gsoap++ 链接错误

Question

我用 gsoap++ 库编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：

../common/UserGausClient/UserGausClient.o: In function `GAUS::SSLInit()':

等等。在 Codeblocks 中，它的链接被罚款......这是我的 Makefile：

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，有什么问题吗？

Answer 1

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。

Answer 2

一个可能的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，以便在此处出现这种情况，并检查您的链接器文档以查看它是否需要。

Answer 3

'stdsoap2.cpp' 需要来自 gsoap 源目录。

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