Dear everyone,

It is my first posting in cfd-online forum. Thanks for all kind reply in advance.

I want to generate Doxygen document of OpenFOAM. First, I generated latex file using Doxygen. Then I use command make pdf to get pdf output from the latex output. But this step didn't success. The error info :

pdfTeX warning: pdflatex (file ./a01981_a63dde5ed963ede3c2c7a3681dd742999_icgra
ph.pdf): PDF inclusion: multiple pdfs with page group included in a single page.

And I don't know what does it mean. Anyone can help me?

Greetings Felix_Lee,

I have to say that last time I tried to generate a LaTeX based PDF file from the OpenFOAM code documentation was a long time ago. And the conclusion at the time was that it was a very lousy format for OpenFOAM's code documentation, simply because the formatting scheme used is not applicable to paper format. It is designed for web-browsing only.

The error seems to indicate that there is an issue with overlapping pages or that a graph is too large to fit in a single page.

If you Google the error message:

PDF inclusion: multiple pdfs with page group included in a single page.

you'll find several answers on this topic.
Looks like it is as what the message states at the beginning, namely:

pdfTeX warning

as in: it's just a warning. There was a new feature introduced into the PDF format by Adobe and the warning is possibly a bug. A fix seems to be to use pdf2ps and ps2pdf to convert the PDF file to PS and then back to PDF again.

Best regards,
Bruno

Dear Bruno,

You said the formatting scheme is designed for web browsing only.I think you are right. And I will use the html files only. It's enough for using.
Thank you for your answer.

Best regards,
Felix
