Hello:

I would like to write mex[1] files in pascal, so I would like to adapt the DelphiMex[2] library from delphi to pascal. But I don't know Delphi, so I would thanks if somebody can help me. At this moment I have the following dude, in the cited library the autor wrote the following procedure:

692 procedure DelphiMexInitIO;
693   begin
694     with TTextRec(Output) do
695      begin
696        Mode := fmoutput;
.             BufSize   := sizeof(Buffer)-1;  { Leave a space to pad with #0 }
.             BufPtr    := @Buffer;
.            OpenFunc  := @MATLABOC;
             InOutFunc := @MATLABOUT;
             FlushFunc := @MATLABOUT;
             CloseFunc := @MATLABOC;
             Name[0]   := #0;
         end;
      end;

The variable "Output" has not been previously declared, so when I try to compile fpc outputs the following message

pascalmex.pas(694,12) Error: Illegal type conversion
pascalmex.pas(696,10) Error: Identifier not found MODE
I wonder if in delphi lines 692-694 equivalent to the following lines???:
692 procedure DelphiMexInitIO(Var Output:TTextRec);
693   begin
694     with Output do

Or perhaps in delphi Output is a wellknow variable?

Cheers

[1] mex files are used in Matlab to implement external functions, using non-matlab languages as C or Fortran.

[2] DelphiMex is a Library that wrote Alexandre Kampouris in order to write mex files in delphi. (See http://radio-bip.qc.ca/DelphiMEX/DelphiMEX.html )

Which compiler and os do you use? Did you try
with systuils.TTextRec(Output) do
in line 694?

Which compiler and os do you use?
fpc 1.0.6 in linux.

Did you try with systuils.TTextRec(Output) do in line 694?

I had not. But it works.

Now I manage to crash matlab with a segmentation fault. I am continuing my investigation.

Thanks
