When compiling a simple Netbeans C project that uses sockets I get the following output. I supose the problem is that gcc is not properly linking sockets.h library. Need a foolprof method to solve this. Thanks i advance
当编译使用sockets的一个简单的Netbeans C项目时，我得到了下面的输出。我认为问题是gcc没有正确地连接套接字。h图书馆。需要一个简单的方法来解决这个问题。由于我提前

You need the appropriate -l flag. I'm looking it up.
你需要合适的-l标志。我查找。
Duh. add -lsocket. Actually, you probably need -lnsl too. See this man page.
咄。添加-lsocket。实际上，你可能也需要-lnsl。看到这个男人页面。
In Netbeans this should be in the Project Properties.
在Netbeans中，这应该在项目属性中。

You need to make sure that the linker is linking the socket and nsl libraries. At the command line you would add -lsocket -lnsl to do so. I don't know netbeans and can't tell you how it works there exactly, but somewhere there should be linker settings where you can add these libraries.
您需要确保链接器正在链接套接字和nsl库。在命令行中，您将添加-lsocket -lnsl。我不知道netbeans，也不能确切地告诉您它是如何工作的，但是在某个地方应该有链接器设置，您可以在其中添加这些库。
