Hi,

I am experimenting with the gorc resource compile, which suposedly can create coff object files for win64 from .rc files. See http://www.jorgon.freeserve.co.uk/Resource.htm#int fifth paragraph.

I created lazarus.obj with the following command line: C:\lazarus\source\lazarus\ide>c:\lazarus\downloads\Gorcjorg\GoRC.exe /machine X64 /fo lazarus.obj lazarus.rc

GoRC.Exe Version 0.90.2 - Copyright Jeremy Gordon 1998/2006 - Output file: lazarus.obj format: X64

Then I added this line to my program:
{$LINK lazarus.obj}
I got this error message
C:\lazarus\source\lazarus\ide\lazarus.pp(119,1) Error: Error reading COFF Symtable while reading lazarus.obj
Thne I tried something else and add the line
{$R lazarus.obj}
I starts to look for lazarus.or and I renamed the file. Then I got this error message
C:\lazarus\source\lazarus\ide\lazarus.pp(119,1) Error: Error reading COFF Symtable while reading ..\units\x86_64-win64\lazarus.or

I attached object file that gorc created.

And now the questions:
Am I taking the right steps to includes a resource file that won't be compiled by windres?

Is using gorc a possible way to create resource files for inclusion in win64 programs compiled with fpc?

Why does fpc complain about the COFF Symtable?

Vincent

Isn't this because we don't support the Microsoft .obj format? (the same reason why we can't link other .obj files)

I thought COFF is the name of the obj format supported by fpc.

From the gorc help page:

"It can make an OBJ file in COFF format, which is suitable for linking with other OBJ files to produce the final EXE or DLL."

Does Microsoft have a different COFF format?

From: "Jonas Maebe"

MS COFF .obj files are supported for win32 and wince. But it was not tested for win64...

Vincent, please create bug report so it will be fixed in future.

Yury.

Thanks, Yuri, for the clarification. I will create a bug report.

That's a common source of confusion. There are several different object formats which all call themselves COFF. COFF is a generic name.

At least 32 and 64 bit ;)
