Error while generating the documentation

[Nikola]

After running ./playground docu I get the following error:

Generating C++ examples for /home/nirangor/project/myOpenWNS/tests/system/wifimac-tests
Generating Python examples for /home/nirangor/project/myOpenWNS/tests/system/wifimac-tests

Traceback (most recent call last):
  File "./toolchain/sphinx-build", line 5, in <module>
    from pkg_resources import load_entry_point
ImportError: No module named pkg_resources
make: *** [html] Error 1

So problem gets solved after installing these packages:

python-pkg-resources
texlive-latex-base
texlive-latex-extra
texlive-latex-recommended
texlive-fonts-recommended

Best regards,
Nikola

Dear Nikola,

Thanks a lot for your patience and testing.

To permanently fix this and provide users with a better feedback it would be beneficial to check these prerequisites before executing the playground.py docu command. I don't think we should add these packages to the official dependency list, because most of the people will only download the latest official documentation from the website and will not build it on their own.

Does anybody have an idea how to implement a check in the docu command to test if the prerequisites above are met?

Best Regards,
  Daniel
