Cross - compilation error Qt5 for Raspberry Pi 2 [SOLVED]
MarKS last edited by MarKS
I was following this link
http://exploreembedded.tumblr.com/post/115333857238/guide-to-cross-compile-qt-54-for-the-raspberry-pi to setup my cross tool chain for Raspberry pi 2.
I ran into error when i tried to execute
./configure -opengl es2 -device linux-rasp-pi-g++ -device-option CROSS_COMPILE=$RPI_TOOLCHAIN -sysroot $RPI_SYSROOT -opensource -confirm-license -optimized-qmake -reduce-exports -release -make libs -prefix /usr/local/qt5pi -skip qtwebkit

Running configuration tests...
Warning: Disabling pkg-config since PKG_CONFIG_LIBDIR is not set.
Note: PKG_CONFIG_SYSROOT_DIR automatically set to /mnt/rasp-pi-rootfs
Could not determine the target architecture!
Turn on verbose messaging (-v) to see the final report.
The OpenGL ES 2.0 functionality test failed!
Use of pkg-config is not enabled, maybe you want to pass -force-pkg-config?
You might need to modify the include and library search paths by editing
QMAKE_INCDIR_OPENGL_ES2, QMAKE_LIBDIR_OPENGL_ES2 and QMAKE_LIBS_OPENGL_ES2 in
make: *** No targets specified and no makefile found. Stop.
Tried to find a way around on the internet but couldn't get it working.
Did you mount the Raspberry Pi root file system in

I am getting this :
ya@ya-pc:~$ sudo mount –o loop,offset=62914560 /Downloads/2015-05-05-wheezy-raspbian.img /mnt/rasp-pi-rootfs
Usage: mount -V : print version
mount -h : print this help
mount : list mounted filesystems
mount -l : idem, including volume labels
So far the informational part. Next the mounting.
The command is `mount [-t fstype] something somewhere'.
Details found in /etc/fstab may be omitted.
mount -a [-t|-O] ... : mount all stuff from /etc/fstab
mount device : mount device at the known place
mount directory : mount known device here
mount -t type dev dir : ordinary mount command
Note that one does not really mount a device, one mounts
a filesystem (of the given type) found on the device.
One can also mount an already visible directory tree elsewhere:
mount --bind olddir newdir
or move a subtree:
mount --move olddir newdir
One can change the type of mount containing the directory dir:
mount --make-shared dir
mount --make-slave dir
mount --make-private dir
mount --make-unbindable dir
One can change the type of all the mounts in a mount subtree
containing the directory dir:
mount --make-rshared dir
mount --make-rslave dir
mount --make-rprivate dir
mount --make-runbindable dir
A device can be given by name, say /dev/hda1 or /dev/cdrom,
or by label, using -L label or by uuid, using -U uuid .
Other options: [-nfFrsvw] [-o options] [-p passwdfd].
For many more details, say man 8 mount .
What do you get with:
mount -v -o offset=62914560 -t ext4 /Downloads/2015-05-05-wheezy-raspbian.img /mnt/rasp-pi-rootfs

@SGaist Thank you for the help. I checked that the /mnt/rasp-pi-rootfs was not mounted properly so hence the error. SOLVED.
Since you have it working now, please update the thread title prepending [solved] so other forum users may know a solution has been found :)
Also, while browsing the forum, consider up-voting answer that helped you, that will make them easier to find for everybody :)
