我迷失在指针的黑社会中!这是我的问题,
非常古怪,我只能控制其中一个功能,所以请不要说我需要重新设计。 这是使用android-ndkr7在Linux Ubuntu 11.04中编译的。它是一个纯粹的本机应用程序(或服务),将在Android手机上运行。我正在使用谷歌测试来验证我的类/功能。 第一个函数(我的测试类)必须声明unsigned char *,它将它传递给第二个函数用作输出(crypt :: encryptBuffer),encrypt接受声明的变量,为它分配内存并将其传递给第三个函数,它是将值作为输出放入其中的位置。
Crypt.h
class Crypt
{
public:
Crypt();
~Crypt();
bool encryptBuffer(const unsigned char* inDecryptBuffer, const int inputSize, unsigned char** outEncryptBuffer, int* pOutSize);
};
#endif
Crypt.cpp
#include "Crypt.h"
#include "pan/crypt.h"
static unsigned char HydraEncryptionKey[] = {0x17, 0x43, 0x9B, 0x55, 0x07, 0xAE, 0x73, 0xB1, 0x32, 0x10, 0xE0, 0x22, 0xD9, 0xC7, 0xF2, 0x3B};
bool AccCrypt::encryptBuffer(const unsigned char* inDecryptBuffer, const int inputSize, unsigned char** outEncryptBuffer, int* pOutSize)
{
int encryptedSize;
pan::aes128_cbc enc(HydraEncryptionKey);
// see how long the encrypted data will be and allocate space for the data
encryptedSize = enc.output_len( inputSize );
*outEncryptBuffer = (unsigned char*)malloc(encryptedSize + 4);
enc.encrypt(inDecryptBuffer, *outEncryptBuffer, inputSize );
return true;
}
CryptTest.cpp
#incude "Crypt.h"
#include <gtest/gtest.h>
#define CHECK_COND(X, a, b, c) { \
if(X) \
{ \
printf("FAIL: %s\n", c); \
printf("Press any key to continue");\
getc(stdin);\
}\
else \
{ \
printf("PASS: %s\n", c); \
}\
}
#define EXPECT_EQ(a,b,c) CHECK_COND((a != b), a, b, c)
const char* decBuff = "something";
const int inputSize = 10;
unsigned char* encBuffTest = NULL;
int pOutsize = 0;
class cryptTester : public testing::Test
{
protected:
virtual void SetUp()
{
cryptTest = new Crypt();
cryptTest->encryptBuffer((const unsigned char*)decBuff, inputSize, &encBuffTest, &pOutsize);
}
virtual void TearDown()
{
}
Crypt* cryptTest;
};
TEST_F(AccCryptTest, decryptBuffer)
{
int poutSize = 0;
EXPECT_EQ(true, accCryptTest->decryptBuffer((const unsigned char*)encBuffTest, pOutsize, &outDecryptBuffTest, &poutSize), "decryptBuffer(valid, valid)");
}
这将编译正常,但是当我在手机上运行时,我遇到了分段错误。我无法弄清楚这是怎么回事,因为我无法从adb shell正确设置调试。
任何帮助将不胜感激!

您的代码似乎没问题,可能错误在encrypt
方法中:
enc.encrypt(inDecryptBuffer, *outEncryptBuffer, inputSize );
