$im = @imagecreatefromjpeg ($imgname); 			    
if ($im==""):
  echo "Error opening $imgname<br>";
else:
  $th_im =  @imagecreate (100, 100);
  $a = imagecopyresampled ($th_im, $im, 0, 0, 0, 0, 100, 100, imagesx($im), imagesy($im));
endif;

header("Content-type: image/jpeg");
imagejpeg ( $th_im );
imagedestroy($im);

Configured php with:
./configure --with-apxs2=/usr/local/apache2/bin/apxs --with-mysql=/usr --with-zlib --with-bz2 --enable-trans-sid --with-mcrypt --enable-exif --with-gd --with-jpeg-dir=/usr/lib

The thing is that I've removed all prior installations of gd from my system, and am using the gd extension packaged with php.  The imagecopyresized function works just fine.

suggestions?

If you configured 4.3.0-pre1 with the argument --with-gd, then PHP does not use the bundled libs. Any version after 4.3.0-pre1 will use the bundled libs by default, unless you specify a path to gd.
Please try to configure 4.3.0-pre1 with the argument --with-gd=php or try a snapshot from http://snaps.php.net and configure with --with-gd.

Also --with-jpeg-dir=/usr/lib is incorrect. Correct option would be --with-jpeg-dir=/usr 

And there's no bug here.

I used '--with-gd=php' as suggested, and the functions:
imagecopyresampled()  and
imagecreatetruecolor()  both do not work.  

If I recall correctly, '--with-gd=php' also complained of a lack of a libgd.(a|so) file as well.

I've tried '--with-jpeg-dir=/usr' and '--with-jpeg-dir=/usr/lib' both.  I don't see any errors associated with the jpeg6b library tho, always gd.

I'm dizzy from the recompiling ;-)  But I'll try again later.  Thanks for the tips guys.

Me again.  Problem fixed, but not solved.

I installed Slackware 8.1 from scratch.  A fresh installation of php-4.3.0pre1 now produces the functions that were missing before using:

rm config.cache; \
./configure \
--with-apxs2=/usr/local/apache2/bin/apxs  \
--with-mysql=/usr \
--with-zlib \
--with-bz2=php \
--enable-trans-sid \
--enable-exif \
--with-gd=php \
--with-jpeg-dir=/usr \
--with-png-dir=/usr 

After making and installing the function:
print_r (get_extension_funcs ("gd"));    
- shows 72 functions.

On my old installation, the same thing produced only 56 functions. (w/ imagecopyresampled() and imagecreatetruecolor() being among the missing 0

So the problem is fixed, but I do not know what was wrong with my OS that made this so difficult.

If anyone has any ideas to solve this, feel free to suggest and I'll check logfiles etc.
