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

Dear Bastien,

thanks for the response. I did some debugging, but I am not an expert of
elisp and org-mode. Anyway, this is what I found:

I put a breakpoint in fuinction org-latex-src-block() which receives
src-block as parameter. This parameter contains field language already set
to c++\"-std=c++11\", which is of course wrong. Therefore the problem is
before this function is called, but I could not follow the chain and so I
do not know precisely which function is responsible for this.

Also, the bug triggers also when I specify C as a language. Therefore,
probably the problem is somewhere in ob-C.el.

Thanks again

Giuseppe Lipari

I think the following patch fixes the issue. I'll let Eric decide if it
has to be applied or not.

Thank you for the report.

Ah well. This is getting embarrassing. Third, and hopefully last,

Dear Nicolas,

I applied  your patch to the latest version (from git) and now it works!
