问题描述

我正在尝试从头文件生成 gsoap 类

soapcpp2.exe test.h

在哪里 test.h

// test.h

#define MY_STRUCT_NAME_LEN 50

typedef struct MY_STRUCT_TYPE
{
    char name[MY_STRUCT_NAME_LEN];
}MY_STRUCT;

int op1(MY_STRUCT* a, int b, int * r );

我的问题是#define MY_STRUCT_NAME_LEN 50al line:3 未被识别。

test.h(7): *WARNING*: undefined identifier 'MY_STRUCT_NAME_LEN'


test.h(7): *WARNING*: char[30681240620171331] will be serialized as an array of 30681240620171331 bytes: use soapcpp2 option -b to enable char[] string serialization or use char* for strings


    test.h(7): **ERROR**: undetermined array size

    Saving soapStub.h annotated copy of the source interface header file
    Saving soapH.h serialization functions to #include in projects

    test.h(12): *WARNING*: serializable typedef 'MY_STRUCT' is not namespace qualified: schema definition for 'MY_STRUCT' in WSDL file output may be invalid

    Saving soap.nsmap namespace mapping table

    Saving soapServer.cpp server request dispatcher
    Saving soapServerLib.cpp server request dispatcher with serializers (use only for libs)
    Saving soapC.cpp serialization functions

    There were errors:
    1 semantic error
    3 warnings

如果我将 line:7 更改为

char name[50];

它会正常工作。

我真的更喜欢使用宏来确定字符串的大小(实际情况更复杂)。有人可以帮忙吗?

解决方案


由于这个问题被标记为 C++ 并且您使用的是 soap cpp 2:您可能不应该使用定义typedef struct ...和字符串的字符数组。这就是说,如果没有特别的理由限制字符串长度,请将您的代码重写为:

class test {
    public:
    std::string name;
};

int op1(test* a, int b, int * r );

结果编译成功,没有任何警告。
