Direct Draw from JEDI does not work under 64bit

Hi,
I have DirectDraw Headers from JEDI.
They work with 32bit compilation, but not with 64bit(It compiles but if run: CreateSurface fails).
I have setup a test:

Please Help

If I use original Delphi Headers it works on Delphi 32&64bit.
But on FPC only 32bit, not 64bit(Same Problem as by JEDI Headers)

Quick test shows that your SizeOf( TDDSURFACEDESC ) is wrong. It should be 120 bytes on Win64 that is based on the one in unit p_ddraw (included with FPC).
I noticed your have:
Code: Pascal
[Select]
[+]
[-]
{$MINENUMSIZE 4}
{$ALIGN ON}
in your DDraw unit.
Replacing it with:
Code: Pascal
[Select]
[+]
[-]
{$PACKRECORDS c}
AND removing "packed" from two records:
Code: Pascal
[Select]
[+]
[-]
...
{$PACKRECORDS c}
{engkin}
{ $MINENUMSIZE 4}
{engkin}
{ $ALIGN ON}
...
_DDCOLORKEY
=
{engkin}
{packed}
record
...
_DDSURFACEDESC
=
{engkin}
{packed}
record
...
fixes the problem.
Prabably you need to remove it from all the records.
Edit:
Attached DDraw unit.

Thx to engkin
The JEDI ddraw works now for fpc 32 & 64 bit.
But under Delphi only 32bit.
Do I need other changes to make it works for Delphi 64?

I don't have Delphi, so I can only suggest to use the usual $ifdef way.

Perhaps you can Check the second Test, IT works for Delphi 32&64 but only for fpc33

Perhaps ist easyer to go from the Delphi Implementation to fpc.
Check the second Test.

I think this should work. Give it a try. It is based on the Delphi project you shared above.
I noticed the project itself has issues, but not related to this.

Compared to the previous test, it did not close as the relevant message was commented out, and the caption of the form was random characters.
