Hi, Am building a C extension, which is a wrapper to a third party product. I have the basics working, but wanted to use a different call (from PHP) for a number of functions.
So I have a standard PHP C function, and a number of dirreent wrappers depending on what we need.... so:

static void php_main_php_function(INTERNAL_FUNCTION_PARAMETERS, long nType, int expected_args){
 .....
  call main C function();
  Return to PHP
}

PHP_FUNCTION(main_function_wrap_1){
	php_main_php_function(INTERNAL_FUNCTION_PARAM_PASSTHRU, 0,1);
}

PHP_FUNCTION(main_function_wrap_2){
	php_main_php_function(INTERNAL_FUNCTION_PARAM_PASSTHRU, 2,1);
}
-----------------------------
When I call main_function_wrap_1() (or _2()) I get a:
 'php: symbol lookup error: .....undefined symbol: php_main_php_function  

I have tried to do thios as per the mysql drivers, and can't see the differemce between my code, and what they are doing? Anyone any ideas please?

TIA
