Setup environment to compile for Raspberry

  • Hi,
    I try to setup environment to be able to compile application Qt for Raspberry.
    I follow the this tutorial but I have an error when I try to configure :

    $./configure -opengl es2 -device linux-rasp-pi-g++ -device-option CROSS_COMPILE=~/opt/gcc-4.7-linaro-rpi-gnueabihf/bin/arm-linux-gnueabihf- -sysroot /mnt/raspberry-rootfs -opensource -confirm-license -optimized-qmake -reduce-exports -release -make libs -prefix /usr/local/qt5pi -hostprefix /usr/local/qt5pi -v

    I have tried several times the procedure and I always have the error.

    You should run fcheck fsck on your RPi sdcard. An In/Out error usually means that some data got corrupted or more likely the data storage.

  • Does that mean that .img are a problem ? If I test with Raspbian image, it should work ?
    What is fcheck ? A command line ?

    Sorry, I meant fsck.

    You got an IO error on a mounted disk image ?

  • When I insert my SD Card, I have on dmesg :

    [ 1597.464008] sd 3:0:0:0: [sdb] 15482880 512-byte logical blocks: (7.92 GB/7.38 GiB)
    [ 1597.470203]  sdb: sdb1 sdb2
    [ 1597.886246] EXT4-fs (sdb2): recovery complete
    [ 1597.886254] EXT4-fs (sdb2): mounted filesystem with ordered data mode. Opts: (null)
    [ 1597.909332] FAT-fs (sdb1): Volume was not properly unmounted. Some data may be corrupt. Please run fsck.

    When I run fsck, I have :

    $sudo fsck /dev/sdb1
    fsck de util-linux 2.20.1
    fsck.fat 3.0.26 (2014-03-07)
    0x25: Dirty bit is set. Fs was not properly unmounted and some data may be corrupt.
    1) Remove dirty bit
    2) No action

    After correction, if I insert the card, I have :

    [ 2116.065860] sd 3:0:0:0: [sdb] 15482880 512-byte logical blocks: (7.92 GB/7.38 GiB)
    [ 2116.071942]  sdb: sdb1 sdb2
    [ 2116.461258] EXT4-fs (sdb2): mounted filesystem with ordered data mode. Opts: (null)

    I will try again the procedure.

    Thank for your help

  • The problem of seems solved but I have an other error :

    Running configuration tests...
    Failed to process makespec for platform 'devices/linux-rasp-pi-g++'
    Project ERROR: Compiler /home/helene/raspberry/gcc-4.7-linaro­-rpi-gnueabihf/bin/arm-linux-gnueabihf-g++ not found. Check the value of CROSS_COMPILE -device-option

    Are you shutting down the RPi properly ?

    Does /home/helene/raspberry/gcc-4.7-linaro­-rpi-gnueabihf/bin/arm-linux-gnueabihf-g++exists ?

  • I succeed to setup environment but I can't succeed to run a simple project.
    I had

    • debugger (Path : /home/helene/opt/gcc-4.7-linaro-rpi-gnueabihf/bin/arm-linux-gnueabihf-gdb)
    • compiler (Path: /home/helene/opt/gcc-4.7-linaro-rpi-gnueabihf/bin/arm-linux-gnueabihf-g++)
    • Qt version (qmake path : /usr/local/qt5pi/bin/qmake)
    • Kit

    But I don't know why, version is to Qt 5.6.1 ans when I run my application, I have the error :

    avertissement : You are using deprecated mkspecs. Please use qnx-armle-v7-qcc instead.
    erreur : qcc: Command not found

  • Lifetime Qt Champion

    QNX ? Did you change anything in the mkspec ?

  • No, I don't think so.
    Is this normal, I have Qt 5.6.1 (not 5.4.1 ?)

  • Lifetime Qt Champion

    Did you clone directly from ?

  • Yes.
    I have tried again with qt-everywhere-opensource-src-5.4.1 and it works.

  • Lifetime Qt Champion

    What about 5.5.1 ?

  • I didn't try. 5.4.1 is enough for me
