Cross-compile Qt 5.7.1 error on make and partial rsync permission issues.

ShengS

Following the up-to-date (modified on on 23rd of November 2016) qt wiki article -> https://wiki.qt.io/RaspberryPi2EGLFS and with respective changes to downloading Qt opensource everywhere instead of Qt base, and it is targeting raspberry pi3 b, and with respect to that, the x64 was added also to the -device-option CROSS_COMPILE...; the following errors occured:

and while syncing the pi, another issue was presented also.

as ambershark has recommneded, here's the new topic for everyone who is having similar trouble and let's work this out and onwards to the exciting embedded device creation.

Cheers!

@ShengS "/root/raspi/sysroot" - are you working as root?! You should never do that!
Does your sysroot/toolchain contain stdio.h?

ShengS

@jsulm yeah, I am XD, thanks for the heads up, was having problem with my connections recently, and having very little sleep, since that was my third attempt to get this to work, I completely forgot to cd back to the usr account, okay, start from scratch from normal usr account, thanks for the heads up.

rsync: send_files failed to open "/usr/lib/cups/backend/vnc": Permission denied

I also have this same problem, I presume it is not a problem since I'm unlikely to need those. But I wonder if we should use some other command to rsync.
