Re: [GRASS-user] Database driver problem
I installed a previous version R38537-1 and attempted the exact same connection as before under the exact same conditions. The connection was successful and returned the correct values with the previous install where as it returns errors under the current install. Something has changed between 38537-1 and 39271-1 in a manner that breaks the ability of the software to connect to dbfs. -Erik -- View this message in context: http://n2.nabble.com/Database-driver-problem-tp3720138p3767711.html Sent from the Grass - Users mailing list archive at Nabble.com. ___ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user

Submitting it would get it at least into the next test compilation. I suggest committing it. As it stands, dirpath will contain a mix of forward slashes and backslashes, which is the worst possible case (there are two ways that it could break). In the longer term, we should really try to get rid of forward slashes on Windows altogether, rather than fixing the individual cases where they don't work. -- Glynn Clements gl...@gclements.plus.com ___ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user

G_spawn_ex() supports background processes, but it doesn't support redirecting descriptors on Windows. The only way to fix that is to re-write it to use CreateProcess() rather than spawnvpe(); Python's subprocess module would probably be a useful source of clues. -- Glynn Clements gl...@gclements.plus.com ___ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user

Unfortunatly GRASS has no Windows developers. Developers use Linux or Mac and not windows and thus fixing Windows specific bugs is hard.

Thanks for the tip but I've no idea of how to re-compile . Can this be done from within the software or do I need to use something like Dev C++?

Re: [GRASS-user] Database driver problem
Also previous patch should not be commited to anywhere. I just want to know (get info) what's going on when db spawn call fails. If somebody can recompile with that tickets patch and then post results to trac, we may get an idea what's failing. I suspect forward vs backward slashes issue. Still without exact info it's hard to tell. Also unless somebody is going to test various patches/ticket fixes on windows, windows version will suck hard (die, die!).
