Re: mkoctfile problem

hello

I have command mkoctfile –v TWUsetUserAgent.cc

I try to compile this code

 

 

// TWUsetUserAgent.cc

#include <octave/oct.h>                                   

#include "TWUsetUserAgent.h"

 

DEFUN_DLD(TWUsetUserAgent, args, , "")

{

  octave_value retval;

 

  if (args.length() == 1)

  {

    std::string ua = args(0).string_value();

    if (! error_state)

    {

      retval = std::string(TWUsetUserAgent(ua.c_str()));

 

 

    }

   

  }

  else

    print_usage();

 

  return retval;

}

 

 

 

 

// TWUsetUserAgent.h

 

#ifndef TWUSETUSERAGENT_H

#define TWUSETUSERAGENT_H

 

#ifdef  __cplusplus

extern "C"

{

#endif

 

    typedef   char const *    TWUsetUserAgent_t(char const * );               

    TWUsetUserAgent_t TWUsetUserAgent;

   

#ifdef  __cplusplus

}

#endif

 

#endif

 

and

 

// TWUsetUser.c

#include "TWUsetUserAgent.h"

 char const * TWUsetUserAgent(char const * new_user_agent)

{

    char const* user_agent_name;

    if( new_user_agent && *new_user_agent  && ( 81 > strlen(new_user_agent)))

    {

        user_agent_name = new_user_agent;

    }

    return user_agent_name;

}

 

I have compiled program with msvc und build TWUClib.lib and TWUClib.dll

 

 

 

If I use

 

mkoctfile TWUsetUserAgent.cc, then it’s with following error

 

> mkoctfile TWUsetUserAgent.cc

TWUsetUserAgent.o:TWUsetUserAgent.cc:(.text+0x4d6): undefined reference to `_TWUsetUserAgent'

collect2: ld returned 1 exit status

octave-3.0.2.exe:66:C:\Programme\Octave

 

Ok link error my header file can not find TWUsetUser.c

 

 

If I try the code like following to write

 

// TWUsetUserAgent.h

#ifndef TWUSETUSERAGENT_H

#define TWUSETUSERAGENT_H

 

#ifdef  __cplusplus

extern "C"

{

#endif

 

    typedef   char const *    TWUsetUserAgent_t(char const * );               

    TWUsetUserAgent_t TWUsetUserAgent;

   

#ifdef  __cplusplus

}

#endif

 

#endif

 

char const * TWUsetUserAgent(char const * new_user_agent)

{

    char const* user_agent_name;

    if( new_user_agent && *new_user_agent  && ( 81 > strlen(new_user_agent)))

    {

        user_agent_name = new_user_agent;

    }

    return user_agent_name;

}

Then it’s is ok but it is not normal I need to call a lot of source.

 

I have to call either my TWUClib.lib or direct connect to TWUsetUser.c

 

 

Thanks

Hello

How did you use mkoctfile command?

From octave prompt?

Did you try 

   `-v'
   `--verbose'
         Echo commands as they are executed.
like 
octave:>mkoctfile -v foo.cc

?

Anyway your information is not enough to answer.

Regards

Tasuro
