Gsoap编译

Question

我正在尝试编写一个简单的 hello world gsoap 示例。我也包含了 http_get 插件。当我使用 :

编译时

g++ RestService.cpp soapC.cpp soapRestServiceSoap12Service.cpp -o server.exe -lgsoap++

我收到以下错误：

    soapRestServiceSoap12Service.cpp:(.text+0x0): multiple definition of `soap_encode_string'

下面是我的代码

#define soapRestServiceSoap12Service_H
#include "soapH.h"
#include "httpget.h"
#include "httpget.c"

Answer 1

我假设 RestService.cpp 和 soapRestServiceSoap12Service.cpp 在它们的 header 中都有 #include soapRestServiceSoap12Service.h 所以你在 httpget.c 中有一些函数的双重定义.您可以检查 here 是否有类似问题。

最好不要在 header 文件中包含 .cpp 或 .c 文件。我想你可以尝试删除 soapRestServiceSoap12Service.cpp 中的 #include "httpget.c" 然后在你的编译中，只需添加 httpget.c 源文件。

例如

g++ httpget.c RestService.cpp soapC.cpp soapRestServiceSoap12Service.cpp -o server.exe -lgsoap++

Gsoap编译

Gsoap compilation

c

c++

gsoap
