Problem cross-compiling Qt5 from Ubuntu to Raspbian(Raspberry pi3)

SGaist · wrote on 21 Apr 2017, 20:37

Usually looking at the compiler package provided by the distribution provides that info.

The script itself is pretty fast.

Which version of the script did you use exactly ?

BadBlood · wrote on 22 Apr 2017, 06:42

I don' t know. The script is called fixQualifiedLibraryPaths and I have only the code, no infos about the version:

#!/bin/bash
#This script is ugly, feel free to fix it

if [ "$#" -ne 1 ]; then
    echo "usage ./cmd target-rootfs"
    exit -1
fi

#passed args
ROOTFS=$1
TOOLCHAIN=arm-linux-gnueabihf

INITIAL_DIR=$PWD

function adjustSymLinks
{
    echo "Adjusting the symlinks in $1 to be relative"
    cd $1
    find . -maxdepth 1 -type l | while read i;
    do qualifies=$(file $i | sed -e "s/.*\`\(.*\)'/\1/g" | grep ^/lib)
    if [ -n "$qualifies" ]; then
    newPath=$(file $i | sed -e "s/.*\`\(.*\)'/\1/g" | sed -e "s,\`,,g" | sed -e "s,',,g" | sed -e "s,^/lib,$2/lib,g");
    echo $i
    echo $newPath;
    sudo rm $i;
    sudo ln -s $newPath $i;
    fi
    done
    cd $INITIAL_DIR
}

adjustSymLinks $ROOTFS/usr/lib "../.."

echo "Testing for existence of potential debian multi-arch dir: $DEB_MULTI_ARCH_MADNESS"

if [ -n "$DEB_MULTI_ARCH_MADNESS" -a -e "$DEB_MULTI_ARCH_MADNESS" ]; then
    echo "Debian multiarch dir exists, adjusting"
    adjustSymLinks $DEB_MULTI_ARCH_MADNESS "../../.."
fi

Have you a script you are sure that it will work well? I am trying to cross-compile Qt5

You should have some feedback. One thing I'd do use the full path rather than ~.

BadBlood · wrote on 27 Apr 2017, 05:46

Hi SGaist,

yes I tried to use the full path by command:

./fixQualifiedLibraryPaths /mnt/rasp-pi-rootfs /home/michele/opt/tools/arm-bcm2708/arm-rpi-4.9.3-linux-gnueabihf/bin/arm-linux-gnueabihf-gcc

and what I receiced was this error:

usage ./cmd target-rootfs

Well at that poiint I tried to run this command without the cross compiler path:

./fixQualifiedLibraryPaths /mnt/rasp-pi-rootfs

And I received this:

Adjusting the symlinks in /mnt/rasp-pi-rootfs/usr/lib to be relative
Testing for existence of potential debian multi-arch dir:

But I don' t think it is right as I didn' t use any cross compiler in the command, infact when I after run the command to cross compile, it happened:

Qt is now configured for building. Just run 'make'.
Once everything is built, you must run 'make install'.
Qt will be installed into '/mnt/rasp-pi-rootfs/usr/local/qt5pi'.

Prior to reconfiguration, make sure you remove any leftovers from
the previous build.

Then i run make -j4 and I receveid this error:

Your log is not complete, please restart without the -j parameter so you can have the exact point of failure.

jm1776 · wrote on 1 May 2017, 02:33

@BadBlood The sample commands are wrong. Either you need to && between the individual commands, or run then individually. For example:

./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/rasp-pi-rootfs -opensource -confirm-license -optimized-qmake -reduce-exports -release -make libs -prefix /usr/local/qt5pi -hostprefix /usr/local/qt5pi && make -j 4 && sudo make install

OR

> ./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/rasp-pi-rootfs -opensource -confirm-license -optimized-qmake -reduce-exports -release -make libs -prefix /usr/local/qt5pi -hostprefix /usr/local/qt5pi
> make -j 4
> sudo make install

Also, maybe try to git from github:

> git clone https://github.com/qt/qtbase.git -b 5.8

Change 2) Compiling qt base:

> cd ~/opt/cross-compile-tools
> sudo ./fixQualifiedLibraryPaths /mnt/rasp-pi-rootfs/ ~/opt/gcc-4.7-linaro-rpi-gnueabihf/bin/arm-linux-gnueabihf-gcc

Also, take a look at this bug if you're using raspberrypi/tools:
Update toolchain to support gcc 4.9 raspi3/jessie #73

Thank you very much guys,

I had some problems with cross-compiling and I couldn' t to reply to SGaist. Thank you for && advice, i didn' t know that, and thank you for the link.

I couldn' t reply to SGaist beacuse I wanted to repeat all passages: I had problems with the cross compiling configuration command. In particular when I run the command:

./configure -opengl es2 -device linux-rasp-pi-g++ -device-option CROSS_COMPILE=/home/michele/opt/tools/arm-bcm2708/arm-rpi-4.9.3-linux-gnueabihf/bin/arm-linux-gnueabihf- -sysroot /mnt/rasp-pi-rootfs -opensource -confirm-license -optimized-qmake -reduce-exports -release -make libs -prefix /usr/local/qt5pi -hostprefix /usr/local/qt5pi

ERROR: Cannot compile a minimal program. The toolchain or QMakeSpec is broken.

Check config.log for details.

So I check the config.log and his content is this:

@SGaist said in Problem cross-compiling Qt5 from Ubuntu to Raspbian(Raspberry pi3):

Your log is not complete, please restart without the -j parameter so you can have the exact point of failure.

Hi SGaist, sorry for delay

The problem was the cross compiler, if I made the configuration with 4.9.3 v. It returned me the error I attached, but if I use the other one(4.7) cross compiling configuration works fine.

However when i run "make" I had the error. As the log is too big to attach here, i will send you the one drive link to the log file containng the error I received.

I can't see any error in the file you shared.

Sorry but the files was cutted. Now i have the correct one:

You can try the workaround described here.

Hi SGaist,

I had another error but the last disappered, i will link the log file.

First lines were cutted, but there are the most important about the error.

I'd still opt for changing to a more recent version of gcc like 4.9

BadBlood · wrote on 29 May 2017, 05:45

I tried to use gcc 4.9, but it returns the error during cross compiling configuration, I linked few weeks ago. The cross compiler I chose is in the directory:

/home/michele/opt/tools/arm-bcm2708/arm-rpi-4.9.3-linux-gnueabihf/bin

I was able to create a raspbian with Qt5 following the guide at this link:

https://medium.com/@amirmann/how-to-cross-compile-qt-for-raspberry-pi-3-on-linux-ubuntu-for-beginners-75acf2a078c

Next I put the image onto SD card, and there was all files.
But i had problems to find raspberry with the laptop through QT5 running on that, I' m going to open an other topic for that. Thank you.

If it hasn't already been noticed the path setting script checks the number of parameters passed and is expecting 1 but 2 are being passed. I changed "$#" -ne 1 to "$#" -ne 2 and it ran without the error message.

The second parameter is used in the script so it is needed.

However I now get an error 'Cannot run compiler '/home/sam/opt/gcc-4.7-linaro-rpi-gnueabihf/bin/arm-linux-gnueabihf-g++'

(It does exist there)

can you run it manually from a terminal?
