WG: AW: [Acdk-developer] Compiling problem

[Roger R. K. <ko...@ar...>]

Hi,

The problem with the code you send:
class ACDK_CORE_PUBLIC NewObjects : extends acdk::lang::Object=20

The macro ACDK_CORE_PUBLIC is reserved to acdk_core library to export =
the
symbols of acdk_core.
When you declare objects in executable, you don't need any export/import
macros:

class NewObjects : extends acdk::lang::Object=20

> This code can't be runned:
>      RStringBuffer sb1 =3D new StringBuffer("M");
>      RStringBuffer sb2 =3D sb1->clone();
This code should even not be compiled.
The clone() method returns a Robject and you should receive an error =
like
that:
 error C2440: 'initializing' : 'class RefHolder<class =
acdk::lang::Object>'
cannot be converted into 'class RefHolder<class =
acdk::lang::StringBuffer>'.

You have to cast the Robject result:
RStringBuffer sb2 =3D (RStringBuffer)sb1->clone();

> System::out->println(this->getClass()->getName());
> The result of this is "acdk::lang::Object".
ACDK uses metainfo / extented runtime type information generated by the
acdkmc compiler:

The first step is to modify the header:


ACDK_DECL_CLASS(NewObjects);

class NewObjects : extends acdk::lang::Object {
  ACDK_WITH_METAINFO(NewObjects) // THIS is for the metainfo
private:
	int myValue;
 =20
public:
	NewObjects(int intParam);
	virtual ~NewObjects();

	static int acdkmain(RStringArray args);

	void showValues();
};

acdkmc works for complete modules/directories. It also expects an header
file with the exact name of the directory. In this case acdktest1.h.

Then execute the metacompiler acdkmc:

C:\d\artefaktur\extern>ls
acdktest1  acdktest1.rar  acdkx_servlet

C:\d\artefaktur\extern>..\acdk\bin\acdkmc_d acdktest1
I: Analyse file: C:\d\artefaktur\extern\acdktest1\acdktest1.h
I: Analyse file: C:\d\artefaktur\extern\acdktest1\NewObjects.h

C:\d\artefaktur\extern>

This will generate 2 cpp files. Add the files to the project.
Then you will receive the results you expected.

   Dear Roger,

   Can you check the attached code with the project settings? I try your
suggestions but without success. Just 1st, the 2nd I can't understand.=20

   When I start the same application I found the following problems:
   1. System::out->println(this->getClass()->getName());
      The result of this is "acdk::lang::Object".
      I expect to be "NewObjects".
   2. This code can't be runned:
      RStringBuffer sb1 =3D new StringBuffer("M");
      RStringBuffer sb2 =3D sb1->clone();
  =20

   Best Regards,
   Miroslav Nachev
