Not sure why this is happening but you can fix it but adding any line after the saveas statement that would generate a value, e.g. just a "1" will do: #+begin_src org ,#+begin_src octave :results file :dir "data/images" :file "figure1.png" clf (); surf (peaks); saveas (1, "figure1.png"); 1 ,#+end_src #+end_src -- Eric S Fraga via Emacs 27.0.50, Org release_9.1.6-341-g3a4fd3 [-- Attachment #2: signature.asc --] [-- Type: application/pgp-signature, Size: 194 bytes --] ^ permalink raw reply [flat|nested] 3+ messages in thread

Based on the error hints, should be the calling to `ans` is wrong. After tesing upper code in Octave REPL, it works fine. that weird. The upper variable is just a wrapper around src block `body`for saving`ans` to file. Anyway, hope somebody who knows elisp and Octave can check this out.
