I want to create a document with the iodhbwm class. If I compile it the first time it works fine. But if I compile it a seccond time this lines apear at the begin of the document:

id=1,dest=636861707465722E31,srcline=235C3333346265727363687269667420617566204562656E6

The log file shows the following error:

I already contacted the author of the iodhbwm class. But he was not able to reproduce this error. Because of this he couldn't help me.

Now I think that it must be something else. I compile this code. It is an example from the documentation of iodhbwm.

documentclass[

    load-dhbw-templates,

    auto-intro-pages = default,

    add-tocs-to-toc,

    debug,

    language = ngerman

]{iodhbwm}

usepackage[T1]{fontenc}



dhbwsetup{%

    author                  = my name,

    thesis type             = SA,

    thesis title            = Verwendung von iodhbwm,

    student id              = 12345,

    institute               = Masterfind Factory faltfe,

    course/id               = Txxxx,

    supervisor              = Pikachu und Enton,

    processing period       = {01.01.17 -- 31.01.17},

    location                = Dreamtown

}



begin{document}

    Blinddocument

end{document}

I am using MikTex 2.9.6941 on Windows 7 and I reinstalled MikTex two times.

Realy interessting is, that this lines disappear if I include hyperref. But normaly the class is doing this by it self.

Do somebody know why there are this lines?
Is somebody else able to reproduce this errors?

The problem is that the KOMA-classes now load bookmark if hyperref is detected. It is doing it in a AfterAtEndOfPackage command. The iodhbwm class loads hyperref in AtEndPreamble, so bookmark is loaded then too and this is too late for it: bookmark can't write to the aux-file the needed line

providecommandBKM@entry[2]{}

An simple document to reproduce the problem:

documentclass{scrreprt}

usepackage{etoolbox}

AtEndPreamble{

 usepackage{hyperref}

 }



begin{document}

chapter{abc}

end{document}

Probably the only work-around is to prevent that bookmark is loaded:

documentclass[bookmarkpackage=false]{scrreprt}

usepackage{etoolbox}

AtEndPreamble{

 usepackage{hyperref}

 }



begin{document}

chapter{abc}

end{document}

Edit

A simple work-around is to load auxhook earlier:

documentclass{scrreprt}

usepackage{etoolbox,auxhook}

AtEndPreamble{

 usepackage{hyperref}

 }



begin{document}

chapter{abc}

end{document}

Thanks to answer from Ulrike the problem is a change within KOMAScript.

At the moment there is no support to pass a key value option which does not belong to the iodhbwm class itself.

There are to possibilities to fix this issue for now. The first one is loading bookmark in the preamble itself.

documentclass[...]{iodhbwm}

usepackage{bookmark}

The second option is to use an internal command which is used to pass options to the base class.

makeatletter

    newcommand{iodhbwm@cls@baseclass@options}{bookmarkpackage=false}

makeatother

A complete example would look like

makeatletter

    newcommand{iodhbwm@cls@baseclass@options}{bookmarkpackage=false}

makeatother

documentclass[

    load-dhbw-templates,

    auto-intro-pages = default,

    add-tocs-to-toc,

    debug,

    language = ngerman

]{iodhbwm}

usepackage[T1]{fontenc}



dhbwsetup{%

    author                  = my name,

    thesis type             = SA,

    thesis title            = Verwendung von iodhbwm,

    student id              = 12345,

    institute               = Masterfind Factory faltfe,

    course/id               = Txxxx,

    supervisor              = Pikachu und Enton,

    processing period       = {01.01.17 -- 31.01.17},

    location                = Dreamtown

}



begin{document}

    Blinddocument

end{document}

But please don't abuse the internal command.

The main problem is not KOMA-Script. bookmark uses package auxhook to write the definition of a command into the aux-file. AddLineBeginMainAux of auxhook has two different modes of working:

• If @beginmainauxhook is relax, it writes immediately to the aux-file.


• If @beginmainauxhook is not relax, AddLineBeginMainAux adds its argument to @beginmainauxhook.

If the package is loaded via AtBeginDocument it initializes @beginmainauxhook with relax. If not, it initializes it to make itself relax and tries to patch document to add the execution of @beginmainauxhook just after the opening of the main aux file.

Now, if you load hyperref via AtEndPreamble, hyperref loads auxhook and auxhook cannot recognize, that patching of document is to late. Because of this @beginmainauxhook is never executed.

So the bug is, to load hyperref via AtEndPreamble without loading auxhook before begin{document} and without explicite executing @beginmainauxhook. If you have a look into the aux-file you will find in this case also, that the line

providecommandhyper@newdestlabel[2]{}

that hyperref usually writes into the aux-file (immediately after the initial relax) is missing. This is because of not executing @beginmainauxhook.

So I would say, this is a bug in iodhbwm and it should be changed to load auxhook earlier. As a workaround you can load auxhook in the document preamble. Both would also bring back the line

providecommandhyper@newdestlabel[2]{}

into the aux-file.
