Re: [Orgmode] Two questions about using a =#+begin_src emacs-lisp= block

[Chris Malone]

Ok, this is still perplexing me, as I have a new version from git and I still get the error.  The following is complete list (sorry for the long email!) of what I have done:

* Get a fresh copy of =org-mode= from git and byte-compile:

#+begin_src: sh
  cd ~/install/org-mode
  mkdir new_git_clone
  cd new_git_clone
  git clone git://orgmode.org/org-mode.git
  cd org-mode; make &> make.out
  ln -s ~/install/org-mode/new_git_clone/org-mode ~/install/org-mode/current
#+end_src

During the =make= process, I noticed quite a few warnings.  An example is below (for a complete copy of =make.out=, see http://astro.sunysb.edu/cmalone/nolink/make.out

* Attempt an export of the =org-mode= file found here: http://astro.sunysb.edu/cmalone/nolink/python_class_lstings.org

Exporting this to PDF, HTML, or ASCII (I didn't try other forms) results in the following error in the *Messages* buffer: 'Invalid read syntax: "#"'.  I turned on =debu-on-error= and the *Messages* and *Backtrace* buffers can be found here:

PS: I had already written most of this before I just saw your email - hopefully this helps...

Hi Eric,

I removed all the compiled elisp files, and the problem still persists.  Next step will be a completely fresh install from git; my current version is up to date, but maybe there was some conflict that git didn't complain about...

Hmm, it may be worth cleaning out all compiled .elc files from within
Org-mode, the calling org-reload, and see if the problem persists.
