各位高手:        我手邊有些fortran撰寫的subroutine，     想轉成dll檔，讓BCB可以使用，我已爬過站上的文章，   ( RaynorPao版大: (VC-BCB 整合系列一) 如何由 BCB 使用 VC 所產生的 LIB 及 DLL  )     也試成功用VC寫的dll檔在BCB呼叫，但是fortran轉出的dll檔就是不能用？     請各位高手不吝指教,謝謝         我先用Power Station 4.0開了寫dll的project，內容為:        subroutine for_sub(a)    implicit none    integer :: a    a=a*a    return    end subroutine for_sub      成功complie成FOR_DLL.dll檔後，在BCB以動態連結的方式呼叫:      #include  #pragma hdrstop #include "Unit1.h" #include "File1.h" //--------------------------------------------------------------------------- #pragma package(smart_init) #pragma resource "*.dfm" TForm1 *Form1; typedef void (*FOR_SUB)(int*); //--------------------------------------------------------------------------- __fastcall TForm1::TForm1(TComponent* Owner) : TForm(Owner) { } //--------------------------------------------------------------------------- //--------------------------------------------------------------------------- void __fastcall TForm1::Button1Click(TObject *Sender) { int a=3; HINSTANCE dll=NULL; FOR_SUB for_sub=NULL; dll=LoadLibrary("FOR_DLL.dll"); if(dll!=NULL) { for_sub=(FOR_SUB)GetProcAddress(dll, "for_sub"); if(for_sub!=NULL) { for_sub(&a); ShowMessage(IntToStr(a)); } FreeLibrary(dll); } } //---------------------------------------------------------------------------
