sphinx.ext.pngmath raise an error when I try a simple expression

Question

I'm using Sphinx to create the documentation of my project. I want to use the extension sphinx.ext.pngmath and with this little test:

    Returns the indefinite integral of the polynomial *poly*:
    .. math::
        \int p(x)dx

I got the error:

WARNING: inline latex u'\\int p(x)dx\n\n': latex exited with error:

I have installed the package texlive-latex-base.

Thank you, rubik

Answer 1

texlive-full will install all the texlive packages which is indeed a bit of an overkill.

You can install just texlive-latex-extra to fix this particular problem.
