Thanks for the advice. I read in this group about previous attempts (including yours) building on ARM Android devices, which encouraged me to try it on Sailfish. At the moment my build is still chugging away, although it got killed earlier and I had to set it off again (but it seems to be making progress again now).
If it fails again I'll look into the possibility of emulation, but then I'll probably have to build my own Mer images, which I'd rather avoid! Too bad about the cross-compiling, but I'm sure making the build changes falls well outside my capability. So, I'll stick with attempting to build on the device until either it or I get stuck. Thanks again for the very useful advice. On Wednesday, 17 February 2016 12:40:08 UTC, mmarco wrote: > > Long ago i succeded at compiling sage in an arm tablet.
