That is not the case here, they have supplied two obj files, one is 32 and the other 64 bit. The problem seems to be that neither is a valid COFF file according to my Fpc (or Lazarus) in any case.

I think they provide something that will work with Delphi rather than for C. The reply from THALES is linking to no less than 7 different archive files for various use of the keys. In one of these I found an example for *Delphi 10*, which contained an updated interface file and a 32 bit object file: spromeps.pas superpro.obj (I do not think I even ever had Delphi 10...) I copied these to my project and disabled the old versions. Then I tried to cross-compile to Win32 on Lazarus 2.2.4 and Fpc 3.2.2. Syntax check (Run/Quick_Compile) finishes successfully. But the Compile does not, it fails like this: - Compile Project, Mode: Default, OS: win32, CPU: i386, Target: DongleTest.exe: Exit code 1, Errors: 1 DongleTest.lpr(28,1) Error: Illegal COFF Magic while reading D:\Engineering\Projects\Subversion\PC\DongleTest\superpro.obj - The same happens if I set the target to default everywhere so going for 64 bit. In tyhis case I had to switch to the spromeps.pas superpro.obj files from the same archive but for 64 bit applications. Here the error when I try to compile: -- Compile Project, Mode: Default, Target: DongleTest.exe: Exit code 1, Errors: 1 DongleTest.lpr(28,1) Error: Failed reading coff file, illegal reloctype $000A while reading D:\Engineering\Projects\Subversion\PC\AgiDongleTest\superpro.obj -- So again I have the problem with the obj file(s) which are now more recent than the old single one. How can I check the obj file for "type"? I have asked this before here but now cannot find if I got an answer or not... Is there some command I can use to check what kind of an obj file I have? Is it possible to find anything by looking at the interface file spromeps.pas, which is the interface from the main application towards the obj file? ThHis pretty much looks like the old file to me except it has more available API calls and also some defines for MSWINDOWS and LINUX respectively in the implementation part defining all the API calls into the driver. My problem is that I do not have any Delphi on my new (from 2019) laptop except Delphi-7... So I guess I have to check if my test app can be opened in Delphi7 using the supplied obj file and if it works there, how do I proceed?

Re: [fpc-pascal] Converting Delphi7 code to FreePascal with interfacing to protection key?
There will surely be better responses than mine, but imho there is an inconsistency in your code: Near/Far calls are a relict of the 16-bit DOS/Win3.x era. The {$F+} switch should be completely obsolete for both Win32 and Win64 executables. .obj files are compiled code (pieces) which are not yet linked together. I cannot imagine that there is a chance to convert a 32-bit .obj file into a .64-bit .obj file without recompilation (i.e. having the sources). So I'd assume that you are stuck to the 32-bit architecture or you might try to obtain a 64-bit .obj from the manufacturer. Maybe he's even released a complete library with a documented API in the meantime? (Even though the hardware key is old it could still be supported as part of the driver series of the manufacturer's current hardware.) - Original Message - From: Bo Berglund via fpc-pascal To: fpc-pascal@lists.freepascal.org Sent: Tuesday, March 21, 2023, 23:49:30 Subject: [fpc-pascal] Converting Delphi7 code to FreePascal with interfacing to protection key? We have a number of old Delphi7 applications which are in need of porting over to FreePascal. I have successfully done a number of these ports in the last few years... But now I am up against a bit of a problem regarding software we have protected using an USB connected hardware key originally bought from Rainbow, a company that has been bought up in several steps and is now named THALES. Anyway, our software interfaces to the SuperPro protection keys is via a Windows driver from THALES and they have provided a software integration kit way back when we started using the keys. It consist of a Delphi unit basically containing a list of definitions of available API functions into the driver looking like this: -- { Force FAR calls } {$F+} INTERFACE CONST { SuperPro API error codes } SP_SUCCESS = 0; SPRO_MAX_QUERY_SIZE= 56; TYPE RB_SPRO_APIPACKET = ARRAY [1..1028] OF CHAR; { Spro API Packet } RB_SPRO_APIPACKET_PTR = ^RB_SPRO_APIPACKET; FUNCTION SproInitialize( ApiPacket : RB_SPRO_APIPACKET_PTR ) : WORD; FUNCTION SproGetExtendedStatus( ApiPacket : RB_SPRO_APIPACKET_PTR ) : WORD; IMPLEMENTATION USES Windows; {$L SPROMEPS.OBJ} { LINK WITH THE SUPERPRO OBJECT FILE } { External functions } FUNCTION RNBOsproFormatPacket( ApiPacket : RB_SPRO_APIPACKET_PTR; thePacketSize : WORD ) : WORD; STDCALL; EXTERNAL; FUNCTION RNBOsproInitialize( ApiPacket : RB_SPRO_APIPACKET_PTR ) : WORD; STDCALL; EXTERNAL; FUNCTION SproInitialize( ApiPacket : RB_SPRO_APIPACKET_PTR ) : WORD; VAR returnVal : WORD; BEGIN returnVal := RNBOsproFormatPacket (ApiPacket, RB_SPRO_APIPACKET_SIZE); IF returnVal <> SP_SUCCESS THEN SproInitialize := returnVal ELSE SproInitialize := RNBOsproInitialize (ApiPacket); END; { SproInitialize } BEGIN END. -- Obviously being from the time when it was received the OBJ file SPROMEPS.OBJ to be linked in is a 32 bit type, so the ported programs need to be compiled/linked into a 32 bit exe file on Windows.

It is the interface to the protection key driver on the Windows system... It does work for our 32 bit Delphi7 programs on Windows 10 x64, so there must be some 32<->64 bit handling in Windows maybe? -- Bo Berglund Developer in Sweden ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org https://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org https://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal
Re: [fpc-pascal] Converting Delphi7 code to FreePascal with interfacing to protection key?

I have successfully done a number of these ports in the last few years... But now I am up against a bit of a problem regarding software we have protected using an USB connected hardware key originally bought from Rainbow, a company that has been bought up in several steps and is now named THALES. Anyway, our software interfaces to the SuperPro protection keys is via a Windows driver from THALES and they have provided a software integration kit way back when we started using the keys. It consist of a Delphi unit basically containing a list of definitions of available API functions into the driver looking like this: Obviously being from the time when it was received the OBJ file SPROMEPS.OBJ to be linked in is a 32 bit type, so the ported programs need to be compiled/linked into a 32 bit exe file on Windows. Questions: -- 1) How should I go about translating the above to current FreePascal syntax? This involves: { Force FAR calls } {$F+} You can normally skip this. {$L SPROMEPS.OBJ} { LINK WITH THE SUPERPRO OBJECT FILE } This can be problematical, since you need to know it is in the correct format for the linker. 2) Is there a way to translate/convert the 32 bit Windows SPROMEPS.OBJ file into a 64 bit one such that it could be used for a 64 bit fpc compiler? It is the interface to the protection key driver on the Windows system... I doubt this can be done. It does work for our 32 bit Delphi7 programs on Windows 10 x64, so there must be some 32<->64 bit handling in Windows maybe? I do not think there is special handling. 64 bit windows simply runs 32-bit windows programs. Basically, due to the .OBJ file, I think you're stuck with compiling 32-bit programs if you require that .obj file. Maybe the THALES company has a 64-bit version of the .OBJ file.
