Thank you! Not finding the loader was the problem. I think this makes sense since classic confinement only mounts the bin directories from the snap packages, other directories, e.g. /lib, use the host directory. Just for the record, the following works for me: $ export HOSTFS=$SNAP $ export LD_LIBRARY_PATH="$HOSTFS/usr/lib/i386-linux-gnu/libfakeroot:$HOSTFS/usr/local/lib:$HOSTFS/lib/i386-linux-gnu:$HOSTFS/usr/lib/i386-linux-gnu:$HOSTFS/usr/lib/i386-linux-gnu/mesa-egl:$HOSTFS/usr/lib/i386-linux-gnu/mesa:$HOSTFS/lib32:$HOSTFS/usr/lib32:$LD_LIBRARY_PATH" $ export PATH="$HOSTFS/usr/local/sbin:$HOSTFS/usr/local/bin:$HOSTFS/usr/sbin:$HOSTFS/usr/bin:$HOSTFS/sbin:$HOSTFS/bin:$HOSTFS/usr/games:$HOSTFS/usr/local/games:$PATH" $ $SNAP/lib/ld-linux.so.2 $SNAP/usr/bin/pharo-vm/pharo --version On Tue, Apr 04, 2017 at 03:17:05PM +0000, Sergio Schvezov wrote: > I am not sure how the low levels work here wrt to program loaders and > 32bit versus 64bit support, if they are different, there is currently > no support in snapcraft for this, which for classic confined snaps > sets the program loader to a specific binary, you can of course > override this with a combination of LDFLAGS to set the loader to > something more appropriate (just make sure the loader comes from the > core snap or you won't be cross distro or even cross series on > Ubuntu). This is what I'll try next. pharo isn't working properly at the moment because it looks for files relative to the executable, and manually loading pharo using ld-linux.so.2 is confusing that code. But this needs further investigation on my part (just setting the dynamic-linker in LDFLAGS isn't working). > > The project is at: https://github.com/akgrant43/pharo-snap > > I'm just changing the confinement to classic to reproduce the problems. > > You can't just switch the confinement value, you will need to rebuild. Yep, I'm doing this. Thanks again, Alistair -- Snapcraft mailing list Snapcraft@lists.snapcraft.io Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/snapcraft
