Hi, I did what you said but still it is giving the same error,..[undefined reference] There is one line in the org file [[papers:paper2012][paper2012-paper]] [[bib:paper2012][paper2012-bib]] [[biblist:paper2012][paper2012-biblist]] This line is giving the error. If I remove this line from my org file, then everything is perfect. While I am trying to export pdf including that line, i am getting the error .[undefined reference]. Thanks a lot. ----------------------------- *Sanjib Sikder *Ph.D. Fellow Chemical Engineering IIT Bombay* * On Tue, Oct 2, 2012 at 7:55 PM, Bastien wrote: > Hi Sanjib, > > Sanjib Sikder writes: > > > or only > > > > (search "rtcite:" desc))) > > > > > > > > with this > > > > (or search "rtcite:" desc))) > > only this line. > > You get this error because Emacs tries to evaluate > > (search "rtcite:" desc) > > ... and it cannot, because search is not a function. > Search here is a variable (a string), hence > (or search "rtcite:" desc))) should return something > sensible. > > HTH, > > -- > Bastien >
