weft qda users - Feb 2006 - [Weft QDA users] Problems installing and with character coding

Hi!

I have two different problems with weft:

On one machine, running unbunt linux (breezy badger), i have weft up and 
running. But when trying to create a new project I run into problems. I 
import text files into the project, and that''s fine. But when viewing 
the files, problems occur. Either there is not text displayed at all - a 
frame appears but it is empty. This seems to be the case when the file 
is stored with character coding iso-8859-1.

Or, when the file is stored as utf8, it shows, but the swedish 
characters are displayed incorrectly, as strange characters.

My system locale is utf8.


My second problem is installation of weft on a debian unstable machine. 
I have downloaded the weft-qda-1.0.0 source, but when trying to install 
sqlite-ruby-2.2.3, i get the following:

vista4:/home/magnus/weft/sqlite-ruby-2.2.3# ruby install.rb
cp ext/extconf.rb ext/sqlite-api.c build
cp -r lib build
cd build
extconf.rb:1:in `require'': no such file to load -- mkmf (LoadError)
        from extconf.rb:1
could not configure sqlite module


I have the following installed:

vista4:~# dpkg -l | grep sqlite
ii  libdbd-sqlite-ruby              0.0.23-3                    Ruby/DBI driver

ii  sqlite                          2.8.16-1                    command line

Any ideas on what to check or do?

Hi Magnus

Thanks for the info on Linux. Your second problem is more 
straightforward...

mkmf is part of Ruby''s standard library, used to help build c-extension
modules. Though it would come with any source build of Ruby, it looks 
like Debian splits it into a separate package, called ruby1.8-dev . if 
you install this package using apt, sqlite install should be fine. A bit 
more info in the URL  below:

I tested some French text today on Ubuntu warty (an older version), and 
all worked fine - accented characters are acceptable in document text, 
category names, memos etc. but -- my system locale is en_GB.iso88591

Ubuntu, it seems, with the breezy release, was the first major linux 
distro to move to UTF-8 as the system locale. In the big picture 
(standards compliance, multilingual support) this is a good thing, but 
it''s a pain for Weft. Weft uses wxruby-0.6.0, which doesn''t
support
UTF-8. Accented characters in documents only work where the system 
locale matches the document file encoding, and isn''t UTF.

It might be possible to run Weft on breezy by creating an environment 
where the locale is set to something more congenial. You could change 
your system''s default locale - a quick google suggests something like 
''dpkg-reconfigure locales'' - but you might not want to do
this.

You could also try adjusting just the environment that Weft is running 
in. I can''t really test this without breezy installed, but as a first 
step, you might try altering environment variables in your shell before 
running Weft, eg:

export LC_CTYPE=en_GB.iso88591
(and possibly other variables - you will want a swedish language flag, 
not en_GB)

Also some documents seem to suggest you can choose a session locale when 
logging into Ubuntu. Try an iso-latin one instead of UTF-8 and see if 
this helps.

In the longer run this will be solved in Weft version 2.0, which will 
use wxruby2, which supports UTF-8 - so all projects will be 
multilingual-enabled. But wxruby2 is some time away from being ready, 
and Weft 2.0 is really just an apple in my eye at the moment ...

Hope some of this is helpful, do let us know how you get on.
