[Qgis-developer] Re: qgssvnversion.h and compile problem

[Gavin Macaulay]

Hi,

I don't think that Tim's suggestion for replacing qgssvnversion.h would
work. Having some special text in a file that svn automatically replaces
with the version number (aka $Id:$ with cvs) will result in something that
only gets updated when that file is changed. For example, if a commit is
made to a separate file, svn won't update the file that contains the
special text.

As far as I can see, running the svnversion command and placing that
output somewhere where qgis can see it (at compile time or run time) is
the only way to get an up-to-date version number.
