lighttpd配置fastcgi出现Internal Server Error

[漂泊的浮萍]

各位大哥，小弟写了一个简单的fastcgi放到lighttpd下面运行，然后出现“500 - Internal Server Error”不知道怎么回事？
以下是代码

#include <fcgi_stdio.h>
#include <stdio.h>

int main() {
	int count = 0;
	while (FCGI_Accept() >= 0) {
		printf("Content-type: text/html\r\n"
				"\r\n"
				"<title>FastCGI Hello! (C, fcgi_stdio library)</title>"
				"<h1>FastCGI Hello! (C, fcgi_stdio library)</h1>"
				"Request number %d running on host <i>%s</i>\n", ++count,
				getenv("SERVER_NAME"));
	}
}

CC = gcc
CXX = g++
libtool = ./libtool

all: main.fcgi

main.fcgi:main.lo
	$(libtool) --mode=link $(CC) -o $@ $^ -lfcgi
	
main.lo:
	$(libtool) --mode=compile $(CC) -c main.c
	
clean:
	rm -rf *.lo  *.o main.fcgi

下面是lighttpd的配置

fastcgi.debug = 1
fastcgi.server = (
    ".fcgi" => (
     "local" => (
      "socket" => socket_dir + "/fcgitest-fcgi.socket",
      "checklocal" => "disable",
      "bin-path" => server_root + "/cgi-bin/main.fcgi",
      "idle-timeout" => 10,
      "min-procs" => 1,
      "max-procs" => 1,
	  "docroot" => server_root + "/cgi-bin"
     )
    )
)

运行之后main.fcgi,进程起来了，但是访问出现500 - Internal Server Error

郁闷了，又好了。 代码什么都没动 500 - Internal Server Error 这个错误一般是服务器的代码有问题
