Remember to cover the basics, that is, what you expected to happen and
what in fact did happen.  You don't know how to make a good report?  See

     http://orgmode.org/manual/Feedback.html#Feedback

Your bug report will be posted to the Org-mode mailing list.
------------------------------------------------------------------------

Dear all,

I have a problem with org-babel and the export of C++11 code to LaTeX.

I report below a simple example of a problem file:

---------------------

#+TITLE: CPP example
#+LaTeX_HEADER: \usepackage{minted}
#+LaTeX_HEADER: \usemintedstyle{emacs}


* Example of c++11

An example of c++11

#+HEADERS: :results output :exports both
#+name: Example
#+BEGIN_SRC cpp
#include <vector>
#include <iostream>

using namespace std;
int main()
{
    std::vector<int> v = {1, 2, 3};

    for (auto x : v) cout << x << ", ";
    cout << endl;
}
#+END_SRC

And these are the results:

#+RESULTS: Example
: 1, 2, 3,

------------------

If I export this file to LaTeX everything works fine, and I see the code
nicely formatter in the pdf file. Unfortunately, when I try to compile and
execute the
code with C-c-C-c, I get an error: in facts, to compile the code above
according to
the c++11 standard, I need to specify ":flags -std=c++11". Therefore, I
changed the header as follows:

------------------

#+BEGIN_SRC cpp :flags -std=c++11
...
#+END_SRC

---------------------

Now, when I press C-c-C-c, I the code is compiled and executed
correctly. However, I get another problem: when exporting to LaTeX,
the code disappears from the pdf file. By looking at the generated .tex
file, I see the following lines:

---------------------
\begin{minted}[]{cpp"-std=c++11"}
...
\end{minted}
---------------------

As you can see, the flags are wrongly copied after the language
specification. Therefore, minted does not work and does not output the
code.

I tried to put the :flags specification in the HEADERS, but it does not
work (fails for compile).

Also, the results do not appear in the pdf file, even by specifying
":exports both".

Any clue of what it is going on?

Best

Giuseppe Lipari
