Fatal error: Call to a member function link() - opencart

i am receiving an error while editing extensions in opencart.
Fatal error: Call to a member function link() on a non-object in C:\xampp\htdocs\organics2you\admin\controller\module\couponpop.php on line 28


this problem because the different version just creat variable and pass object of url as $data['url']=$this->url; and call it from your temp;

Plugin makes options dropdown not working in opencart product

I have a problem with Option tab on Add/Edit product. The problem is that when I installed the extension Autocomplete No More and when I choose Option it throws this error
Fatal error: Uncaught Error: Call to a member function getOptionData() on null in /../ocartdata/storage/modification/admin/controller/catalog/option.php:437
in option.php line 437 is
$option_data = $this->model_extension_catalog_autocomplete_no_more->getOptionData($this->request->post['option_id']);
And full function is this one
public function getOptionData() {
if (isset($this->request->post['option_id'])) {
$this->load->language('catalog/option');
$this->load->model('catalog/autocomplete_no_more');
$this->load->model('tool/image');
$option_data = $this->model_extension_catalog_autocomplete_no_more->getOptionData($this->request->post['option_id']);
$this->response->setOutput(json_encode($option_data));
}
}
Is anyone has an idea why this throws null?

Issue:
You are trying to call a method of an Object
$this->model_extension_catalog_autocomplete_no_more
with the extension in the object name.
but then you are loading the model without the extension in the path:
$this->load->model('catalog/autocomplete_no_more')
So obviously the Error signals that you have not yet defined this object
Call to a member function getOptionData() on null
Solution:
Fix it by adding extension to the path:
$this->load->model('extension/catalog/autocomplete_no_more')
or remove if from the object name:
$this->model_catalog_autocomplete_no_more

error: ‘struct arphdr’ has no member named ‘ar_sha’

I'm creating my own ARP eader with below shown code, however this code ain't working, I get error message as ‘struct arphdr’ has no member named ‘ar_sha’, ar_spa, ar_tha, ar_tpa. I've checked net/if_arp.h, these members are part of struct arphdr. Why i'm unable to use them?? Please assist.
arp.ar_hrd=htons(ARPHRD_ETHER);
arp.ar_pro=htons(ETHERTYPE_IP);
arp.ar_hln=6;
arp.ar_pln=4;
arp.ar_op=htons(ARPOP_REQUEST);

Encoutering an error 'run executed for function module' while calling function

I wrote one module in proc iml and trying to call it using call fuctiong and supplied parameters.
But its throwing the erorr:
run executed for function module.
Any suggestion?

The error message says that you have defined a function that returns a value ('function module') so you need to call it like this:
x = MyFunction(x,y,z);
You cannot use the CALL statement to call a function, only to call subroutines that do not return values.

C++ Does Not Name A Type

I get confused when I get errors like these
I have
FxSmartPtr<FxStreamable> able(FcNew,stream->StreamInObject());
FxGlobalPair pair(id,able);
I get an error on FxGlobalPair pair(id,able); that is able is not a type.
I tried modifying to
FxGlobalPair pair(id,FxSmartPtr<FxStreamable>::able);
but I get an error that is error: 'class FxSmartPtr<FxStreamable>::able' has not been declared
What concept am I missing?
UPDATE: typedef pair<FxID, FxSmartPtr<FxStreamable> > FxGlobalPair;
UPDATE 2:
Heading

I think that you have found the Most Vexing parse
The problem is that
FxSmartPtr able(FcNew,stream->StreamInObject());
may define a function named able, instead of a variable.

function call missing argument list error

am trying to convert a bullet quaternion(btQuaternion) to an irrlicht quaternion(irr::core::quaternion) for a game am prototyping.
btQuaternion orientation= rigidBody->getOrientation();//now turn bullet quaternion -> irrlicht
finalOrientation= core::quaternion(orientation.getX, orientation.getY, orientation.getZ, orientation.getW);
However am getting an error i cant figure out.
Error 1 error C3867: 'btQuadWord::getX': function call missing argument list; use '&btQuadWord::getX' to create a pointer to member c:\users\matia\documents\visual studio 2008\projects\bulletimplant\bulletimplant\bulletimplant.cpp 86
Error 2 error C3867: 'btQuadWord::getY': function call missing argument list; use '&btQuadWord::getY' to create a pointer to member c:\users\matia\documents\visual studio 2008\projects\bulletimplant\bulletimplant\bulletimplant.cpp 86
Error 3 error C3867: 'btQuadWord::getZ': function call missing argument list; use '&btQuadWord::getZ' to create a pointer to member c:\users\matia\documents\visual studio 2008\projects\bulletimplant\bulletimplant\bulletimplant.cpp 86

visual studio is complaining about a function call missing an argument list but i cant find a solution. Please help. Thanks

Assuming none of the functions expect any argument, I believe you need :
finalOrientation= core::quaternion(orientation.getX(), orientation.getY(), orientation.getZ(), orientation.getW());
The compiler complains because getX, getY, getZ and getW are functions, and functions should be followed by an argument list when invoked.
