So you have your .bib files somewhere not next to your .tex file? This was the case for me. > Maybe one should set this variable to t per default. I don't think this is a good idea: ,----[ C-h v reftex-use-external-file-finders RET ] | reftex-use-external-file-finders is a variable defined in ‘reftex-vars.el’. | | Its value is nil | | Non-nil means, use external programs to find files. | Normally, RefTeX searches the paths given in the environment variables | TEXINPUTS and BIBINPUTS to find TeX files and BibTeX database files. | With this option turned on, it calls an external program specified in the | option ‘reftex-external-file-finders’ instead. As a side effect, | the variables ‘reftex-texpath-environment-variables’ and | ‘reftex-bibpath-environment-variables’ will be ignored. | `---- Changing the default of `reftex-use-external-file-finders' will break for people who have set `reftex-texpath-environment-variables' and/or `reftex-bibpath-environment-variables'.
