@Janusz - I have tried it by making the `_init` folder and `config` file and put the following things. but its not even working.

 Package: Payroll
Version: 2.4
Name: Payroll And HRM 
Description: Payroll system for generating paychecks
 and tax forms, and administrating employees.
Author: Varadha 
Maintenance: Varadha 
Homepage: kvcodes.com
Type: extension
InstallPath: modules/Payroll

it creates an entry here in `installed_extensions.php` It will be like this. Version is not getting here.

  array (
    'package' => 'Payroll',
    'name' => 'Payroll',
    'version' => '-',     // if i change here 2.4, it works fine. 
    'available' => '',
    'type' => 'extension',
    'path' => 'modules/Payroll',
    'active' => false,
  ),

EDIT:

It doesn't check _init/config folder i think. Do something to fix it.

Every time i have to change it manually to take effect of it.

Thank you
Janusz and Apmuthu. I thought to change it in my _init/config file.

@itronics: Actually I was puzzled by how a length of a string returned by strspn() could be used though the logic was clear. Thanks for the fix.

There was a bug in above procedure, just fixed in FA repo here.
To install your module you have to set Version variable in your _init/config file to be compatible with current FA version, i.e. the version string have to begin with '2.4'

Thank you for pointing out the problem.

You must make the version of your package 2.4.something....

includes/packages.inc has at it's last function check_src_ext_version($ext_v) which has lines 725-741:

/*
    Check basic extension source compatibility.
*/
function check_src_ext_version($ext_v)
{
    global $src_version;

    $compat_levels = 2;    // current policy is keeping compatibility on major version level.
    $app = explode('.', strspn($src_version, "0123456789."));
    $pkg = explode('.', strspn($ext_v, "0123456789."));

    for ($i=0; $i < min($compat_levels, count($app)); $i++)
        if ($pkg[$i] < $app[$i])
            return false;

    return true;
}

This function returns true only if the package version (at major level 2) is greater than or equal to that of the FA version.

The $SysPrefs->version (or if absent, the $src_version) in version.php is used as the FA version.

The admin/inst_module.php at line 215 checks the above before the said warning / error arises:

            if (check_value('Active'.$i) && !check_src_ext_version($ext['version']))

This must be borne in mind when developing / updating modules in FA v2.4.

In FA v2.3, only a check for previous version < current version of the module was done.

I have recently developed a new module and tried to install it on 2.4 RC1. It's not working here. but its working fine with earlier version of Frontaccounting.

here is the warning message, when i try to actvate it.

 Package 'Payroll' is incompatible with current application version and cannot be activated. Check Install/Activate page for newer package version.

Help me to fix it.
