Embed SAPI

["Jon" <jon@xxxxxxxxxxxx>]

I'm having a few problems using the embed sapi. I've compiled PHP with 
the -enable-embed option (not with the static option) and everything 
compiled ok. The contents of my sapi lib dir is as follows:

cphp # ls /usr/lib/php5/include/php/sapi/embed/
CREDITS               config.m4    php5embed.dsp  php_embed.h
EXPERIMENTAL  config.w32  php_embed.c

My C code trying to use the sapi is as follows:

#include <php_embed.h>

int main(int argc, char *argv[])
{
   PHP_EMBED_START_BLOCK(argc, argv)
       zend_eval_string("echo 'Hello World!';", NULL,
                        "Simple Hello World App" TSRMLS_CC);
   PHP_EMBED_END_BLOCK()
   return 0;
}

My GCC command trying to compile it as follows:

gcc
  -I/usr/lib/php5/include/php \
  -I/usr/lib/php5/include/php/main \
  -I/usr/lib/php5/include/php/Zend \
  -I/usr/lib/php5/include/php/TSRM \
  -I/usr/lib/php5/include/php/sapi \
  -I/usr/lib/php5/include/php/sapi/embed \
  -Wall -g
embed.c

I have tried linking this, passing -c to make a .o file then linking but 
nothing helps. I always get the following errors:

/tmp/ccORuj71.o: In function `main':
/home/crisp/cphp/embed.c:5: undefined reference to `php_embed_init'
/home/crisp/cphp/embed.c:5: undefined reference to `executor_globals'

/home/crisp/cphp/embed.c:8: undefined reference to `php_embed_shutdown'
collect2: ld returned 1 exit status
make: *** [all] Error 1

Now I know this SAPI is 'experimental' but many others seem to be able to 
use it fine. Any help would be much appreciated. Just incase you need to 
know I'm running Gentoo Linux but I compiled PHP manually aswell as emerging 
it with a hack to allow the embed USE flag. Neither show any different 
results. I also compiled manually using the following options:
../configure --with-curl --with-curlwrappers --enable-exif --with-gd --enable-ftp 
 --with-imap --with-mysql --with-mhash --with-ncurses --enable-sockets --with-readline 
--enable-pcntl --with-mcrypt --enable-debug --enable-embed --with-mhash --with-mysqli 
--with-openssl --with-imap-ssl

Thanks in advance, and sorry for so much copying and pasting :p
