I'm using this CV template and it was working fine in the past. But now the same file gives the following error:

package keyval error: bibtex8 undefined

I tried the following two different codes:

    , bibstyle=authoryear-comp
    , labelyear=false
    , defernumbers=true
    , maxnames=20
    , firstinits=true
    , uniquename=init
    , dashed=false


, bibstyle=authoryear-comp
, labelyear=false
, defernumbers=true
, maxnames=20
, firstinits=true
, uniquename=init
, dashed=false
, backend = bibtex8

Any help in this regard will be highly appreciated.

Have you tried with bibtex as the option for backend, and then run bibtex8 instead of bibtex? – Guido Mar 17 '13 at 9:23
I get no errors. Please add a minimal working example (MWE) that illustrates your problem. Is your distribution up to date? – Marco Daniel Mar 17 '13 at 9:28
Thanks @Guido for your comment. Can you explain your comment in detail? Thanks – MYaseen208 Mar 17 '13 at 9:36
According to the biblatex manual biblatex does not know whether one runs bibtex or bibtex8. The differences between bibtex8 and bibtex (beside memory) are on sorting (mix-case sorting is allowed in bibtex8) and handling of non-ASCII characters. The other option is to check whether you distribution is up to date (and eventually you can have a go with biber). – Guido Mar 17 '13 at 10:48
@MYaseen208 Can you add \listfiles to your input and see what the resulting File List in the log says? I wonder what version of biblatex you have installed. – Joseph Wright Mar 17 '13 at 11:22

The problem is that you are giving


instead of the required


as bibtex8 is a value for the backend key and not a key in its own right.

A full example which works fine for me:

Even using \usepackage[backend=bibtex8]{biblatex} throws the same error. – MYaseen208 Mar 17 '13 at 12:07
I'm using this cv template. – MYaseen208 Mar 17 '13 at 12:13
@MYaseen208 Please try my MWE and compare your file list to mine, then report back. – Joseph Wright Mar 17 '13 at 12:14
Every item my file list exactly matches with yours. Thanks a lot for your time and effort. – MYaseen208 Mar 17 '13 at 12:22
@MYaseen208 In that case something odd is going on: can you e-mail me your .log file (joseph.wright@morningstar2.co.uk) – Joseph Wright Mar 17 '13 at 12:23
