What does C-h v org-export-use-babel RET say?

If the result is not `t' that is the problem, and somewhere in your setup 
you have set that variable (or its predecessor org-export-babel-evaluate) 
to nil or something other than `t'.

If this is the problem, set org-export-use-babel to `t'. You might 
also note the advice in the docstring:

"Users who wish to avoid evaluating code on export should use the header
argument ‘:eval never-export’."

HTH,

Chuck

That was indeed the culprit. I had switched it off to speed up export. After
setting that to t again it works (of course). Drawbacks are, that I need to
confirm the evaluation in each export (I am a bit hesitant to generally
accepting src block evaluation), and evaluation takes time.

I do not really need src block evaluation during export. I only need to
evaluate (manually) when I changed the graphics src, what I am doing
anyway to check the changed image.

But how would I control the (not-)inclusion of the src code during
export in that case?

Thanks,

Martin

I am using the following:

(add-to-list 'org-babel-default-header-args '(:eval . "never-export"))
(add-to-list 'org-babel-default-inline-header-args '(:eval . 
"never-export"))

As I wrote:

#+begin_quote

You might also note the advice in the docstring:

"Users who wish to avoid evaluating code on export should use the header
argument ‘:eval never-export’."

#+end_quote


If that was not clear, review

(info "(org) Exporting code blocks")

particularly the paragraph that starts "Turning off evaluation..."
