[gdal-dev] Re: Swig-problem, possibly

[Tomas R]

  It seem like, after a friend checked the wrap-files with Dependency 
Walker, that there are references to msvcr100.dll and msvp100.dll which, 
as far as I know, are runtime files from Visual Studio 2010.
is that really as it should be? Should really the result depend on files 
from the environment it was compiled in? Must I go back to VSE2008 and 
recompile Gdal to make it work on all machines or is there a setting 
somewhere...


Yours
Tomas
