[QtonPi] Fwd: Beginner's problem compiling Qt5

Sat Aug 25 09:45:32 CEST 2012

Hi,

Have you tried mounting the Pi's filesystem through sshfs and then
re-run the make install steps of each Qt module. Ought to work if the
libs on the image you used when cross compiling and those of your
system are ABI compatible.

Best regards,

Johan Thelin
