[Doxygen-users] 'Undefined control sequence' error when using user-defined Latex header.tex

[Alexey K. <ale...@gm...>]

Hi,

I'm using pdflatex to produce PDF file from Latex .tex files initially
generated by Doxygen from C-header files.

Problem description:

Doxygen is started with config file that contains LATEX_HEADER section with
absolute path to user-defined header.tex file. Doxygen generates
annotated.tex file which contains '\+' entries (probably some concatenation
commands).
Consequently pdflatex is executed and the error 'Undefined control
sequence' is reported, which points to undefined '\+' sequences inside
generated annotated.tex file.

If I execute doxygen at first without latex header input file, the default
generated header.tex contains the following line:

\newcommand{\+}{\discretionary{\mbox{\scriptsize$\hookleftarrow$}}{}{}}

By adding this line inside my user-defined header.tex file, the
aforementioned error disappears.

The question is how can I run doxygen to tell him to generate default latex
header in the first place and only after that to read my user-defined latex
header to overwrite specific commands inside my header file keeping all the
default generated commands as well?

Is it possible at all? Since I as user shouldn't be aware of every single
command internally used by Doxygen that I don't want to overwrite in
user-defined header input file.

Looking forward for your answer, thank you!
