[Qgis-user] 3GB limit in osgeo4w's Qgis Master

[Gerardo Jimenez]

Hi
according to this
http://gis.stackexchange.com/questions/31891/does-osgeo4w-install-a-32-bit-or-64-bit-version-of-qgis
even if you installed master is istalled as a 32 bits aplication, therefore you can not use all your RAM. Try it in a linux or Mac environment.

Subject: [Qgis-user] 3GB limit in osgeo4w's Qgis Master

Hello all,

I'm using qgis-dev (Master) from osgeo4w to obtain some landscape metrics (LeCos plugin). I'm under Windows 7 Home Premium 64-bit, with 12 GB RAM, but when running LeCos or any sextante algorithm windows gets stucked at 3 GB limit (sometimes 3.x GB), and I have plenty of RAM (nearly 8 GB) wasted.



Is this a limitation coming from osgeo4w's 32-bit libraries?
Is it possible to use my whole RAM under Windows 7 64-bit or should I go to GNU/Linux?

Thank you very much in advance for your insight.

Yasser
