Question

我用gsoap ++库写了一个soap-client。一旦我把这个作为一个独立的测试应用程序编译它编译得很好，但当我尝试编译这些类包括在我的项目中我得到了很多链接错误：

等等。在Codeblocks中它链接罚款...这是我的Makefile：

我链接了所有必要的库（-lgsoapssl++ -lssl -lcrypto），我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

并且在图书馆中。那么，有什么问题？

Answer 1

可能的原因是为链接器指定了库的顺序，某些链接器要求包含函数定义的libarary出现在需要它的对象或库之后。尝试重新安排库定义，以便在此处进行测试，并检查您的链接器文档，看它是否需要它。

Answer 2

我相信你必须在你的make中编译一个gSoap的stdsoap2。*文件。生成的soapC文件取决于核心gSoap代码。

Answer 3

'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）

gsoap ++链接错误
