I downloaded php-4.3.10 off http://www.php.net/ and am trying to build a
simple helloworld extension.

I ran ext_skel, modified config.m4 where it had the PHP_ARG_ENABLE line:

PHP_ARG_ENABLE(foo, whether to enable foo support,
dnl Make sure that the comment is aligned:
[ --enable-foo Enable foo support])

I followed the remaining steps too, (./buildconf --force, ./configure
--with-foo, make)

Now when I say
../sapi/cli/php -f ext/foo/foo.php

I get this error:

Warning: dl(): Unable to load dynamic library
'/usr/local/lib/php/extensions/no-debug-non-zts-20020429/foo.so' -
/usr/local/lib/php/extensions/no-debug-non-zts-20020429/foo.so: cannot
open shared object file: No such file or directory in
/home/deep/php-4.3.10/ext/foo/foo.php on line 3
Functions available in the test extension:<br>

Warning: Invalid argument supplied for foreach() in
/home/deep/php-4.3.10/ext/foo/foo.php on line 8
<br>
Module foo is not compiled into PHP
[deep@deepak-linux php-4.3.10]$

I tried in vain to look up the Web for solutions, but to no avail.

Could anyone help me please?

Thanks,
Deepak
