Aloha Sanjib Sikder, It looks like BibTeX hasn't processed your document.
See the variable org-latex-to-pdf-process. By default I believe it just calls pdflatex several times. You can either insert a call to bibtex, or use a script, like this: (setq org-latex-to-pdf-process '("texi2dvi --pdf --clean --verbose --batch %f")) hth, Tom Sanjib Sikder <sanjibju2...@gmail.com> writes: > Hi, > > I tried the whole day trying the instructions through out various web pages > to have references in scientific document without any success. > > C-c C-e p produces the pdf file with question mark in place of reference. > > I have attached four files. > > BibAbb1.bib is my bibliography file > DOTemacs is the .emacs file > TestSciDocu.org is the org file for scientific writing > TestSciDocu.pdf is the output > > > Please help me in geeting the citation correctly :( > > I am using emacs-snapshot on Ubuntu 12.04. > > Thanks > > > > ----------------------------- > *Sanjib Sikder > *Ph.D. Fellow > Chemical Engineering > IIT Bombay* > > * > Hi,I tried the whole day trying the instructions through out various web > pages to have references in scientific document without any success.C-c C-e p > produces the pdf file with question mark in place of reference. > > > I have attached four files.BibAbb1.bib is my bibliography fileDOTemacs is the > .emacs fileTestSciDocu.org is the org file for scientific > writingTestSciDocu.pdf is the outputPlease help me in geeting the citation > correctly :( > > > I am using emacs-snapshot on Ubuntu > 12.04.Thanks-----------------------------<span > style="color:rgb(102,102,102)">Sanjib Sikder</span><span > style="color:rgb(153,153,153)">Ph.D. Fellow > > > Chemical EngineeringIIT Bombay</span> > > > > > -- Thomas S.
