[osgeo4w-dev] osgeo4w portability

[Matt Wilkie]

Hi Folks,

A discussion started off-list about a portable Osgeo4W (here
<https://github.com/maphew/apt/issues/10#issuecomment-73048724>).

Jurgen observed that *"most of the batch files are "portable", but we also
have configuration file templates* that are modified in postinstall using
textreplace. That's essentially why it exists. *

*BTW another problem with portability are the msvcrt packages - that need
to be installed." *[ *c.f. the batch shell template
<http://trac.osgeo.org/osgeo4w/wiki/PackagingInstructions#Applicationbatchfiletemplate>
]
I've used o4w portably for a long time by simply copying C:\Osgeo4W tree to
a usb stick and I've not run into problems, but I mostly use just the gdal
command line utils. I thought it would be good to collect and/or itemize
the particular packages or configurations that break portability. We could
then look and see if it's unavoidable or there might be some reasonably
inexpensive way of changing that.

This this thread; what doesn't work portably right now?

Matt
