Question

我需要将这个c ++类转换为python模块并给出错误 / * arexcrypt.h * /

#ifndef AREXCRYPT_H
#define AREXCRYPT_H

//Qt
#include <QString>
#include <QVector>
#include <QFlags>
//App
#include "singleton.h"

class ArexCrypt: public Singleton<ArexCrypt>
{
friend class Singleton<ArexCrypt>;

public:
enum Compression {
    IfReducedCompress,
    AlwaysCompress,
    NeverCompress
};
enum IntegrityCheck {
    NoCheck,
    ChecksumCheck,
    HashCheck
};
enum Error {
    NoneError,
    NoKeyError,
    NoDataError,
    UnknownVersionError,
    IntegrityError
};
enum CryptoFlag{
    NoneFlag = 0,
    CompressedFlag = 0x01,
    ChecksumFlag = 0x02,
    HashFlag = 0x04
};

Q_DECLARE_FLAGS(CryptoFlags, CryptoFlag);

void setKey(quint64 pKey);
Compression CompressionMode() const;
void setCompressionMode(Compression pMode);
IntegrityCheck IntegrityProtectionMode() const;
void setIntegrityProtectionMode(IntegrityCheck pMode);
Error LastError() const;

//METHODS
QString EncryptToString(const QString &pText);
QString DecryptToString(const QString &pEncryptedText);
QString GenerateIntegrityKey(const QString &pText);
bool CheckIntegrityKey(const QString &pText);

private:
//Data
quint64 key;
QVector<char> keyParts;
Compression compressionMode;
IntegrityCheck protectionMode;
Error lastError;
bool showConsoleMessages;

//CONTRUCTORS AND DESTROYERS
ArexCrypt();

//METHODS
void SplitKey();
void EncryptArray(QByteArray &pArray);
void DecryptArray(QByteArray &pArray);
QByteArray GenerateIntegrityData(QByteArray dataArray, CryptoFlags &flags);
QByteArray EncryptToByteArray(QByteArray pTextArray);
QByteArray DecryptToByteArray(QByteArray pEncryptedArray);
//OTHERS
QString EncryptToString(QByteArray pTextArray);
QString DecryptToString(QByteArray pEncryptedArray);
QByteArray EncryptToByteArray(const QString &pText);
QByteArray DecryptToByteArray(const QString &pEncryptedText);
};

Q_DECLARE_OPERATORS_FOR_FLAGS(ArexCrypt::CryptoFlags);

#endif // AREXCRYPT_H

/ arexcrypt.i /

/* arexcrypt.i */
%module arexcrypt
%{
#include "arexcrypt.h"
%}

%import "singleton.i"
%include std_string.i
%include std_vector.i
%include stl.i
%include "arexcrypt.h"

/ * singleton.h * /

#ifndef SINGLETON_H
#define SINGLETON_H

template <typename T> struct Singleton
{
    static T &instance()
    {
        static T m_instance;
        return m_instance;
    }
protected:
    Singleton() { }
};

#endif // SINGLETON_H

/ * singleton.i * /

/* singleton.i */
%module singleton
%{
#include "singleton.h"
%}

%include "singleton.h"
%template(intSingleton) Singleton<int>;

然后当我转换为python时，我在控制台上得到了这个

swig -c ++ -python arexcrypt.i

arexcrypt.h（11）：警告401：关于基类＆＃39; Singleton＆lt; ArexCrypt＆gt;＆＃39;。忽略。 arexcrypt.h（11）：警告401：也许你忘了实例化＆＃39; Singleton＆lt; ArexCrypt＆gt;＆＃39;使用％模板。 arexcrypt.h（40）：警告504：函数ArexCrypt :: Q_DECLARE_FLAGS（CryptoFlags，ArexCrypt :: CryptoFlag）必须具有返回类型。忽略。 arexcrypt.h（81）：警告503：不能包装ArexCrypt :: CryptoFlags＆＃39;除非重命名为有效的标识符。

gcc -c arexcrypt_wrap.cxx -o arexcrypt.o -fpic -std = c ++ 0x

我明白了

任何人都知道可能会发生什么，我做错了

Answer 1

作为一项规则：始终查看第一个错误 - 这可能是您的罪魁祸首。

在你的情况下

arexcrypt_wrap.cxx:1: warning: -fpic ignored for target (all code is position independent)
arexcrypt_wrap.cxx:171:21: error: Python.h: No such file or directory

你错过了python开发文件。

带有swig到python模块的c ++类
