先回一下 yuncore 的 zmk 的問題
試著在 M300 上 run fast cgi
OpenEmbedded 有現成的 recipe
目前 M300 上這兩個 recipe 都有

從 recipe bb file 的描述來看
- fcgi_2.4.0.bb
- FastCGI is a protocol for interfacing interactive programs with a web server.
- spawn-fcgi
- spawn-fcgi is used to spawn FastCGI applications
我應該兩個 recipe 都需要
注意到 /sources/meta-openembedded/meta-webserver 並沒被加到 bblayers
這要修改 conf/bblayers.conf 不然該目錄下的 recipe 都不會被找到
修改如下

mfgtools 燒錄後開機試試
fcgi 提供的是 library 與 header file 讓我們寫的 c code 能 include
library 如下
root@Cellular Router:/usr/lib# ls libfcg* -al
lrwxrwxrwx 1 root root 18 Jan 1 1970 libfcgi++.so.0 -> libfcgi++.so.0.0.0
-rwxr-xr-x 1 root root 12240 Apr 24 02:49 libfcgi++.so.0.0.0
lrwxrwxrwx 1 root root 16 Jan 1 1970 libfcgi.so.0 -> libfcgi.so.0.0.0
-rwxr-xr-x 1 root root 32312 Apr 24 02:49 libfcgi.so.0.0.0
root@Cellular Router:/usr/lib#
header files 不知道在哪裡
spawn-fcgi 是個執行檔 說明如下
root@Cellular Router:~# spawn-fcgi -h
Usage: spawn-fcgi [options] [-- <fcgiapp> [fcgi app arguments]]
spawn-fcgi v1.6.4 (ipv6) - spawns FastCGI processes
Options:
-f <path> filename of the fcgi-application (deprecated; ignored if
<fcgiapp> is given; needs /bin/sh)
-d <directory> chdir to directory before spawning
-a <address> bind to IPv4/IPv6 address (defaults to 0.0.0.0)
-p <port> bind to TCP-port
-s <path> bind to Unix domain socket
-M <mode> change Unix domain socket mode (octal integer, default: allow
read+write for user and group as far as umask allows it)
-C <children> (PHP only) numbers of childs to spawn (default: not setting
the PHP_FCGI_CHILDREN environment variable - PHP defaults to 0)
-F <children> number of children to fork (default 1)
-b <backlog> backlog to allow on the socket (default 1024)
-P <path> name of PID-file for spawned process (ignored in no-fork mode)
-n no fork (for daemontools)
-v show version
-?, -h show this help
(root only)
-c <directory> chroot to directory
-S create socket before chroot() (default is to create the socket
in the chroot)
-u <user> change to user-id
-g <group> change to group-id (default: primary group of user if -u
is given)
-U <user> change Unix domain socket owner to user-id
-G <group> change Unix domain socket group to group-id

耐著性子看一下吧
先試著 build 出第一個範例 - TinyFastCGI
#include "fcgi_stdio.h" /* fcgi library; put it first*/
#include <stdlib.h>
int count;
void initialize(void)
{
count=0;
}
void main(void)
{
/* Initialization. */
initialize();
/* Response loop. */
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_HOSTNAME"));
}
}
