Hi Chuck,
even with a minimal init file.
If you ever set the value of `org-export-babel-evaluate' to nil this
might produce the behavior you describe.
Maybe, but as stated in the manual: "Setting the
org-export-babel-evaluate variable to nil will ensure that no code
blocks are evaluated as part of the export process."
From here: http://orgmode.org/manual/Exporting-code-blocks.html
The thing is that I indeed want to make sure that the code blocks are
evaluated, but to me evaluation of code block is different than what to
export from the Org file. It is often the case that I don't want export
to evaluate anything, but just to export what is in the Org file's
markup (while following what the header parameters say).
Thanks,
Fred
