C++ Header file inclusion

I am new to coding PHP extensions. And i was tryin the following snippet in a .cpp file

#include <iostream>
#include "Zend/zend.h"

using namespace std;

void describe_zval(zval *foo)
{
    if (foo->type == IS_NULL)
    {
        php_printf("The variable is NULL");
    }
    else
    {
        php_printf("The variable is of type %d", foo->type);
    }
}

int main(void)
{
    return 0;
}

The variable zval (which is a struct )is present in /usr/local/src/php-5.4.11/Zend/zend.h

Compilation 

g++ -I /usr/local/src/php-5.4.11 -I /usr/local/src/php-5.4.11/Zend try.cpp

This gives the error 

In file included from /usr/local/src/php-5.4.11/Zend/zend_alloc.h:27:0,
                 from /usr/local/src/php-5.4.11/Zend/zend.h:237,
                 from try.c:2:
/usr/local/src/php-5.4.11/Zend/../TSRM/TSRM.h:20:26: fatal error: tsrm_config.h: No such file or directory
compilation terminated.

tsrm_config.h is present in /usr/local/src/php-5.4.11/

How do i include the subdirectories under /usr/local/src/php-5.4.11/ since the compilation process requires many files located in several subdirectories of /usr/local/src/php-5.4.11/

In the php-5.4.11 directory, you should also include Zend, main, TSRM (if you want to develop your extension on a thread-safe server). I mean you should have:-I /usr/local/src/php-5.4.11/main I /usr/local/src/php-5.4.11/Zend I /usr/local/src/php-5.4.11/TSRM, you can create a makefile for including these directories. By the way, why don't you use SWIG for creating your wrapper code? you should try that.
