移植goahead 3.6.5到Linux

https://blog.csdn.net/richu123/article/details/78112941

 

 

 

一、下载源码
    官网:http://embedthis.com/

二、解压编译
# tar -zxvf goahead-3.6.4.tar.gz
# cd goahead-3.6.4
# make CC=arm-linux-gcc ARCH=arm或(configure && make)
编译完成后进入linux-arm-default/bin生成可执行文件

三、拷贝文件
将bin目录下的可执行文件goahead,库文件libgo.so拷贝到开发板
    库文件可与goahead文件放在同一目录下,也可拷贝到开发板/lib 目录下

四、问题(红色为我遇到的问题)

问题一(运行错误):
goahead: 0: Can't get host address for host dvr: errno 110
goahead: 0: Can't initialize server. Exiting. 

解决办法:修改 /usr/src/goahead-3.1.3-0/src/http.c
# vi src/http.c      // 共有2处相同的代码需修改
=============================================================================
if ((hp = gethostbyname(host)) == NULL) {
    error("Can't get host address for host %s: errno %d", host, errno);
    return -1;
}
memcpy((char*) &intaddr, (char *) hp->h_addr_list[0], (size_t) hp->h_length);
ddr = inet_ntoa(intaddr);
websSetIpAddr(ipaddr);
websSetHost(ipaddr);
=============================================================================

改为:
=============================================================================
#if 0
    if ((hp = gethostbyname(host)) == NULL) {
        error("Can't get host address for host %s: errno %d", host, errno);
        return -1;
    }
    memcpy((char*) &intaddr, (char *) hp->h_addr[0], (size_t) hp->h_length);
    ipaddr = inet_ntoa(intaddr);
#else
    int sockfd;
    struct sockaddr_in sin;
    struct ifreq ifr;
    sockfd = socket(AF_INET, SOCK_DGRAM, 0);
    if (sockfd == -1)
    {   
        return -1;
    }   
    strncpy(ifr.ifr_name, "eth0", IFNAMSIZ);
    ifr.ifr_name[IFNAMSIZ - 1] = 0;
    if (ioctl(sockfd, SIOCGIFADDR, &ifr) < 0)
    {   
        return -1;
    }   
    memcpy(&sin, &ifr.ifr_addr, sizeof(sin));
    ipaddr=inet_ntoa(sin.sin_addr);
#endif
    websSetIpAddr(ipaddr);
    websSetHost(ipaddr);
=============================================================================

! 修改源码后需重新编译,并下载到开发板

------------------------------------------------------------------------------------------

问题二(运行错误):
goahead: 0: Can't open config file route.txt
goahead: 0: Can't initialize server. Exiting.

解决办法:把 route.txt 拷贝到goahead可执行文件同一目录下。

------------------------------------------------------------------------------------------

问题三(运行错误):
goahead: 0: Can't open config file auth.txt
goahead: 0: Can't load auth.txt

解决办法:在goahead可执行文件同一目录下创建auth.txt。
# touch auth.txt

------------------------------------------------------------------------------------------

问题四:页面存放路径?

答:在goahead可执行文件目录下的web目录,自行创建web目录即可。
# mkdir web

------------------------------------------------------------------------------------------

问题五:CGI存放路径?

答:
1. 修改源码,使错误信息能正确显示(可选)
# vi src/cgi.c +93
error("Cannot find CGI program: ", cgiPath);
修改为:
error("Cannot find CGI program: %s", cgiPath);
! 修改源码后需重新编译,并下载到开发板

2. 创建cgi-bin目录
# mkdir web/cgi-bin

3. 修改配置文件
# vi route.txt
route uri=/cgi-bin dir=cgi-bin handler=cgi
修改为:
route uri=/cgi-bin dir=/opt/linux-arm-default/bin/web handler=cgi     // dir设置为web目录的绝对路径

4. 重启goahead
问题六:goahead:Unable to read key self.key Cannot initialize server. Exiting.
goahead: 0: Unable to read key self.key
goahead: 0: Cannot initialize server. Exiting.
安装 goahead 3.6.3 出现了以上问题 

解决办法:

  在goahead执行文件目录中找到self.key和self.crt文件拷贝到/etc/goahead下


- 测试

1. 创建 index.html (保存至web/index.html)
