LaTeX forum ⇒ General ⇒ looking for an old version of siunitx

[vladimir]

Hello,

I'm using kile on Centos 7 and i would like to use siunitx package, because it's useful.
My problem is that i didn't find texlive-siunitx nor texlive-science via yum.
All the available rpm, that i found was for other kind of distribution than the redhat family.
I went on CTAN.org, to download siunitx.dts.zip. I unzip it in /usr/share/texlive/texmf and lunch texhash command.
Kile find the package but i got an error Support~package~expl3~too~old when compiling with PDFLaTeX.
So via yum, i update texlive-l3kernel.noarch and texlive-l3package.noarch without result.
Via gedit in root mod, i open siunitx.sty and modify the date on line 20 \@ifpackagelater { expl3 } { 2015/09/11 } to bypass the problem. Obviously some other errors appears.

So here is my questions:
- Does anyone had an old version of siunitx.dts.zip to avoid the first error message?
- Does anyone know the meaning of line 4878 on siunitx.sty ?

Code: [Select all] [Expand/Collapse] [Download] (untitled.tex)

\bool_if:nF
   {
    \sys_if_engine_luatex_p: ||
    \sys_if_engine_xetex_p:
   }

luatex and xetex are well installed.

Sorry for my bad english

Installing packages manually is bound to give errors like the one you're experiencing. I'd rather not use TeX Live pre-packaged for your OS from some package depository as those are known to be outdated and only are updated very slowly. It is much easier to instead use a »vanilla« TeX Live installation, see for example How to install “vanilla” TeXLive on Debian or Ubuntu?

Does anyone know the meaning of line 4878 on siunitx.sty ?

Code: [Select all] [Expand/Collapse] [Download] (untitled.tex)

\bool_if:nF
   {
    \sys_if_engine_luatex_p: ||
    \sys_if_engine_xetex_p:
   }

This peace of code inserts whatever is following in the next pair of braces if both LuaLaTeX and XeLaTeX are not used.
