php5调用外部C库,急!
---------外部c函数 hello.c----------
#include
#include
#include
#include
#include
int hello_cc(char * dbg)
{
  syslog(LOG_DEBUG, "hello_cc %s\n", dbg);
  if(dbg==NULL) return -1;
  if(strlen(dbg)>1024) return -1;
  printf("%s\n", dbg);
  syslog(LOG_DEBUG, "hello_CC return\n");
  return 0;
}
---------php5扩展函数 hello.c-----------
const zend_function_entry hello_functions[] = {
  PHP_FE(confirm_hello_compiled, NULL) /* For testing, remove later. */
  PHP_FE(hello, NULL)
  PHP_FE_END /* Must be the last line in hello_functions[] */
};
PHP_FUNCTION(confirm_hello_compiled)  
{
  char *arg = NULL;
  int arg_len, len;
  char *strg;

  if (zend_parse_parameters(ZEND_NUM_ARGS() TSRMLS_CC, "s", &arg, &arg_len) == FAILURE) {
  return;
  }

  len = spprintf(&strg, 0, "Congratulations! You have successfully modified ext/%.78s/config.m4. Module %.78s is now compiled into PHP.", "hello", arg$
  RETURN_STRINGL(strg, len, 0);  
}
PHP_FUNCTION(hello){
  char *dbg = NULL;  
  int dbg_len, len;
  int result;  

  if(zend_parse_parameters(ZEND_NUM_ARGS() TSRMLS_CC, "s", &dbg, &dbg_len) == FAILURE){
  return;
  }
  res_cc = hello_cc(dbg);
  RETURN_LONG(res_cc);
}
------------php5 调用-------------
if (!extension_loaded("hello")) {
print "skip";
} else {
//dl('hello.so'); //php5中dl()被屏蔽,直接在php.ini中添加hello.so
echo hello("ssssssssqqqqqqqqqqqq");
}

//输出-->> 空白页,估计崩掉了。
求解正确的 PHP_FUNCTION(hello) ,急用!!!

------解决方案--------------------
如果 hello_cc 定义没有错误的话,放在一起编译就可以了

不过你在 hello_cc 中直接 printf 似违反了 php 扩展的约定了吧
