I downloaded both (i386 and amd64) versions, and the only difference is that libinkview.so has been moved from /usr/lib/ to /lib32/ in the amd64 version. Everything else is the same. I was previously running sergeyvl12's older SDK under a 32-bit system inside VirtualBox. I don't mind using the VirtualBox emulator for the BUILD=emu stuff, since I don't do it that often. But I was hoping to be able to build the BUILD=arm and BUILD=arm_gnueabi targets natively on my 64-bit system. Oh well.
If you can cross-compile to the ARM targets now, then you already have the 32-bit compatibility libraries installed on your system. The /usr/bin/arm-* programs would not run without them on a 64-bit system.
If you are installing using a package manager, then 'ldconfig' is probably already being executed on your system. Running
/sbin/ldconfig -p | grep inkview will show you if libinkview.so is already cached and can be used for building. If it isn't, then just run 'ldconfig' as root, and it will be.
I don't know how to set up QtCreator or any other IDE. I'm a command-line kind of guy
