I seem to be having some weird problems with the package siunitx. The package itself works but almost everything I try to add to it in the preamble doesn't work, e.g.:



\sisetup{load-configurations = abbreviations}


\DeclareSIUnit[per-mode=symbol,per-symbol=p]{\Bps {\byte\per\second}

all result in errors of the type:

The option `load-configurations' was not declared in package `siunitx', ...


Undefined control sequence

Does anyone have an idea what's happening here?

What version of siunitx do you have installed? Add \listfiles to your preamble and look at the log, or try texdoc siunitx from the command line and see what the PDF says. – Joseph Wright Jun 26 '12 at 17:25
in the \DeclareSIUnit... line you missed a } after \Bps. This could be the reason of the Undefined control sequence error. – Spike Jun 26 '12 at 20:24
Thanks Joseph, Running this made me realize that the version installed is V1.3a (that's the version that comes with TexLive in ubuntu's repos) while the doc I was looking for is V2.5e. I was thinking of installing the new version but than I saw that it depends on Latex3 which really doesn't seem like something I'd want to deal with now. I'll just use \newunit for mow :) Thanks again – Roey Angel Jun 26 '12 at 23:13
