Hi Allen I think this is an issue with the cygwin memory mapping/allocation. I have large memory rquiirement perl scripts that run fine as a native compile but fail under cygwin with out of memory. I have never got Cygwinto use all the available memory, independent of the application. I just added DX to my list!
I would follow the advice of many (most) windows users here and spend the few dollars on the Vis Solutions windows version. These work really well and utilise the entire memory you allocate. This is the most sensible solution when comparing it to the long hours it will take you to, perhaps, get the cygwin version doing what you want. Hope that helps Peter -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Allen H. Nugent Sent: 08 February 2004 00:00 To: [email protected] Subject: [opendx-users] memory problems with cygwin openDX on Windows 98 Dear DXplorers, I posed this question before Christmas, but I didn't get any advice that was pertinent to the Windows 98 platform, and I thought it might have been largely subordinated by holiday preparations. I can't get DX to use more than 24 MB, although I have 512 MB installed. This means it crashes with big data sets, medium-sized "Save Image" requests, or mouse-driven Rotate operations of medium-sized data sets in the Image control. The command $ DX -memory 256 has no effect. Is there a configuration tweak I can make, or is this an absolute limitation of cygwin openDX on Win98? Allen H.
