I'm trying to use the Inline::CPP module with a custom library.

The library is something as follow:

class ae_util {
    public:
  ae_util();
  ~ae_util();

  static string str_time( char * str_fmt = "%Y%2m%2d_%2H%2M%2S" );
  .........
[download]

body ae_util.cpp

// ****************************
ae_util::ae_util()
 {
    }
    // ****************************
 ae_util::~ae_util()
{
    }
    /************************************************************
 ************************************************************/
    string ae_util::str_time( char * str_fmt )
    {
    string sres;
    char str_res[100];
    const time_t now = time(0);
    strftime( str_res, 100, str_fmt, localtime( &now ) );
    sres = string(str_res);
    return sres;
    }
[download]

 

I compiled the files inside a kdevelop project and the convert it as library from the obj file as:

$ gcc --shared -o ae_util.so  ../xxx/yyyy/ae_util.o
[download]

At last I tried to use it inside a perl program as follow

#!/usr/bin/perl

use Inline CPP => Config => LIBS => './ae_util.so';
use strict;

print " test1  ", ae_util::strtime( '%Y%2m%2d_%2H%2M%2S' );
[download]

I get the following error:

Undefined subroutine &ae_util::strtime called at ./inline2.pl line 11.

or

#!/usr/bin/perl<br>
# use Inline CPP => Config => MYEXTLIBS => './ae_util.so';
use Inline CPP => Config => LIBS => './ae_util.so';
use strict;

my $obj = new ae_util(1);
print " test1  ", $obj->strtime( '%Y%2m%2d_%2H%2M%2S' );
[download]

I get the following error:

Can't locate object method "new" via package "ae_util" (perhaps you fo
+rgot to load "ae_util"?) at ./inline2.pl line 7.
[download]

Where I'm wrong on that ?

there are somewhere some good tutorial about using external custom library with perl program ?

regards, Enzo
