移植goahead到ucLinux注意事项
- fork()改为vfork(）
gethostbyname()改为intaddr.s_addr = inet_addr("192.168.1.100"); // 板子IP- https://www.linuxidc.com/Linux/2011-01/31076.htm

我的亲身经历
- ucLinux下新增uclibc库，编译并安装uclibc的方法参考《building uClibc.pdf》
- 我用的goahead-5.1.0，里面没有fork()，全是vfork（）。
- 注释掉IPv6
- 在src/goahead.h里定义
ME_COMPILER_HAS_SIGNLE_STACK - 注释掉
src/http.c/websOpen()里的setFileLimits()调用。
PUBLIC int websOpen(cchar *documents, cchar *routeFile)
{
WebsMime *mt;
webs = NULL;
websMax = 0;
error( "---> websOpen()\n");
websOsOpen();
websRuntimeOpen();
websTimeOpen();
websFsOpen();
logOpen();
// setFileLimits();
socketOpen();
if (setLocalHost() < 0) {
return -1;
}
- 修改
src/socket.c/socketOpen()里的AF_INET6为AF_INET，设置hasIPv6 = 0
- PUBLIC int socketOpen(void)
{
Socket fd;
if (++socketOpenCount > 1) {
return 0;
}
//#if ME_WIN_LIKE
//{
// WSADATA wsaData;
// if (WSAStartup(MAKEWORD(1,1), &wsaData) != 0) {
// return -1;
// }
// if (wsaData.wVersion != MAKEWORD(1,1)) {
// WSACleanup();
// return -1;
// }
//}
//#endif
socketList = NULL;
socketMax = 0;
socketHighestFd = -1;
error("---> socketOpen\n");
if ((fd = socket(AF_INET, SOCK_STREAM, 0)) != -1) {
closesocket(fd);
} else {
trace(1, "This system does not have IPv6 support");
}
hasIPv6 = 0;
return 0;
}
- 新增源文件的方法
在src目录下创建usercode目录，把新文件放在src/usercode/xxxx.c目录下。然后修改projects/goahead-linux-static.mk将新文件编译进去。
例如我新增一个hello.chello.h，在goahead.c中调用。
[root@localhost usercode]# pwd
/goahead-5.1.0/src/usercode
[root@localhost usercode]# ls
hello.c hello.h
《hello.c》
#include
void showhello(void)
{
error("hello jimbo");
}
《hello.h》
#include "goahead.h"
void showhello(void);
《goahead.c》
/********************************* Includes ***********************************/
#include "goahead.h"
#include "hello.h" //包含头文件
省略。。。
MAIN(goahead, int argc, char **argv, char **envp)
{
char *argp, *home, *documents, *endpoints, *endpoint, *route, *auth, *tok, *lspec;
int argind;
showhello(); //调用
#if WINDOWS
if (windowsInit() < 0) {
return 0;
}
#endif
