize what I
have. For example, there are several mysql queries - would it be
possible to combine them somehow? I use the image upload section twice
because I couldn't figure out how to make it work using different vars
within the same section. That kind of newbie stuff.
The code is here: http://hashphp.org/pastebin.php?pid=3701
Thanks in advance!

Hey there Jackson,
The first thing I would consider would be to see if you can classify
the code into chunks that do a certain job, and then rewrite them as
functions. I would also consider looping through arrays for repetitive
jobs (lines 258 -> 270 for example).
Down the line you could consider the use of classes, your own or ready
made - such as the ever useful PEAR (http://pear.php.net). I
personally found that the greatest saver of time to be the re-use of
code that I know works well for given situations.
