編譯錯誤：「創建負數大小的數組（'-0x00000000000000001'）」，「分配只讀位置」

您好我是GoogleMock的新手，但並不是新的嘲笑（我有Python經驗）。編譯錯誤：「創建負數大小的數組（'-0x00000000000000001'）」，「分配只讀位置」

對於基於C代碼的界面，我們希望使用Googlemock。編譯一切順利。沒有問題與限定基於C的代碼：模擬頭文件

#include "gmock/gmock.h" 
extern "C" 
{ 
    #include "interface/interfacetype.h" 
} 
struct HELPER 
{ 
    virtual ~HELPER() {} 
    virtual int interface_func(ID_ENUM_TYPE id, MY_STRUCT_TYPE *params) = 0; 
}; 
struct INTERFACE_MOCK : public HELPER 
{ 
    MOCK_METHOD2(interface_func, int(ID_ENUM_TYPE id, MY_STRUCT_TYPE *params)); 
}; 
extern INTERFACE_MOCK *mock_create_mock(); 
extern void mock_delete_mock();

模擬實現：

#include mock.h 
extern "C" 
{ 
    #include "interface/interfacetype.h" 
} 
INTERFACE_MOCK *interface_2_mock = NULL; 
extern "C" 
{ 
    int interface_func(ID_ENUM_TYPE id, MY_STRUCT_TYPE *params) 
    { 
     return interface_2_mock->interface_func(id, params); 
    } 
} 
INTERFACE_MOCK *mock_create_mock() 
{ 
    if (interface_2_mock == NULL) 
    { 
     interface_2_mock = new(INTERFACE_MOCK); 
    } 
    return interface_2_mock; 
} 
void mock_delete_mock() 
{ 
    delete interface_2_mock; 
}

MY_STRUCT_TYPE如下：

typedef struct my_struct_tag 
{ 
    float value[196] 
} MY_STRUCT_TYPE

單元測試碼是如下：

INTERFACE_MOCK *interface_2_mock; 

class fixture : public ::testing::Test 
{ 
    protected: 
     virtual void SetUp() 
     { 
     interface_2_mock = mock_create_mock(); 
     } 

     virtual void TearDown() 
     { 
     mock_delete_mock(); 
     } 
}; 


TEST_F(fixture, test_case) 
{ 
MY_STRUCT_TYPE params; 
int result = 0; 
for (int i=0; i<196; i++) 
{ 
    params.value[i] = 1.23; 
} 
// I'm only interested in checking that function is called, 
      // mocking the return-value and mocking 'params' which is an output-param 
EXPECT_CALL(*interface_2_mock, interface_func(_, _)) 
      .Times(2) 
      .WillRepeatedly(DoAll(SetArgReferee<1>(&params), return 0))); 
// Call function_under_test which calls interface_func 
result = function_under_test(); 
      ASSERT_EQ(0, result) << "Return-value " << result << " not as expected" 
}

編譯這一切都很順利，直到編譯EXPECT_CALL行。在那裏，我們有以下錯誤，我們不明白：

你能幫助我們嗎？

最有可能的「大小爲負創造陣」源於「窮人的靜態斷言」，即在某處程序員編寫了一個編譯時斷言的程序，以確保某些值是正確的，當它失敗時，會得到上述錯誤。 – Lundin 2014-10-29 14:49:26

@Lundin：感謝您的回覆，但事實證明，傳遞引用和傳遞指針引用不應該混淆。正如我在下面解釋的，我應該使用SetArgPointee i.s.o. SetArgReferee。 – Nemelis 2014-10-30 08:35:43

這次我找到了答案。取而代之的SetArgReferee < 1>（& PARAMS），我應該用SetArgPointee < 1>（PARAMS）
