When I compile my document using latexmk.pl I get warning for every citation:
Latexmk: Citation 'XXX' on page YY undefinedThe citation appears in the References at the end of the document, but at the place of \cite only the (?) is shown.
The document is divided into many files in different directories, but
same happens in master tex file, the bib file is in root folder along
with master tex file.
Answers:
\cite{p413-viswanathan,p134-atkinson, p499-shlesinger} 中，各个bib-key的空格去掉就可以了
