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.
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 = new StringBuffer("M");
RStringBuffer sb2 = sb1->clone();
Best Regards,
Miroslav Nachev

RRK> 1.
RRK> You have to enable RTTI in your compiler settings, otherwise nothing will
RRK> work - even if you eventually able to link the executable.
RRK> This aplies to all compiler on all platforms.
RRK> 2.
RRK> On Windows you have to export classes/methods from you DLL you want to use
RRK> them outside the DLL.
RRK> Create a header in your library:
RRK> #ifndef mylib_Config_h
RRK> #define mylib_Config_h
RRK> #include <acdk.h>
RRK> #if defined(IN_MYLIB_LIB)
RRK> # define ACDK_MYLIB_PUBLIC ACDK_DLL_EXPORT
RRK> #else
RRK> # define ACDK_MYLIB_PUBLIC ACDK_DLL_IMPORT
RRK> #endif
RRK> #endif //mylib_Config_h
RRK> Now for the class inside your mylib:
RRK> class ACDK_MYLIB_PUBLIC MyClass
RRK> : extends acdk::lang::Object
RRK> {
RRK> // ...
RRK> };
RRK> In the compiler settings for the mylib.dll project you have to define
RRK> IN_MYLIB_LIB.
RRK> In the compiler settings for the executable, which make use of mylib.dll,
RRK> you don't need to define this symbol.
RRK> Hope this helps,
