how do you create extension dll (using VC++6.0)

sbworld

i want to make extension module with dll that implement unzip function..
so i searched here http://www.zend.com/apidoc/ <----Extending php 4.0
it says make example_module.c and examle_module.h with this source code
and include all php source code and complie it

but when i tried it i got several errors to build..

i've downloaded php version 4.3.1 source code and unzipped.
and compiled but it said

---> 'Cannot open include file: 'zend_config.h': No such file or directory'

so i downloaded that file and compiled but it said

---> 'Cannot open include file: '../main/php_config.h': No such file or
directory'

so changed that file '../main/php_config.h.in' and another problem

---> is 'Cannot open strings.h'

so downloaded that file and complied

but 102 errors....

---> extern void string_load (file ) ;
---> syntax error : missing ')' before '' etc

what was i wrong?

is there any different way to create extention dll using VC++ 6.0?

<< ----- source code --------- >>

/ include standard header /
#include "php.h"

/ declaration of functions to be exported /
ZEND_FUNCTION(first_module);

/ compiled function list so Zend knows what's in this module /
zend_function_entry firstmod_functions[] =
{
ZEND_FE(first_module, NULL)
{NULL, NULL, NULL}
};

/ compiled module information /
zend_module_entry firstmod_module_entry =
{
STANDARD_MODULE_HEADER,
"First Module",
firstmod_functions,
NULL,
NULL,
NULL,
NULL,
NULL,
NO_VERSION_YET,
STANDARD_MODULE_PROPERTIES
};

/ implement standard "stub" routine to introduce ourselves to Zend /
#if COMPILE_DL_FIRST_MODULE
ZEND_GET_MODULE(firstmod)
#endif

/ implement function that is meant to be made available to PHP /
ZEND_FUNCTION(first_module)
{
long parameter;

if (zend_parse_parameters(ZEND_NUM_ARGS() TSRMLS_CC, "l", &parameter) ==

FAILURE) {
return;
}

RETURN_LONG(parameter);

}
