you need a kernel with a 3G/1G split, you most likely have one with a 2G/2G split This pending patch would have printed out a more informal message: https://source.winehq.org/patches/data/109278
Indeed, thanks: pi@raspberrypi ~/wine-git $ ./wine notepad Warning: memory above 0x80000000 doesn't seem to be accessible. Wine requires a 3G/1G user/kernel memory split to work properly. wine: failed to map the shared user data: c0000018
Not sure about the raspberry pi 2, but i guess the easiest way to get a 3G kernel is to compile it yourself setting CONFIG_VMSPLIT_3G=y
Okay, thanks.
