Hello, I have the following files I want to export to html: common.org: --8<---------------cut here---------------start------------->8--- #+TITLE: Unison Binaries #+OPTIONS: toc:nil num:nil #+HTML_HEAD: * sidebar :PROPERTIES: :CUSTOM_ID: sidebar :HTML_CONTAINER_CLASS: container-sidebar :END: - [[file:index.org::#OSX][Mac OS X]] --8<---------------cut here---------------end--------------->8--- index.org (extract) --8<---------------cut here---------------start------------->8--- #+INCLUDE: "common.org" * body :PROPERTIES: :CUSTOM_ID: mainbody :HTML_CONTAINER_CLASS: container-mainbody :END: ** Unison Binaries *** Mac OS X :PROPERTIES: :CUSTOM_ID: OSX :END: --8<---------------cut here---------------end--------------->8--- When I try to export index.org to index.html, I get: Reference "#OSX" in file "index.org" cannot be resolved without publishing What does it mean? And why can't the reference be resolved? Should I not use CUSTOM_ID for relative links?
