Re: Option clash for package xcolor

Ho un file .sty con questo codice:

Alla compilazione però ricevo l’avviso:

`! LaTeX Error: Option clash for package xcolor.

See the LaTeX manual or LaTeX Companion for explanation.
Type H for immediate help.
…

l.22 \usepackage
{multirow}
? H
The package xcolor has already been loaded with options:
[dvipsnames]
There has now been an attempt to load it with options
[table,dvipsnames]
`

e la compilazione si blocca. Come faccio a identificare il pacchetto
che carica xcolor? O l’errore può essere dovuto ad altra causa?

Te lo dice il messaggio: uno dei pacchetti precedenti. Siccome ci sono solo quelli di classicthesis che possono dare il problema, la soluzione è caricare xcolor subito dopo textcomp
