Qt5.7 on Pi Basics

Qt5.7 on Pi

On PC

Create a directory where you will be working from
mkdir ~/raspberry cd ~/raspberry
Save env variables to the setdevenv.sh file
#!/bin/sh WORKINGDIRECTORY=$HOME/raspberry TOOLCHAIN=gcc-4.7-linaro-rpi-gnueabihf MOUNTPOINT=/mnt/raspberry-rootfs export PATH=$PATH:$WORKINGDIRECTORY/$TOOLCHAIN/bin
Download and unzip gcc for raspberry pi
wget http://www.tequnique.com/dl/raspberry/gcc-4.7-linaro-rpi-gnueabihf.tbz tar xfj gcc-4.7-linaro-rpi-gnueabihf.tbz
Install libraries so we could compile for 32bit arch.
sudo apt-get install ia32-libs

On Pi

Update and Upgrade Pi ssh pi@"raspberry ip address" sudo apt-get update sudo apt-get upgrade
Enable some stuff for QT sudo apt-get install libfontconfig1-dev libsqlite3-dev libxslt1-dev libssl-dev libasound2-dev libavcodec-dev libavformat-dev libswscale-dev libgstreamer0.10-dev libgstreamer-plugins-base0.10-dev gstreamer-tools gstreamer0.10-plugins-good gstreamer0.10-plugins-bad
sudo shutdown -h now

Back to PC

Make an image of your Pi Image cd ~/raspberry sudo dd if=/dev/sdb of=raspberry-working-image.img
Mounting get sometimes tricky... sudo /sbin/losetup /dev/loop0 raspberry-working-image.img

$ sudo /sbin/fdisk -l /dev/loop0
Disk /dev/loop0: 29.7 GiB, 31914983424 bytes, 62333952 sectors

Sector size (logical/physical): 512 bytes / 512 bytes

sudo mount -o loop,offset=$((137216*512)) raspberry-working-image.img /mnt/raspberry-rootfs
Run the script to set new env variables source setdevenv.sh
Download cross compile toolchain git clone https://gitorious.org/cross-compile-tools/cross-compile-tools.git cd cross-compile-tools
sudo ./fixQualifiedLibraryPaths $MOUNTPOINT ~/raspberry/gcc-4.7-linaro-rpi-gnueabihf/bin/arm-linux-gnueabihf-gcc
