[Qgis-user] recompiling gdal: problems with QGIS?

[Agustin Lobo]

Thanks,

Therefore, I understand I should not try to make the current QGIS I have
work with a new compiled gdal.
BUt could I have a second version of gdal
which I would use for converting ECW and MrSid files to formats that
QGIS can accept?
