Date Posted: 11 Feb 07 at 5:29PM

I have been using 5.11 without a problem. I just installed 5.21 and updated my search path. I tried both "ActiveX DCU" and "DLL DCU," but both require uiSEDQuickPDF.pas. I am using Delphi 7 and both of the zip files include "D7." Therefore, I assume that they have been compiled for D7. I installed 5.14 and that one works fine.

Hi!

Perhaps there're still other/older DCUs in your project-paths?
Is the uiSEDQuickPDF.dcu in your project-path the one from the D7-package? ...I think no ;-)

Best regards,
Ingo

I had already search my drive for copies of uiSEDQuickPDF.dcu. I have versions 5.11, 5.14, and 5.21 unzipped into separate directories. I re-ran the search and confirmed that those are the only three copies of the file on my drive. I can switch the "Library Path," under "Environment Options," between 5.11 and 5.14 without a problem. It is only 5.21 that causes a problem. To be sure, I deleted uiSEDQuickPDF.dcu for 5.11 and 5.14 and set the path to 5.21 and I still get the error that it requires: uiSEDQuickPDF.pas.

The file dates that I have are:

5.11 - 2005 April 1

5.14 - 2006 March 20

5.21 - 2006 December 30 (from QPDFv521-DLL-DCU-D7.zip)

Hi!

I've sent a mail to Michel in this case...
Perhaps he can help.
Try the dll first so you don't waste time.

Best regards,
Ingo

Hi Ulrich, and bb46970,

    I don't understand. My Delphi 7 DCU zip files dated 30 Dec 06 (both of them) do contain the uiSedQuickPDF.dcu file. To be sure, I downloaded the two zip files, and decompressed them, and both had the file.

    So, perhaps I am not understanding the problem. Is there something wrong that I did when I compiled the library and generated the DCU files? Sorry, I am not a Delphi person, so I need help to understand.

    Thanks!

Michel,

the problem ist not a real missing uiSEDQuickPDF.dcu file. It's the compiler claiming a somewhat strange error.
I haven't had the time to dig deeper but what I think it is a problem with the locally used unit ZLIBEX together with a probably already installed version.

@bb46970: what's your delphi environment: do you have ZLibEx installed separatly?

@all: could someone try to use the precompiled dcu's for D7 who has not installed ZLlibEx in any other directory?

Thanks,
Ulrich

Ulrich, maybe you are right. but before we continue I want to ask for another test.

bb46970, please use the command line compiler for delphi. It does not use your Delphi settings and the path to your libraries must be specified in command line. For compilation use:

setlocal

set somelib=C:\Delphi\Components\MyLib\

set dprfile=myproject.dpr

rem

rem To specify unit path use: -U"pathtodcu's"

rem To specify include path use: -I"pathtodcu's"

rem

rem For more than 1 library use -I<path>, -U<path> for

rem each referenced library.

rem

rem To specify exe output path use: -E"EXE"

rem To specify dcu output path use: -N"EXE"

rem

dcc32 -I"%somelib%" -U"%somelib%" %dprfile%

if errorlevel 1 (

rem compilation failed.

pause

)

endlocal

</cmd>

If it compiles with errors then I believe that Ulrich is right. It may not have to do with ZLIB library (ZLIB from QuickPDF was the last Wrapper found on zlib.org) but with another dependency (maybe standard classlibrary) which may change as result of a delphi service pack.

In this case the compiled reference to some delphi units is invalid and because program wants to recompile the whole project it fails with "file not found".

Ok, I have sent Michel a new compiled D7 version. Problem was a version conflict on ZLibEx and two missing res-files (at least then it works on my system)

@bb46970: can you test this version on your system? Drop me an email so I can send it to you: ulrich . kobsa at t-online [dot] de

HTH,
Ulrich

Ulrich,

after I have checked the source code I have found the following inside uPDFFontConst.pas:

...

implementation

{$R isqpglyphlist.res} // <-- reference to resource file
{$R isqpdingbats.res} // <-- reference to resource file

uses
Windows, SysUtils, uPDFFlate;
...

The problem is caused by uPDFFontConst.pas and not uiSEDQuickPDF.pas. The compiler just stopped on the first compiled unit which refers to uPDFFontConst.pas and it was uiSEDQuickPDF.pas in this case.

As much as I know the resource files are not embedded by the compiler inside dcu files and are processed separately by linker. This means that a proper compiled image must contain the dcu files and res (-ources) as well.

Maybe bb46970 may confirm if his old image contains a copy of these res files. If yes, please copy them inside 5.21 directory and give your program another try. If it works now we have fixed this problem.

Best regards, Marian

Ulrich,

ZLibEx.dcu is in the 5.21 directory, with uiSEDQuickPDF.dcu.

Ulrich,

I tried sending you an E-Mail. Let me know if you get it or not. I get so much SPAM that I have Europe blocked. I pinged your domain and made an exception for the IP address, but if it comes from a different IP address, it will not make it.

Ulrich,

I have been trying, unsuccessfully, to send you an E-Mail.

Thanks Ulrich. I have updated the D7 DLL DCUs with the corrected one that you sent, and I took down the ActiveX one until someone can send me a fixed version.

Cheers!

Hi Michel!

I've forgotten the res-files in my ZIPs, too...
Can you insert the both files and zip/upload again?

Best regards,
Ingo

Michel, if you add the res files to your archives it schould work with old dcu's as well.

http://www.quickpdf.org/forum/member_profile.asp?PF=312&FID=15 -

bb46970 can you please try to compile your 5.21 image (the one with problems) and add there the 2x res files from 5.14 version. Can you please confirm if it works.

Marian

Marian,

I copied the two .res files, but it still does not compile.

David,

there should be fresh compiled DCUs for D7 available on download section. Can you try them and report your results?

Thanks,
