Hi Champ,
I am asking for my customer.
Since the DCL file is cut into the project, it is getting some problems with DCL header file.
As below attached pic, there are two header files in the project folder.
One is DCLCLA.h, another is DCLF32.h. As you could see, both files include DCL.h .
Since DCLCLA can pass the compile, but DCLF32 is fail. Is there any missing steps or problem with it ?

Thanks for any help.
Best regard, Johnny
