please install the mediawiki-math package

Hi,

please install the mediawiki-math package, it allows us to use TeX markup for formulae.

​http://meta.wikimedia.org/wiki/Help:Formula

ISTR that this worked some months ago (Apr 2009?), but now it does not.

​http://grass.osgeo.org/wiki/Atmospheric_correction#Calculating_radiance_values

(<!-- new TeX version commented out there -->)

Something to keep an eye on: on Debian/lenny it sucks in a lot of TeX foreign language support packages which togethwe weigh in at ~500mb installed! (in addition to the standard TeX packages which were already present)

thanks, Hamish

now when I try <math> I get this error:

Failed to parse (Missing texvc executable; please see math/README to configure.)

On Aug 2, 2009 I have compiled texvc and put it into /usr/local/bin/. Perhaps a link into /usr/bin/ is sufficient to make it visible to Mediawiki?

[neteler]

The executable is in /osgeo/grass/grass-wiki/math/texvc

but still no go. Looking at ​http://www.mediawiki.org/wiki/Manual:Enable_TeX/problems#Error_:_Failed_to_parse_.28Missing_texvc_executable.29

doesn't give me any idea.

done.

For the record, after Debian upgrade, to fix the math captcha:

# projectsVM:
cd /osgeo/grass/grass-wiki/extensions/Math/math/
make clean
make
cp texvc_tex texvc_test texvc /usr/local/bin/

[neteler]

After move to new hardware (osgeo6) and fresh Debian installation there, the page

https://grass.osgeo.org/wiki/Atmospheric_correction#Calculating_radiance_values

is not rendered properly.

I have tried to install the math extention:

  cd /var/www/grass/grass-wiki/w/extensions/Math/math/
  aptitude install texlive-base texlive-latex-base aptitude install ocaml
  make clean &&  make
  cp texvc_tex texvc_test texvc /usr/local/bin/

  cd /var/www/grass/grass-wiki/w/extensions/Math/texvccheck
  make clean &&  make
  cp texvccheck /usr/local/bin/

but something else must be missing (again, complete new installation).

Reopening. Ideas?

Replying to neteler:

After move to new hardware (osgeo6) and fresh Debian installation there, the page

is not rendered properly.

should be fixed by upgrading to Mediawiki 1.25. Martin

Thanks!
