回复 #6 HonestQiao 的帖子
麻烦你帮我看看这样做正确不:
1 进入php5.3.0/ext目录, 执行:
./ext_skel --extname=vehicles
2 修改.cc及.h文件:
php_vehicles.h:
- #ifndef PHP_VEHICLES_H
- #define PHP_VEHICLES_H
- #define PHP_VEHICLES_EXTNAME "vehicles"
- #define PHP_VEHICLES_EXTVER "0.1"
- #ifdef HAVE_CONFIG_H
- #include "config.h"
- #endif
- extern "C" {
- #include "php.h"
- }
- extern zend_module_entry vehicles_module_entry;
- #define phpext_vehicles_ptr &vehicles_module_entry;
- #endif /* PHP_VEHICLES_H */
vehicles.cc:
- #include "php_vehicles.h"
- #include "car.h"
- #include <iostream>
- using namespace std;
- zend_object_handlers car_object_handlers;
- zend_class_entry *car_ce;
- struct car_object {

- }

- {
- zval *tmp;
- zend_object_value retval;
- car_object *obj = (car_object *)emalloc(sizeof(car_object));
- memset(obj, 0, sizeof(car_object));
- obj->std.ce = type;
- ALLOC_HASHTABLE(obj->std.properties);
- zend_hash_init(obj->std.properties, 0, NULL, ZVAL_PTR_DTOR, 0);

- car->accelerate();
- }
- }
- PHP_METHOD(Car, brake)
- {
- }
- PHP_METHOD(Car, getCurrentSpeed)
- {
- Car *car;
- car_object *obj = (car_object *)zend_object_store_get_object(
- getThis() TSRMLS_CC);
- car = obj->car;
- if (car != NULL) {

- return SUCCESS;

- speed -= (5 * this->getCurrentGear());
- }
- int Car::getCurrentSpeed() {
- return speed;
- }
- int Car::getCurrentGear() {
- return currentGear;
- }
3 修改config.m4文件:
config.m4:
- PHP_ARG_ENABLE(vehicles,
- [Whether to enable the "vehicles" extension],
- [ --enable-vehicles Enable "vehicles" extension support])
- if test $PHP_VEHICLES != "no"; then
- PHP_REQUIRE_CXX()
- PHP_SUBST(VEHICLES_SHARED_LIBADD)
- PHP_ADD_LIBRARY(stdc++, 1, VEHICLES_SHARED_LIBADD)
- PHP_NEW_EXTENSION(vehicles, vehicles.cc car.cc, $ext_shared)
- fi
4 phpize
5 ./configure --enable-vehicles
6 make
在这里编译过了, 但有几个warnning, 关于char*类型转换的. 不会因为几个warnning的问题吧??
7 make install
nstalling shared extensions: /usr/local/lib/php/extensions/no-debug-non-zts-20090626/
8 我把刚才编译的vehicles整个目录copy到/var/www/下.
9 修改php.ini:
emacs /etc/php5/apache2/php.ini
在里面加入extension=vehicles, 并把 enable_dl设置为On
10 重启apache2
11 在浏览器里输入http://localhost/vehicles/vehicles.php出现以下错误:
Warning: dl() [function.dl]: vehicles: Unable to initialize module Module compiled with module API=20090626, debug=0, thread-safety=0 PHP compiled with module API=20060613, debug=0, thread-safety=0 These options need to match in /var/www/vehicles/vehicles.php on line 5
Functions available in the test extension:
Warning: Invalid argument supplied for foreach() in /var/www/vehicles/vehicles.php on line 10
Module vehicles is not compiled into PHP
网上找了很多资料都没说这个问题, 我该怎么解决? |
