# 1.4. Solaris/SunOS 程序员要注意的事情

当编译 Solaris 或 SunOS 平台的代码时，你需要指定一些额外的命令行参数，以链接（link）正确的库（library）。为了达到这个目的，可以在编译命令後面简单加上＂-lnsl -lsocket -lresolv＂，类似这样：

```shell
$ cc -o server server.c -lnsl -lsocket -lresolv
```

如果还是有错误信息，你可以再加上一个＂-lnext＂到命令行的後端。我不太清楚这样做了什麽事，不过有些人是会这样用。

你可能会遇到的另一个问题是调用 setsockopt()。这个原型与在我 Linux 系统上的不一样，所以可以这样替换：

```c
int yes=1;
```

输入这行：

```c
char yes='1';
```

因为我没有 Sun 系统，所以我无法测试上面的资料，这只是有人用 email 跟我说的。
