Anyone had any success at all?
This is what I did:
1) Edit bottlecaps-qt.pro and remove the "msse2" flags
2) Edit bottlecaps-qt.pro and add "src/scrypt-arm.S \" right after "src/scrypt-x86_64.S \"
3) Add the scrypt-arm.S file to the \src folder
You can get this file from a number of other wallets. I used the one optimized for the ARMv7 and modificed for the Pi 2 DMD wallet. Get it here: https://github.com/feldenthorne/Diamond
4) Edit scrypt_mine.cpp and remove "#include
5) qmake "USE_UPNP=1"
6) make
Voilà! A fully functional qt-wallet for the Rasberry Pi 2
Good luck! :-)
