Pass Parameter

[amitk3553]

Hello,

 

In comments there are questions, answer please...Actually I have to pass parameter from the top.
 

#define test testcase_001     //have to pass parameter, is this right way? 

#include "testcases/test.cpp"   //could I pass parameterized value here?

class hci_test
{
   public:
   unsigned char* host_hci_pkt_arr;
   unsigned int address;
   test test_case;                       //could I make object handle like this(using parameter here)??
   hci_test()                                //constructor
  {
     host_hci_pkt_arr = new(nothrow) unsigned char [20];
     host_hci_pkt_arr[0] = test_case.host_hci_pkt_arr[0];     
     host_hci_pkt_arr[1] = test_case.host_hci_pkt_arr[1];
  }
};     

 

After compilation 

compiler throwing errors

:2nd line: error: testcases/test.cpp: No such file or directory

:9th line: error: ISO C++ forbids declaration of ‘testcase_001’ with no type

:9th line: error: ISO C++ forbids declaration of ‘test_case’ with no type

 

and when I comment first line of code and in 2nd and 9th line, instead of test, I write testcase_001, then it works fine means problem is in passing value from the top.

 

So let me know the corrections required in it if any or some other way to achieve this kind of passing parameters or values from the top, as #define is just used for aliasing or can do the work like parameter? Please respond

 

Thanks

I too want to know 

[amitk3553]

I think its not possible to pass some parameter from here, it seems compiler is not picking value of test in 2nd line? 

 

Need to add following line in makefile to implement the desired functionality?

 

#include "testcases/test.cpp"

Hello Sir,

Please get hold of a good C++ reference and read through it.

You are writing code for HCL, and asking on the forum whether

a declaration in your C++ code  is valid ?

  test test_case;                       //could I make object handle like this(using parameter here)??

Are you sure that class 'test' has a no arguments constructor ?

Where are you creating an object of type 'test' ?

Please try to correct the following:

testcases/test.cpp: No such file or directory

I am afraid no one else can help debug your code, without any

access to all your classes.

hello dakupoto,

 

this piece of code i had used as tescase in verification environment(SystemC and TLM) for testing  of systemC design of an IP.

 

in C++, these syntax are present, but I just want to know could i use them as I was saying. I just have to pass parameter from the top. 

 

If i put testcase_001(file name) in place of test, it works fine

testcases/test.cpp: No such file or directory

 

but I want to pass different test cases by just passing testcase's name in place of name in #define test  name

thats why I was asking can i do  all these things to achieve desired scenario.

 

and what does mean by HCL? 

 

Thanks

Hello Sir.

Let us clear the confusion here. May I suggest the following -- very widely used in both C++/

SystemC.

1. Put all test case classes in a ".h" file. When you want to use say "testcase_001" in a "*.cpp"

file, just use include the appropriate header file (that is the *.h file with the test case classes)

Will always work.

2. Make sure that each test case class has a no arguments constructor.

3. When you want to create an instance of a test case class, just do so by invoking the no

arguments constructor.

4. If you use the 'new' operator to create an array, please use a "delete [] <arrayname>;" in

the class destructor. You will save yourself lots of trouble and misery by staying away from

the new and delete.

5. Please use a destructor in each class

Hope that helps.

Thanks dakupoto,

 

I don't understood the meaning of following two lines, it means i cannot use hci_test() as i used in above code?Please throw some light on it.

 

2. Make sure that each test case class has a no arguments constructor.

3. When you want to create an instance of a test case class, just do so by invoking the no

arguments constructor.

If you're happy to use a Gnu extension with gcc, you can use a "computed include", e.g.

#define fred "testcases/testcase_001.cpp"
#include fred

However then you'd have to also write

#define test testcase_001

to make the code compile when it declares the class.

 

Perhaps you can do something like

#define test testcase_001
#define testinc "testcases/#test"
#include testinc

(again gnu only)
