Syntax highlighting within #+begin_src block in emacs orgmode not working

Question

I have tried many different languages and copied various examples, but none of my code blocks within orgmode get syntax highlighting. Here is what I\'m trying:

Answer 1

I had a similar problem where despite adding htmlize.el, I couldn't get the code syntax highlighting when exporting to html. I then found this very useful post and just followed the steps:

Syntax highlighting R code in WordPress using Emacs

Just to reiterate the steps:

1. I copied the htmlize.el in ~/.emacs.d/ directory
2. In org mode, typed M-x byte-compile-file and navigate to the directory where the htmlize.el is located, select it and press enter. This will compile the htmlize.el file.
3. Restart emacs and export a file with code block in it. The exported html file will now have syntax highlighted code.

Answer 2

Do you have this?
