eclipse c＆＃x2b;＆＃x2b;，通过CMD作品编译，在Eclipse中不可行
我使用Winsock库有一个TCP客户端程序（TCPCLIENT.CPP）。如果我将命令行与以下呼叫一起使用：
g++ TCPClient.cpp -o TCPClient.exe -lws2_32
当我尝试使用mingw中的eclipse/c ++链接相同的脚本时，成功生成了 *.exe，则我似乎会生成 *.o文件，但生成时会遇到错误*.exe。 因此，如果ecplise/c ++执行以下（链接器调用），则会生成错误：
g++ -o TCPClient.exe TCPClient.o -lws2_32
我得到多个错误：

c：\ mingw \ bin \ ld.exe：矮人错误 如果使用CMD线并首先生成.o文件，然后尝试生成一个 *.exe，则会遇到相同的错误。 CMD行中的以下两个调用导致上面的错误：
g++ TCPClient.o -o TCPClient.exe -lws2_32
g++ TCPClient.o -o TCPClient.exe
这意味着：如果在CMD行中，我只指定我要生成（A *.exe从我的 *.cpp中），一切正常。但是 - 作为用户 - 单独执行这两个步骤不起作用。
CMD线G ++调用似乎“知道”在这里该怎么做。作为用户，直接生成 *.exe时，我从未看到 *.o文件。但是我认为必须生成吗？我错了吗？为什么没有进一步规格的CMD线知道如何处理.o文件？ ...是否可以从任何来源中找出对“ G ++”的调用，当通过命令行调用时会有什么？当然，我希望将相同的设置集成到Eclipse/C ++中。
I have a TCP Client program (TCPClient.cpp) using winsock library. An *.exe is generated successfully if I use command line with the following call:
g++ TCPClient.cpp -o TCPClient.exe -lws2_32
When I try to compile and link the same script within Eclipse/C++ using MinGW I seem to get the *.o file generated but I get an error when generating the *.exe.
Thus, the error is generated if Ecplise/C++ does the following (linker call):
g++ -o TCPClient.exe TCPClient.o -lws2_32
I get multiple errors:

The following is interesting:
I get the same errors if I use the cmd-line and first generate a .o file and then try to generate a *.exe. Both of the following calls in cmd-line result in the error from above:
g++ TCPClient.o -o TCPClient.exe -lws2_32
g++ TCPClient.o -o TCPClient.exe
This means: If in cmd-line I only specify that I want to generate (a *.exe from my *.cpp) everything works fine. But - as a user - doing those two steps separately does not work.
Cmd-Line g++ call seems to "know" what to do here. As a user I never see the *.o file when directly generating a *.exe. But I think it must be generated anyway? Am I wrong? Why does cmd-line without further specification know how to deal with the .o file? ... Is it possible to find out from any source what a call to "g++" does when called via command line? Of course I want the same settings integrated in eclipse/c++.

如果您执行-O（大写字母，而不是零），则可以获得该错误，而不是-o对于EXE文件。
You can get that error if you do -O (capital letter, not zero) instead of -o for the exe file.
