I'm assuming from what I've read in the forums that Wine reserves 1GB for Linux and can't allocate more than 3GB for Windows programs without a patch. I replaced "dlls/ntdll/virtual.c" # define ADDRESS_SPACE_LIMIT ((void *)0xc0000000) /* top of the total available address space */ # define USER_SPACE_LIMIT ((void *)0x7fff0000) /* top of the user address space */ with # define ADDRESS_SPACE_LIMIT 0 /* no limit needed on other platforms */ # define USER_SPACE_LIMIT 0 /* no limit needed on other platforms */ When I compile something without this patch, Wine seems to use the Linux swapfile before it uses the 1GB Wine reserves for Linux. But, when I use this patch, Wine seems to go into the 1GB reserved for Linux and corrupts what I'm trying to compile. With this patch, is there a way to keep Windows programs from using the 1GB reserved for Linux, and using the swapfile instead?
