[GRASS-user] running cygwin/grass 6.1, 6.2 and native 6.3 on the same xp machine

GRASS GRASS user

Dear list,

I am currently still with the 6.1cvs cygwin/grass binaries but would like to run the cygwin 6.2.1 and the native 6.3 versions of grass for testing purposes on the same windows xp machine.

To my knowledge, different cygwin/grass versions use different cygwin packages, and the native wingrass requires setting environmental variables that may interfere with the cygwin version.

Is there any precautionary measures I should take in order to avoid interference between the different versions and to be able to test newer versions without losing the ability of working with the old one?

Thanks and regards,

Luigi

There shouldn't be any problem with having multiple Cygwin builds of
GRASS. If there is, I'd suggest moving to 6.2.1. The 6.1 branch ended
with the release of 6.1.0; there won't be any updates.

As for conflicting environment variables: I suggest editing MSys'
/etc/profile (or ~/.profile etc) to explicitly clear any
Cygwin-related settings. Specifically, unset the CYGWIN variable;
there shouldn't be any other applicable variables.

Thanks Glynn:
Really an authoritative reply – I couldn’t ask for anything more.
