我用 gsoap++ 库写了一个肥皂客户端。一旦我将这个编译为独立的测试应用程序，它就编译得很好，但是当我尝试编译这些类（包括在我的项目中）时，我得到了很多链接错误：

等等。在代码块中，它链接罚款......这是我的Makefile：

    $(CC) $(LDFLAGS) $(OBJECTS) -o $@
clean:

.cpp.o:

我链接了所有必要的库 ( -lgsoapssl++ -lssl -lcrypto) 并检查了这些库中的请求函数：

$ nm /usr/lib/libgsoapssl++.a | grep soap_begin_count
00018da0 T soap_begin_count

图书馆里有。那么，有什么问题？

造成这种情况的一个可能原因是为链接器指定库的顺序，一些链接器要求包含函数定义的库出现在需要它的对象或库之后。尝试重新安排库定义，以便在这里出现这种情况，并检查您的链接器文档以查看它是否需要这样做。

我相信您必须在您的 make 中编译 gSoap 的 stdsoap2.* 文件之一。生成的soapC 文件依赖于核心gSoap 代码。

'stdsoap2.cpp' 需要来自 gsoap 源目录。

PATH_TO_GSOAP_BUILD/gsoap-2.8/gsoap/stdsoap2.cpp（假设gsoap-2.8）
