Hi all, Is there any option to overcome the 2GB memory limitation on a windows 32 bit. with mingw64. Earlier I was using mingw32 from mingw.org and there seems to problem on 32bit windows. Especially when I want to allocate a RAM of more than 3 GB.
I moved to mingww64 toolchain and the problem still persist. with mingw64 x86_64 is working just fine with > 2GB. For mingw32 @ mingw.org I couldn't find any related issues. So maybe there isn't any problem(which is wrong) or none is using mingw32. For mingw64 project I can find a feature request at least that make me drop mingw32. Anyway... On a 64bit system with 3GB ram it is working but on a 32bit system with 4GB ram the same code is not working. To reproduce try to allocate a larger memory on 32bit windows. snippet of code using calloc. This code fails on 32bit and works on 64bit w = 14029 h = 14012 band = 3; imagebuffer = (uint32_t*) calloc(w*h*band, sizeof(uint32_t)); -- Regards, Rashad
