[Qgis-user] Re: QGIS intallation, Windows XP, TIFFUnsetField, libtiff.dll

[Patrick Giraudoux]

Dear all,

To trigger a hoax about Windows/Linux comparison and QGIS vertues/misery 
was far from my mind when I send this (I was believing naively) simple 
and technical question to the list: how to get out of this and make 
things work (see below) ?

I am a faithfull user of GRASS and QGIS in both environments (Windows 
and Linux Ubuntu).  I can hardly understand the chain of reactions and 
my only response was to send offlist to Mats: " Do not understand the 
reason for your "rant". The trouble I meet does not come from Windows XP 
but likely from the QGIS installer". By this, I do no mean any reproach 
to developpers kind enough to work on tools which are useful to the user 
community (and the students) and would hate to give them a bad feeling. 
I just try to behave as a member of a user community, e.g. to signal 
possible troubles and be ready to put ashes on my head if some of my 
questions are idiotic or coming from an inadequate analysis of the 
situation.

However this discussion about Windows and QGIS amplifying, it does not 
provide an answer to the initial two simple, sincere, and technical 
questions of a simple user, reminded below (lost for ever ?)...

Any hint ?

Cheers,

Patrick
