NAV 4.2 does not work with SASS 3.4 or newer, but the install docs do not specify this

[Ingeborg Hellemo]

OS FreeBSD 10.1

NAV installed from src distribution, both 4.1 and 4.2

The nav.css file in the src distribution is flawed and the resulting web page looks like a plane crash site.

We have solved this by copying nav.css from "verktøykassen".

[John-Magne Bredal (john-m-bredal)]

The css is created by compiling .sass files with sass.

Running this manually will give some error that we would be interested in. My guess is that your sass version is out of date or incompatible with the latest sass format.

Go to htdocs and run make clean; make, and take a look in the generated css/nav.css file.

Or perhaps to new? rubygem-sass-3.4.5

No errors during compiling

Thanks for the detailed log.

You are totally correct in that the version you are using is too new and has backwards incompatible changes. Luckily an update of the sass-files was scheduled for 4.3, so this is already solved for that version of NAV. Until that is released you have to use sass 3.3 to compile the sass-files.

Howto install sass version:

gem install sass -v 3.3.9
gem uninstall sass
(you will be able to choose version)

remove all css files in htdocs/static/css
run make

[John-Magne Bredal (john-m-bredal)]

It is of course better to do
make clean; make

In case there are more 4.2.X-releases it is wise to update
doc/intro/install.rst with a "< 3.4"

John-Magne, I see you tried to fix the documentation in https://nav.uninett.no/hg/stable/rev/0e732300b628, but there is a typo. Making a follow-up fix in https://nav.uninett.no/hg/stable/rev/76ab0875b2d8.
